| 摘 要： | 以退化红壤地的朱溪河小流域为研究对象,利用GIS对不同高程带的土壤侵蚀特征进行分析.结果表明:无论从土壤侵蚀面积来看,还是从土壤侵蚀率和土壤侵蚀指数方面来看,土壤侵蚀都主要集中于海拔300～400m处,而在海拔450m以上较小.其原因主要是:在海拔300～400m处,较强烈的人为活动,容易使植被遭受破坏,加之坡度较大,加剧了土壤侵蚀的发生、发育和发展.随着海拔高度的增加,人类活动逐渐减少,土壤侵蚀也随之减少.

| Abstract: | This article takes the Zhu-xi watershed of Chang-ting as study area where red soil was severely degraded, using GIS techniques to analysis the soil erosion of degraded red soil with different elevation zone . The results show that :whether from the soil erosion area or from the soil erosion rate and index, soil erosion mainly located from the height of 300~400m but relatively small above 450m. In the high altitude of 300~400m, there are intensive human activities , vegetation destruction and good slope cond... |
