| 摘 要： | 为了解楚雄市尹家嘴水库流域近年来的水土流失情况，利用1：1万的地形图、卫星图片以及实地调查资料，将研究区分为28个小区，借助已有水文数据和通用水土流失方程（USLE）模拟计算了楚雄市尹家嘴水库水土流失总量。同时，按照国家水利部公布的水土流失强度标准，确定研究区的水土流失等级。结果表明：该区域属于轻度流失区，水土流失量也相对偏大，如果不加强治理和保护，那么该区域很快将转化为中度流失区。

| Abstract: | In order to learn the water and soil erosion of Yinjiazui Reservoir in Chuxiong city recent years.According the 1:10000 topographic map,satellite images and data of spot check.the study area was divided into 28 small areas,The total water and soil erosion of Yinjiazui Reservoir in Chuxiong City has been simulated with exist hydrological data and general erosion equation(USLE).At the same time,the levels of soil erosion of study area has been sured accord the national standards published by Ministry of Water Resources..The results showed that: the region belongs to the mild,and a large of amount water and soil erosion happened in region.,this region will be transformed into areas of moderate loss if the governance and protection have not to strengthen. |
