绿色基础设施的未来新格局

The Future Pattern of Green Infrastructure

一次中美规划设计师之间的对话
A Dialogue among Planning Designers from China and America

编者按：深圳市北林苑景观及建筑规划设计院，作为中国绿色基础设施规划研究先行者——广东绿道的全程参与方，在都市群绿色基础设施及绿道的规划设计中发挥了重要力量，并将中国城市水土保持与风景园林的优势进行了开创性的融合；SWA集团，美国著名规划设计机构，致力于通过基础设施与城市设计的路径来发挥景观的最大潜能，在全球多个国家的不同项目中有着成功的实践经验。早在20世纪90年代，北林苑就邀请SWA集团来到中国，在设计理念、项目实践等方面展开广泛交流与合作，为中国本土规划设计企业开拓全球视野、增进国际交流、促进行业健康良性发展树立了典范。在本期绿色基础设施专题的组织策划中，经过几番努力，本刊特别邀请到SWA集团的总裁格杜·阿基诺先生和洛杉矶事务所执行董事、美国南加州大学客座教授洪盈玉女士，以及深圳市北林苑景观及建筑规划设计院总规划师何昉院长和锁秀总监就“绿色基础设施的未来新格局”话题，展开了一次中美规划设计师之间的对话。

《风景园林》：中国总理李克强最近在讲话中提出要“建设一个生态文明的现代化中国”，提出将优化国土空间开发格局，形成合理的生产空间、生活空间、生态空间。在这样一种新的时代背景下，如何理解绿色基础设施在其中的作用和意义？

格杜·阿基诺：一座城市的发展和经济前景与其在广阔地域内收集、交换和调配货物服务、资源、知识和人员的能力成正比。中国政府已经表示，21世纪的发展将以生态可持续性为重点。这意味着绿色基础设施理论将在规划过程中得到重点考虑和讨论。随着城市人口的不断增长，开放空间和自然资源变得更加宝贵。绿色基础设施理论可以指导我们更有效率地使用土地，更可持续地利用资源，并且教育更多的下一代全球公民理解和爱护我们的公共资源。

何昉：应该讲，在国家战略中体现尊重自然的思想，是中国文化传统的继承和发展。生态环境和城市建设之间，或强调保护或强调发展，均有失偏颇。中国城市化进程很快，而城市建设，是一个几乎不可逆的过程，一旦变为建设区，想要恢复成自然地，就要付出很大的代价。绿色基础设施作为都市的“生命支撑系统”，它提供了一种发展方式，影响着城市的空间形态。其“基础”作用应得到足够的重视，其规划实施方案应当要被国家政策所倡导。

《风景园林》：绿色基础设施作为力求让自然与人类发展双赢的积极策略，其推广和发展有着较长的过程。各位可否为我们简要介绍一下国内外在这方面的发展情况？

洪盈玉: 我先来介绍一下在美国的大致发展。皮埃尔·贝兰杰在十多年前首创“景观基础设施”一词，并帮助塑造了这项理论的传播和实践。他倡导的学术课题已经被纳入哈佛大学设计学院、德州大学奥斯汀分校和宾夕法尼亚大学等多所院校的风景园林规划与设计课程。

由于世界范围的城市面临着新建和翻修基础设施系统的急迫需求，设计和规划专业人士有一个重要的机会，可以重新构想能够支持多种用途和功能的系统网络。例如，美国的基础设施正以惊人的速度老化。美国的州际高速公路系统投入使用已经 80 多年，在使用量增长的压力之下不堪重负。作为传统的单一用途系统，高速公路以及高架渠和铁路的承载能力已经逐渐衰退，其结构支持系统亦是如此。正在浮现的一个问题是：景观本身是否能够被视为一种基础设施？它是否能够承担一种运载或分散网络的任务？

格杜·阿基诺：实际上，绿色基础设施这一理论正在被政府机构慢慢接受。他们正在评估基础设施系统的现有能力，以考量其存活能力以及满足未来需要的能力。例如，从 1980 年代中期以来，布法罗河湾的支持者希望看到位于德州休斯顿的这一自然系统走廊的恢复。他们推动了一些新的行动计划，意图先改造走廊的一段，以作为其他区段效仿的榜样。风景园林师和工程师制订了一系列针对现场的特别设计方案，让走廊重归公共领域。

