基于GIS与Fragstats的安徽省生态安全格局研究

Research on Ecological Security Pattern of Anhui Province Based on GIS and Fragstats

从区域生态安全重要性和敏感性角度出发,结合景观生态指数,构建安徽省生态安全格局评估指标体系,绘制安徽省生态安全格局图。结果表明:安徽省生态安全格局总面积为41083.46 km^2,占全省面积的29.53%,主体部分以大别山生态屏障和黄山生态屏障为支撑,总面积为30883.63 km^2,长江干流水生态廊道为屏障链接,巢湖等其他湖泊湿地为生态格局重要组成成分,总面积为1130.74 km^2。

Combined with the landscape ecological index,the assessment index system of ecological security pattern in Anhui Province was constructed from the perspective of ecological safety importance and sensitivity.On the basis of the above research,the ecological security pattern map of Anhui Province was drawn.The results show that the total area of ecological security pattern in Anhui Province is 41083.46 km^2,accounting for 29.53%of the province’s total area.The main part is supported by the Dabie Mountain Ecological Barrier and the Huangshan Ecological Barrier,with a total area of 30883.63 km^2.The barrier link is the Yangtze River mainstream water ecological corridor,and the important components of the ecological pattern are others lakes and wetlands such as Chaohu,with the total area is 1130.74 km^2.
