| 摘 要： | 用生态承载力和生态足迹理论,评价人类活动对生态环境的影响。分析和计算显示,黄土高原水土保持综合治理有效地增加了当地和下游引黄灌区的生态承载力。以2000年为例,黄土高原水土保持增加的生态承载力达1444.24万hm2,其中黄土高原当地约占77.74%,黄河下游灌区约占22.26%,说明水土保持对提高黄河流域生态(人口)承载力的重要作用,以及黄土高原在国家可持续发展战略中的重要地位。

| Abstract: | The influence of human activities on the ecological environment can be measured by the theory of ecological capacity and ecological footprint. With the development of soil and water conservation in Loess Plateau, the ecological capacity of the Yellow River Basin increased. The increased capacity is as much as 14 442.4 thousand hectares, 77.74% of the increased capacity is in the Loess Plateau itself, and the other 22.26 % is in the irrigation areas of the lower reaches of the Yellow River, which can prove the importance of soil and water conservation in Loess Plateau, and the importance of Loess Plateau to the sustainable development in China. |
