Ecological Protection and Restoration Zoning in Land Space of Mountainous Urban:A Case Study of Chongqing
Delineating ecological protection and restoration areas scientifically is the basis of national spatial ecological protection and restoration planning,and it is also the main basis for formulating differentiated ecological protection and restoration policies.Taking Chongqing as an example,this paper focused on the protection and restoration of territorial space ecology and the practical needs of human activities.Based on a comprehensive analysis of the current situation of territorial space ecology and the evaluation of its ecological function status,the study explored the methods and ideas for partitioning the protection and restoration of territorial space ecology,following the natural geographical pattern and the integrity of ecosystems.Research shows:(1)The natural resourc-es such as mountains and water naturally divide the entire city into two basic spatial areas.The first is a natural ecological space dominated by Daba Mountain,Wushan-Qiyao Mountain,Wuling Mountain,and Dalou Mountain.This area is rich in natural re-sources and has outstanding ecological functions.The second is a human activity space dominated by parallel ridges and valleys and square hills and mountains.This area has flat terrain and good farming conditions,making it the main urban construction area and agricultural development area.(2)The human activity intensity is low,the ecological sensitivity is high,and the service func-tion level is relatively high in the peripheral mountainous areas and high-altitude mountain ranges.The degradation is not obvious,and the resilience is at a high level.In contrast,the central urban area and western Chongqing region have strong human activities,significant ecosystem degradation,lower service function levels,and weak resilience.(3)Based on the differences in ecological sta-tus and ecosystem conditions,considering the combined natural,social,and economic needs,this paper proposed a"One Core and Four Zones"ecological protection and restoration zoning.Additionally,it put forward some suggestions for the direction of ecologi-cal protection and restoration governance for each zone.