从2007年至2012年，洛杉矶市政府对城市水渠的生态和康乐功能潜力进行了研究，前提是雨洪应该尽快排入大海。在洛杉矶，包括 14.5 km长的巴约纳溪走廊在内的城市河流平均高峰流量为每秒 107m3。2013年3月，洛杉矶市议会投票通过一项试验性提议，将城市水道的一段划为一个为期4个月的康乐活动走廊。这项临时性措施允许民众进入原本的禁区。这是城市将景观基础设施理论纳入公共政策的一项重大尝试。

何昉：在推动中国绿色基础设施的发展方面，我想广东深圳应该算得上是排头兵。20世纪80年代的深圳早期城市规划十分重视城市绿地系统格局，城市呈组团结构分布在陆域平缓区域，城市组团之间预留宽800-1 000m的生态廊道，形成城市被绿地围合的生态格局，城市经过30余年的发展建设，曾经预留的生态廊道现在已经形成城市中的生态公园链。特别是2005年11月，深圳以8处大型区域绿地和18条城市生态廊道组成的生态绿地系统为基础，划定了生态控制线，这是中国第一条划定的城市生态保护控制界线。虽然有其时代的发展局限，但是在城市应对绿地保护和发展矛盾中找到了一种权宜的平衡。

近几年大规模推进的珠三角绿道网规划建设还荣获了全国人居环境建设领域的最高荣誉奖项——“2011年度中国人居环境范例奖”，以及联合国人居署“2012年迪拜国际改善居住环境最佳范例奖”全球百佳范例称号。而广东省绿道网规划、环首都绿道网规划以及包括江苏、安徽、四川、湖南和广西等省区在内的绿道运动在中国方兴未艾。我认为，从生态控制线、城市绿带到绿道，以及珠三角园林城市群和城乡大园林的研究构想，最后到规划实现省城绿色基础设施的全覆盖，广东省都走在发展的前沿，省住建厅正在积极推动这项具有深远意义的工作。

另外，深圳前海规划建设，作为全球首例都市级景观都市主义的实践，我们已经率先进行绿色基础设施全覆盖的规划设计工作，深圳、珠海这样的全国先进城市已率先行动起来，必将带动广东绿色基础设施实现全面完善。

《风景园林》：接着您刚才的话题。您所带领的深圳北林苑不仅全程参与了珠三角绿道网规划建设，并且率先在全国开始探索城市生态恢复和水土保持规划建设，项目“深圳市水土保持科技示范园”去年还捧获IFLA奖项。而SWA集团也在基础设施领域有着多年的研究和实践。去年，《景观基础设施：SWA个案研究》结集出版。在实际工作中，存在哪些关键的困难挑战？有哪些经验值得积累？

何昉：深圳市水土保持科技示范园现在已成为水利部在全国范围内推广的典型和代表。这座风景式水保园之所以能被赋予某种示范性，我想，将中国城市水土保持与风景园林的优势进行开创性的融合，以一种学科交叉、科学理性的方式去回应城市环境改善的复杂要求，是这个项目的特殊价值所在。

城市本来是一个完整的生态系统，但是各自割据、部门割据，规划分离，难以形成整体，生态斑块破碎化、孤岛化。更加注重市政系统等灰色基础设施，绿地能挤压则挤压，让位于城市建设的发展，绿色基础设施难以形成网络和发挥作用，这已经严重影响到了人民生活水平和幸福感。

在近20年来快速城市化的过程中，忽视了生态环境，忽视了生物多样性，迫切需要从优化国土安全格局、优化城乡空间结构的基础上，更加注重区域生态环境、注重生物多样性，让人与动植物都能有尊严的活着。必须要给予绿色更多的空间，彻底进行规划战略的改变。这涉及到传统规划体系、土地利用规划等一系列的改良，需要进行深入的研究。

洪盈玉：《景观基础设施：SWA 个案研究》的成书在很大程度上受到了 2008 年在多伦多召开的一次研讨会的启发。在这次题为“景观基础设施 – 用以重塑现代城市景观的新兴实践、范例和技术”的研讨会上，学者、作家和实践者就这个课题以及它提升景观讨论层次的潜力交换了意见。

大多数研讨会参加者认为，规划和管理基础设施陈旧的城市需要全新的观念，而要实现充满活力和功能强大的21世纪城市就需要把基础设施当作重点。因此，我们写书的主要目的是延伸这个对话，通过评论文章和个案分析来讨论和重新定义基础设施。

