| 摘 要： | 利用生态足迹模型对南水北调中线工程实施前后的丹江口库区的生态足迹进行了计算和分析。结果表明:南水北调工程实施前,丹江口库区2007年人均生态足迹赤字为1.059 gha,库区整体上处于不可持续状态;与南水北调中线工程实施前相比,库区可利用的生态承载力减少了2.3%,生态赤字扩大了0.014 gha/cap;根据库区生态足迹和生态承载力计算结果,库区生态适度人口为122.8万人。

| Abstract: | The ecological footprint of Danjiangkou reservoir area before and after implementation of Middle Route of South-to-North Water Transfer Project is calculated and analyzed by ecological footprint model.The result demonstrates that Danjiangkou Reservoir in 2007 per capita ecological footprint deficit 1.059 gha,and the whole reservoir area is unsustainable before the implementation of Middle Route of South-to-North Water Transfer Project;the ecological carrying capacity of the reservoir area can be used reduce... |
