| 摘 要： | 分析了青海省三江源区草地生态系统土壤侵蚀的空间差异,以及草地退化与土壤侵蚀的关系,并对该区近30年来土壤侵蚀的动念变化进行描述.结果表明,该区域微度以上土壤侵蚀面积占源区总面积的46.47%,而草地生态系统发生微度以上土壤侵蚀的面积比例达56.04%.源区土壤侵蚀类型是以冻融侵蚀伴随着水力侵蚀或风力侵蚀的复合侵蚀为主,...

| Abstract: | Sanjiangyuan Region,as the headwaters of the Yellow River,Yangtze River and Lancang River,is known as China's Water Tower.In recent several decades,continuously grassland ecosystem degradation and soil erosion in the region were increasingly serious due to natural and human activities such as global warming,overgrazing,mining etc.Currently,the degradation of grassland ecosystem has attracted attention worldwide.Therefore,the spatial and temporal patterns of soil erosion in the region were beneficial to prov... |