格杜·阿基诺：我们开始对基础设施这个话题感兴趣，是因为我们发现城市中很多开敞空间本可以开发为公园、绿道等等，却被传统的基础设施如机场、油田、铁路站场、雨洪水渠、公路和停车场占据。虽然这些设施可以用来满足生活的基本需求，但是大多数只具备单一功能，而且有些只在高峰期发生作用 (例如雨洪水渠)。我们逐渐体会到，要解决城市热岛效应和创造舒适、可持续城市环境，就要改变这些基础设施系统的用途、甚至重新设计，使它们的功能效率更高，在同一时间提供多种用途，特别是在城市景观领域。

美国在传统上偏向设计单一功能的基础设施系统，在特定时期以最大的效率满足单一功能，但是在生命周期中不能持续地提供同一水平的效率。这样的单一方法给基础设施对城市生活的贡献带来严重的限制。停车场、交通走廊、公交转运中心和水渠在非高峰期处于闲置状态，在城市中形成空白和障碍。

我们面临的挑战是重新定义体系化的基础设施概念。我们需要有一个公开的讨论，即多个行业的人士 (风景园林师、规划师、工程师、建筑师、生态学家和房地产顾问) 如何参与基础设施的设计，使其满足多样化的功能。

《风景园林》：城镇化被视为未来中国经济发展的一大推动力，随之而来的大规模基础设施投资已然激发各地的积极性。如何才能避免之前由于忽视生态成本进行大开发所带来的环境恶果？

锁秀：我们认为，连贯密布的绿色基础设施网络将成为我国城乡空间与环境问题的系统化解决途径。目前，在中国城乡一体化背景下的绿色基础设施发展，应致力于强调城乡联系与结合，考虑低成本及干预效益最大化的必要性。绿色基础设施的战略提议应与当地的空间规划和开发管理结合起来，同时通过一些非空间项目和教育项目的支持，着眼于影响城乡居民的可持续生活模式。

对自然的崇尚、对人居环境和生态文明发展的重新审视，是我们绿色基础设施共享的理念和出发点。我们北林苑基于近年持续跟进的广东绿道规划设计工作，将研究视角拓展到珠三角园林城市群乃至广东省城乡大生态大景观系统，其核心是将快速发展的城镇化进程中岌岌可危的生态环境、支离破碎的社会构成和迅速多变的生产方式联系起来，突破传统规划的局限，将自然演进和城市发展整合为一个可持续的人工自然系统。在新型城镇化道路中，北林苑始终致力于成为引领绿色基础设施在大都市城乡区域实现全覆盖规划设计理念的实践先行者。

洪盈玉: 农业景观有可能被定义在绿色基础设施之内。农业土地本身已经承担重要的生产任务，因此要成为多功能景观就需要高度强化其功能。这意味着土地的农业景观身份需要扩展，其功能必须超越耕作而承担另一种功能，如作为与其他社区相连的连接网络。

以上海的崇明岛北湖地区总体规划为例。上海市政府将北湖地区的土地功能划为生态敏感农业、生态旅游和策略开放空间保留地。在这种土地使用条件之下，SWA 的规划采用的景观恢复策略，一方面恢复和提升退化的生态系统，一方面启动一系列实施措施，解决大型景观改良项目带来的经济问题。这一框架提供愿景，让开发商、政府官员、设计者和规划者在高度有效的景观中创造开敞空间、增加农业产出和解决环境问题。

《风景园林》：风景园林师是否会承担比以往更大的社会责任？

格杜·阿基诺：在公路、公交和其他基础设施项目中，工程师如果不是唯一的、往往也是主要的顾问。风景园林师的角色是争取参与项目启动之前的决策过程。这包括与决定项目最终效果的公交和政府机构、工程师和规划师沟通。通过与这些方面的合作，风景园林师可以帮助减轻这些大型侵略性结构的冲击。早期的沟通有助于我们思考如何在项目中创造开放空间和生态可行性。

何昉：我十分赞同格杜·阿基诺先生的观点。从2009年开始至今的广东绿道网规划设计工作，是城市规划、风景园林共同主导和各专业工程师合作式规划设计的典范，也是鼓励公众、专家和政府官员同时介入的项目运作典范。这对今后广东省从绿道到绿色基础设施网络全覆盖的规划构建起到了非常好的借鉴作用。尤其是绿色基础设施的规划建设，基于对传统灰色基础设施作用、成本和规划建设的理解，基于对“网络中心”和“连接廊道”的评估和选择，以及对雨水花园、绿色屋顶、雨洪设施、绿色家庭等“工程措施”新技术的创新应用，都使得风景园林专业需要不断的充实各层面的知识体系，以更加专业的职业道德承担起自己的社会责任。

