| Tiivistelmä: | The soil erosion of the loess plateau is the main source of the sediment of the Yellow River. The calamitous loss of soil and water is the concentrated reflection of eco-environment weakness and has being effected by human activities. Applying several statistical methods including cluster analysis, step wise regression and mononization of multiple variers, we have some research on the problem that which is the main reason of the soil erosion natural erosion or human accelerated erosion. We draw conclusions that under various environment the effect degrees of human activities are not the same, and compared in the whole region, the effect degree of human activities is smaller than the natural. |
