城市高度建成区生态修复策略研究——以重庆市渝中区为例

Research on Ecological Restoration Strategies of Highly Built-up Areas in Cities——Taking Yuzhong District,Chongqing City as an Example

城市高度建成区是我国城市不断扩张的结果,具有人口密集、建筑密度大、基础设施较为完善等特点;但城市绿地空间不断缩小、生态功能持续退化、热岛效应、大气污染等问题也日趋严重,制约着城市可持续发展。以渝中区为例,在深剖其主要生态环境问题的基础上,提出了渝中区生态保护修复工作应从加强区内自然山水重要生态资源保护修复、多渠道拓展绿化空间、完善生态网络系统、深化污染物和碳减排力度等方面入手,可为渝中区生态宜居城市建设提供参考借鉴。

Highly built-up urban areas are the result of the continuous expansion of cities in China,with dense population,high building density and relatively perfect infrastructure.However,urban green space is shrinking;ecological functions are deteriorating;heat island effect and air pollution are becoming more and more serious, which restricts the sustainable development of cities. Taking Yuzhong District as an example, based on deep analysis of its main ecological and environmental problems, this paper puts forward that the ecological protection and restoration work in Yuzhong District should strengthen the protection and restoration of important ecological resources of natural landscapes, expand the green space through multiple channels, improve the ecological network systems, and deepen the emission reduction of pollutants and carbon, which is expected to provide reference for the construction of ecologically livable cities in Yuzhong District.
