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(14442.4) 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.
