摘要: 在转型发展压力下,资源枯竭型城市仍将面临一定的生态退化风险,其生态保护修复面临严峻挑战。本文以江西省大余县为研究区,识别全域生态退化风险及其空间特征,划分生态保护修复区类型,并提出相应生态保护修复策略。研究结果表明:①大余县生态退化风险空间集聚特征显著,呈现“四片一带”的空间格局;②全县生态退化风险总体较低,局部生态退化风险主要源于生态压力,其中矿业开采是导致局部生态压力升高的关键因素;③将全县划分为生态治理区、生态涵养区、生态保育区和生态提升区,并采取差异化生态保护修复策略,有利于促进资源枯竭型城市国土空间生态保护修复的系统性推进。

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
