城市生态网络构建与优化——以徐州市为例

Construction and Optimization of Urban Area Ecological Network

城市生态用地在城市化推进过程中被大量占用并转化为建设用地,导致生态网络结构不断重塑。为了在有限的土地上更好地提升城市生态环境质量,有必要对城市生态网络进行结构上的剖析,用于指导城市生态网络的优化。该文以典型城市徐州市主城区为研究对象,通过生态源地识别、生态廊道构建的方式对其生态网络结构进行深入研究并展开评价,以把握徐州市主城区生态建设的方向和重点,并为相关城市的生态建设思路提供借鉴。

The ecological land in city is largely occupied and transformed into land for construction in the process of urbanization,resulting in the continuous reshaping of the ecological network structure.In order to better enhance the quality of urban ecological environment in the limited land,it is necessary to analyze the structure of urban ecological network so as to guide the network optimization.Taking the main urban area of Xuzhou as the research object,this paper made an in-depth research and evaluation on its ecological network structure by way of ecological source identification and ecological corridor construction,in hope of grasping the direction and focus of ecological construction in the main urban area of Xuzhou,and providing reference for the thinking of ecological construction in relevant cities.