最近蔡瀛副厅长在澳门国际环保合作发展论坛和我本人在美国刚刚召开的国际绿道大会上对广东绿道成就和绿色基础设施的推动做主题发言，得到国际学者一致好评，美国绿道权威法布士和埃亨教授寄语广东绿道和绿色基础设施建设作出更大的成就和成为国际典范。在中国国家主席习近平上任首访来深圳及广东，希望这里成为全国改革和发展走在最前面的地区的今天，我们的任务更重了，我们将继续努力。（完）

 

LA: Recently, Premier Li delivered a speech of “Establishing a Modern China with Ecological Civilization”, holding that China will optimize the development pattern of national land space to form reasonable production space, living space and ecological space. How do you understand the functions and significances of green infrastructure under such background of the new era?

Gerdo Aquino: Landscape infrastructure offers the next step for further inquiry as a city’s development and economic future is in direct proportion to its ability to collect, exchange, distribute goods and services, resources, knowledge, and people across vast territories. Chinese Government has said that the development in the 21st century will be focused on ecological sustainability, which means that green infrastructure theory will be considered in future planning process. The more the urban population increases, the more precious open space and nature will be. It is clear that green infrastructure theory can make our cities more efficient in its use of land, more sustainable in its use of resources, and more literate in educating a new generation of global citizens to understand and nurture our public realm.

He Fang: To embody the idea of respect for nature in national strategies is the inheritance and development of Chinese culture and tradition. It is both improper to emphasize only ecological environment protection or urban development. With such rapid urbanization, China’s urban construction is irreversible. Prices must be paid if we want to turn construction areas back to natural landscape. However, as a city’s “life support”, green infrastructure provides a new development pattern for urban space form. Therefore, much attention must be paid to its foundational function, and its planning and implementation should be promoted in national strategies.

LA: As a positive strategy of creating a win-win development between nature and human beings, green infrastructure has been experiencing a long process of its promotion and development. Can you talk about the situation of its development in China and in the U.S.?

Ying-yu Hung: Let me say something about its development in America. “Landscape infrastructure” is a term formulated by Pierre Belanger, who has helped shape the pedagogy and practice of this theory. His academic subjects have been accepted in Landscape Planning and Design Course in academies and universities such as Harvard Graduate School of Design, University of Texas at Austin and University of Pennsylvania.

As the world faces an urgent need for new and repaired infrastructure systems, design and planning professionals have the crucial opportunity to reimagine networks that support multiple uses and functions. For example, America’s infrastructure is decaying at an astonishing rate. The U.S. Interstate system alone is over 80 years old and crumbling under the stress of increased usage. As traditional single-use systems, these highways and their counterparts-aqueducts and railways-have slowly run their course and have become obsolete in their ability to sustain their initial carrying capacities as well as the structural systems that support them. This raises the question; Can landscape itself be considered an infrastructure in the sense that it could also act as a kind of conveyance or distribution network?

Gerdo Aquino: In fact, green infrastructure theory is gradually accepted by government agencies, which are assessing its current abilities to evaluate its survival ability and its ability to fulfill future needs. For example, since the mid 1980s, supporters of Buffalo Bayou have been longing for the restoration of the natural system corridor located in Huston, Texas. They demonstrated a series of action plans, trying to reconstruct some portion of the corridor in advance to set an example for the rest of the reconstruction. And landscape architects and engineers also developed a series of particular design approaches to make the corridor become public space again.

From 2007 to 2012, the City of Los Angeles have been researching on the ecological and recreational function potentials of the city’s water channels on condition that stormwater should be released in to sea as soon as possible. In Los Angeles, the average peak flow of the city’s rivers, including the 14.5km Baiona Stream Corridor, reaches 107m3/s. In March 2013, Los Angeles City Council voted to push a trial proposition, setting one portion of the city water channel a four-month recreational entertainment corridor. This temporary project allows access to the original restricted areas for residents, and is a significant attempt to integrate landscape infrastructure theory into public policy.

