摘要
利用国情监测成果，分析了2010~2014年秦岭山地丹江流域土地利用类型变化特征，并探讨了土地利用类型方式转变对流域土壤侵蚀的影响。结果表明，微度侵蚀和轻度侵蚀面积在波动中呈减少趋势；中度侵蚀至剧烈侵蚀面积呈上升趋势，在一定程度上，流域的侵蚀状况加剧。土壤侵蚀较严重的土地利用类型是耕地和裸地。
Using the results of geographical conditions monitoring, this paper analyzed the land use change features of Qinling Mountains Dan River Basin form 2010 to 2014. And then, the paper investigated the effect of land use changes for soil erosion. The results show that slight erosion and erosion tended decrease slightly in fluctuation, and moderate erosion to severe erosion are rising. To a certain extent, Dan River Basin's erosion is increasing. The cultivated land and bare land's soil erosion are serious.
