Ecological protection and restoration of resource-exhausted cities territorial space from ecological degradation risk perspective: taking Dayu county as an example

Abstract

Abstract: Under the background of transformation and development pressure and limited ecological resilience, resource-exhausted cities will still face certain risks of ecological degradation, and ecological protection and restoration will face severe challenges. The study takes Dayu county, Jiangxi province as the research area. It identifies the overall ecological degradation risk and its spatial characteristics, divides the types of ecological protection and restoration areas, and proposes ecological protection and restoration strategies. The research results show that:① Dayu county has significant spatial agglomeration characteristics of ecological degradation risks, showing a spatial pattern of "four areas and one area". ②The overall level of ecological degradation risk in the county is not high, and the local ecological degradation risk is mainly caused by ecological pressure, among which mining is the key factor leading to the increase of local ecological pressure. ③Dayu county is divided into ecological management areas, ecological conservation areas, ecological conservation areas and ecological improvement areas. The overall ecological protection and restoration should be carried out based on the characteristics of different regions to promote the systematic promotion of ecological protection and restoration of land space in resource-exhausted cities.

Key words: resource-exhausted cities, ecological protection and restoration, degradation risk, Dayu county
