深圳市福田区建成绿道网络评价

Evaluation on Built Greenway Network in Futian District,Shenzhen

绿道网络建设已成为城市生态文明建设和发展的焦点,而绿道网络综合评价是绿道网络提升的重要环节和关键过程。深圳市是中国第一批建设绿道的城市,在绿道建成10年后进行综合评价研究,对于城市绿道网络品质提升具有重要意义。基于国内外相关研究及实地调研,从城市绿道基本功能、空间品质和系统连接3个维度,构建深圳市福田区的城市绿道综合评价体系,对已建成绿道进行综合评价。结果表明:福田区绿道系统可达性较高,但整体通畅度不佳,基本功能有待完善;绿道整体安全性较低,使用体验有待改善,空间品质有待提升;绿道对于城市重要开放空间及文化节点设施的连接度不够,主题不够鲜明,未能作为文化承载媒介发挥效益;空间分布上相对集中在中心城区,且多以绿道连接线的形式出现,正线建设比例较低,系统整体运行效率不高。基于评价结果提出:1)需强化绿道骨干网络,加强紧密连接群众生活的社区级绿道以及公交微枢纽的绿道建设,提升绿道系统整体运行效率;2)注重绿道设计的空间体验;3)加强绿道与自然、文化、生活的连接融合,充分发挥绿道系统的复合功能,为未来福田区乃至深圳市的绿道网络提升提供理论参考。

Greenway network construction has become the focus of urban ecological civilization construction and development,while comprehensive evaluation of greenway network is an important linkage and key process of greenway planning and construction.Shenzhen is one of the first cities building greenways in China.For greenways in Shenzhen that have been operating for 10 years,conducting a comprehensive evaluation and research is of great significance to improve the greenway network of the whole city.Based on relevant researches and field investigations home and abroad,this research,from the three dimensions of basic functions,spatial quality and systematic connectivity of urban greenway,builds a comprehensive evaluation system for urban greenways in Futian District,Shenzhen for conduction on existing greenways therein.The results show that the greenway network in Futian District has high accessibility but poor overall access smoothness,entailing further improvement of basic functions;the overall safety of greenway is quite low,and the usage experience thereof quite poor and spatial quality awaiting improvement with insufficient connection with major open spaces and cultural nodes in the city and indistinct themes,the greenways therein fail to well play the role of cultural carrier.In terms of spatial distribution,the greenways are mainly distributed in the central urban area and mostly in the form of greenway connection line,leading to lower proportion of main line construction and inefficient operation of the overall greenway system.Based on the aforesaid evaluation,the research makes the following suggestions:1)strengthen the backbone network of greenways and the construction of community-level greenways closely connected with people’s life and greenways accessible to public transit micro-hubs,so as to improve the overall operation efficiency of the greenway system;2)emphasize the space experience of greenway design;3)strengthen the integration of greenways with nature,culture and life,and give full play to the composite functions of the greenway system,with a view to providing theoretical reference for future improvement of greenway network in Futian District and even Shenzhen as a whole.
