Identification of Key Areas for Ecological Protection and Restoration Based on Circuit Theory:A Case Study of Liangping District in Chongqing City
Taking Liangping District,Chongqing City as the research object,the paper used morphological spatial pattern analysis and circuit theory to identify key areas for ecological protection and restoration,including ecological source areas,ecological pinch points,ecological obstacle points,and ecological rupture points.The re-sults show that:(1)There are 19 ecological source areas in the study area,with a total area of 359.82 km2,show-ing a spatial distribution feature of"two belts and multiple points";There are 42 ecological corridors with a total length of 241.27 km,constructing an ecological security pattern of"three areas,three screens,one network,and multiple nodes";(2)Identifying 5 ecological pinch points,12 ecological obstacle points,and 5 ecological fracture points are key areas for ecological protection and restoration,mainly distributed in the central and eastern regions;(3)Based on the ecological characteristics of key areas,propose corresponding main directions and suggested measures for ecological protection and restoration.The research can provide a path and method reference for the ec-ological protection and restoration of land space in Liangping District and other regions.