He Fang: Shenzhen is the pioneer in pushing China’s green infrastructure development. In the 1980s, Shenzhen’s early city planning was already laying stress on the pattern of urban green space system. Cities are distributed on flat areas in group structure with an 800-1000m wide ecological corridor among groups, forming an ecological structure of cities being surrounded by green space. After 30 years of development, the ecological corridors are now the ecological parks network in cities. In November, 2005, the Shenzhen city defined an ecological control line based on the ecological green space system of the 8 large-scale region’s green space and 18 urban ecological corridors, which was China’s first urban ecological protection control line. Despite the development limits of the time, the control line found its way to keep a balance between green space protection and urban development.

Moreover, Shenzhen’s involvement in the PRD greenway network planning and construction in recent years also won the “2011 China Habitat Environment Model Award” and the title for the top 100 practices of the “2012 Dubai International Award for Best Practices to Improve the Living Environment”, while the Guangdong Greenway Network Planning, the Capital-round Greenway Network Planning, and the greenway movements in Beijing, Guangdong, Guangxi, Jiangsu, Anhui, Sichuan and Hunan are still in the ascendant. In my opinion, Guangdong has been in the frontier of green infrastructure development, and the Department of Housing and Urban-Rural Development of Guangdong Province has been promoting this significant project.

In addition, as the world’s first Landscape Urbanism practice, Shenzhen Qianhai planning and construction has implemented the work of planning and design of green infrastructure coverage. As Shenzhen and Zhuhai are taking the lead in the action, it is not far to realize a complete coverage of green infrastructure in Guangdong.

LA: Let’s go further on the topic. As we know, Mr. He, BLY has been involved in the green way planning and construction of the Pearl River Delta, and is the pioneer in a national-wide exploration of urban ecological restoration and water and soil conservation planning and construction. Its project “Shenzhen Soil and Water Conservation Park” also won IFLA prize last year. As for the SWA group, they have had years of research and practice experience in the field of infrastructure and last year, Landscape Infrastructure: Case Studies by SWA was published. Can you point out the challenges during your work and what can we learn from it?

He Fang: Shenzhen Soil and Water Conservation Park has become a national-wide model promoted by Ministry of Water Resources. One of the significances of this park is the combination of the soil and water conservation and the advantages of landscape architecture, addressing the complexities of urban environmental improvement in a multidisciplinary and scientific way.

A city was originally a complete ecosystem. However, the separations and planning isolations has led to fragmentation and islanding of ecological patches. More attentions has been paid to grey infrastructure instead of green space, and green infrastructure has given way to urban construction, preventing itself from functioning and forming a network, which has caused negative effects on people’s quality of life.

In the rapid urbanization process of the last 20 years, ecological environment and biodiversity have been ignored. Therefore, measurements must be made to optimize land security pattern and urban-rural space pattern, and more spaces must be spared for “green”. Traditional planning system and land use planning system have to be improved to address the issue.

Ying-yu Hung: Landscape Infrastructure: Case Studies by SWA drew substantial inspiration from a symposium held at the University of Toronto in 2008, called “Landscape Infrastructures- Emerging Practices, Paradigms and Technologies Reshaping the Contemporary Urban Landscape,” in which academics, writers, and practitioners shared their views on this topic and its potential to heighten the polemics of landscape.

The symposium participants overwhelmingly argued that a fresh point of view is needed to plan and manage cities with outdated infrastructure and that a focus on infrastructure is the key to a more vibrant and functional 21st-century city. Therefore, the main goal of this publication was to continue this dialogue by engaging and redefining infrastructure through critical essays and case study projects.

Gerdo Aquino: The curiosity about infrastructure stemmed from our realization that the city we live in where there are opportunities for open space-parks, greenways and so forth-are taken over by infrastructure: airports, oil fields, rail yards, storm water channels, highways, and parking lots. Although these systems fulfill the basic necessity of our lives, most of them are single purpose and some perform their intended functions only at peak hours (i.e. storm water channels). It became obvious that the solution to address the urban heat island effect and the creation of comfortable, sustainable urban environments lies in the ability to repurpose, and perhaps redesign these infrastructural systems so that they may perform at a higher efficiency-accommodating multiple uses at the same time, particularly in the realm of urban landscape.

