基于MSPA与MCR模型的景观生态网络构建与优化
Construction and Optimization of Landscape Ecological Network Based on MSPA and MCR Models
摘要
Abstract
Human activities have greatly changed the original land use structure,ecosystem functions and ecological pattern.The continuous development and utilization of land,the expansion of urban boundaries and the blind pursuit of economic development have seriously affected the ecological bal-ance and the stability of ecological regions.In this paper,land use data of Baoji city,combined with models and methods such as MSPA model,MCR model and circuit theory,were used to con-struct and optimize the ecological network in the study area.The results showed that 26 ecological source areas were identified,mainly distributed in the forest areas in the northeast,west and south of Baoji city,and 2 core ecological source areas were identified,all of which were located in the mountainous area of Qinling Nature Reserve.The identification of 67 ecological corridors can help restore ecosystem service functions;Construct a 5-level ecological buffer zone according to the mini-mum cumulative resistance value to improve the quality of ecological environment.According to the conclusion of the final results,the constructive ecological network optimization measures are put for-ward,which can improve the ecological environment quality and ecological regional security more ef-fectively.关键词
