基于最小累积阻力模型的广西生态安全格局研究
Study on the Ecological Security Pattern in Guangxi Based on Minimum Cumulative Resistance Model
摘要
Abstract
The construction of ecological security pattern is an important guarantee for the scientific planning and utilization of ecological space.In this study,Guangxi was taken as the research area,and the ecological source was identified based on the importance evaluation of ecological protection.The Minimum Cumulative Resistance(MCR)model and the gravity model were used to extract ecological corridors and ecological nodes.On this basis,the ecological security pattern was constructed and optimized.The research results indi-cate:① The area of moderate and above level of ecological protection importance in Guangxi is 133 582.64 km2,accounting for 56.22%of the land area of Guangxi.Moreover,the importance level of eco-logical protection in Guangxi is generally lower in the northwest,south and central regions,and higher in the southwest and northeast.②The ecological security pattern of Guangxi is composed of 18 ecological sources,44 ecological corridors and 348 ecological nodes.Based on the above results,the areas that can be targeted for construction and maintenance are divided,and suggestions for protection measures are proposed.The research results of this study can provide scientific basis for promoting the stability of the ecological security pattern in Guangxi.关键词
