耦合生态系统服务和景观连通性的环塔里木盆地绿洲区生态安全格局研究
Ecological security pattern of the oasis area around the Tarim Basin based on coupled ecosystem services and landscape connectivity
摘要
Abstract
Ecological security plays an essential role in protecting biodiversity and maintaining ecosystem servic-es.However,current research on the construction of ecological security patterns has mostly focused on treating nature reserves as ecological sources while ignoring patches with potential ecological services and the impact of patch connectivity.Thus,an improved method of constructing ecological security patterns is proposed herein.In this study,the oasis area of the Tarim Basin Rim,south Xinjiang,China is taken as an example.Ecological source sites are optimized by coupling four ecosystem services,namely,carbon storage,water conservation,soil conser-vation,wind and sand control,and landscape connectivity.An integrated resistance surface is constructed and the ecological security pattern of the study area is determined using circuit theory.The results show the following.(1)The oasis area around the Tarim Basin was in a low-ecological-security zone,with water shortage and serious de-sertification in the region.(2)A total of 22 ecological sources with an area of 69622.24 km2 and 33 ecological cor-ridors with a length of 4722.39 km were identified in the Tarim Basin Rim oasis area,with the sources scattered in the south and densely sited in the north and with poor connectivity between the sources in the south and north.(3)An optimal layout plan for the ecological security pattern of"two screens,one ring,and multiple areas"was formed,ecological function zones were clarified,and the regional ecological environment was improved.This study can provide a reference for territorial spatial planning.关键词
