【摘要】 根据"确定生态源地-构建生态阻力面-分析中心度、生态廊道、夹点、障碍区"三个研究步骤,构建东至县生态安全格局,进而提出相应的生态保护修复策略。研究发现:研究区范围内生态源地共95个,面积共计4 114 km~2;县域内生态廊道共72条,共计115.84 km。研究识别出研究区内中心生态源地22个,中心生态廊道11条;县域内生态"夹点"31处,生态障碍区16处。文章结合生态安全格局、土地利用现状,针对不同区域提出生态修复方案,期待研究结果可为东至县及相似地区的生态保护与修复提供一些参考。更多还原

【Abstract】 According to the three research steps of determining the ecological source area, constructing the ecological resistance surface, and analyzing the centrality, ecological corridor, pinch points and barrier areas, this paper constructs the ecological security pattern of Dongzhi County, and then puts forward the corresponding ecological protection and restoration strategies. The results show that there are 95 ecological source areas in the study area, with a total area of 4 114 km~2, and 72 ecological corridors, with a total of 115.84 km. The study identifies 22 central ecological source areas and 11 central ecological corridors, 31 ecological pinch points and 16 ecological barrier areas in the study area. Based on the ecological security pattern and the status quo of land use, the ecological restoration schemes are proposed for different regions. The results can provide reference for ecological protection and restoration in Dongzhi County and similar areas.更多还原