Traditionally the U.S. tends to design infrastructure system with single function, meeting a single need with highest efficiency in a particular period but failing to maintain the same level of efficiency in its life circle. Such single-functioned design largely limits the infrastructure’s contribution to the city, for example, parking lots, traffic corridors, public transit centers and water tunnels will remain unused during off-peak period, becoming a blank and obstacles in the city.

The challenge we are facing is redefining the systemic infrastructure concept. We need to hold an open discussion about how professionals from multi-industries (landscape architects, engineers, architects, ecologists and real estate consultants, etc.) should participate in infrastructure design to fulfill its multiple functions.

LA: Urbanization is considered as the major driving force for China’s future economic development. With it comes the large scale investment and enthusiasm in constructing infrastructures in multiple places. How do we avoid environmental disruption caused by the large-scale development and the ignorance of the ecological cost?

Suo Xiu: In our opinion, a coherent and intensive green infrastructure network would be the solution to China’s systemization of urban-rural space and environment problems. The green infrastructure development in China’s urban-rural integration should focus on the urban and rural communication and combination, and consider for the necessity of maximizing the cost efficiency and intervention efficiency. At the same time, green infrastructure strategy should combine with local space planning and development management, realizing a sustainable living pattern for urban and rural residents through a series of non-space projects and educational projects.

Admiring for nature and re-studying the development of human settlements and ecological civilization are green infrastructure’s concept and starting point. Based on the continuous involvements of Guangdong greenway planning and design in recent years, BLY has expanded its research vision to garden cities in the PRD areas and Guandong’s urban and rural grand ecological landscape system. Its core is to connect the endangered ecological environment, social construction with the changeable production mode to break through the limits of conventional planning, integrating nature and urban development into a sustainable artificial nature system. BLY has always been, under the new path of urbanization, devoting itself to become a pioneer in leading the practice of the planning and design concept of realizing a complete coverage of green infrastructure in metropolis’s urban and rural areas.

Ying-yu Hung: Agricultural landscape can be included in landscape infrastructure’s concept. Agricultural land has been undertaking the important task of food production. Therefore, to make agricultural land become multi-functional landscape, measures should be made to intensify its functions highly. This means expansion of its role of being agricultural landscape, and surpassing of its farming function to undertake other functions such as being a connective network for other communities.

Taking the master plan of “New Terrain for the North Lake Region of Chongming Island” as an example, the Shanghai Government defines the land function of the North Lake region as ecological sensitive agriculture, ecological tourism and strategic open space reservation. Under such land use condition, SWA’s plan adopted a landscape restoration strategy, restoring and improving the degraded ecosystem and launching a series of measurements to address the economic problems caused by large-scale landscape improving projects. SWA’s framework provides visions for developers, officials, designers and planners to create open space, increase agricultural output and solve environmental problems in highly effective landscapes.

LA: Will landscape architects undertake larger social responsibility in the future?

Gerdo Aquino: In road construction, public transportation construction and other infrastructure projects, engineers, if not the only one, are often the main consultants. And the role that landscape architects play is to endeavor to be one of the decision makers before the initiation of projects. This includes communication with public transportation agencies and governmental institutes, engineers and planners, who can decide the final effects of the projects. And with such cooperation, landscape architects can help reducing the impacts of those large aggressive structures. Early communications do help us consider how to create open space and the ecological feasibility in various projects.

He Fang: I agree with what Mr. Gerdo says. Since 2009, the efforts of Guangodng greenway network planning and design have been the model for multidisciplinary cooperative planning and design held by urban planning and landscape architecture, it is also an example for encouraging interventions of the public, professionals and government into projects, which will be a guidance for future engagement of green infrastructure coverage planning and construction in Guangdong. The green infrastructure planning and construction requires enrichment of the landscape architecture discipline due to its contribution to grey infrastructure, understanding of cost and planning and construction, the assessment and selection of the “network center” and “connective corridor”, and the innovative applications of rain gardens, green roofs, stormwater facilities and green families, etc.

Recently, Cai Ying’s speech in Macao International Environmental Co-operation Forum about Guangdong’s achievement in greenway and the promotion of green infrastructure, as well as mine in International Conference on Greenway won praise from international scholars. Julius Fabos and Professor Ahern also delivered their recognition for Guangdong’s green infrastructure construction. As President Xi paid his first visit to Shenzhen and expressed his wishes for future development and reform, more responsibilities have been laid on our shoulders, and we will keep working hard to make Shenzhen a more beautiful city to live in.(The end)
