摘  要：
依据第三次水土保持遥感调查成果和全国水利普查水土保持普查成果,引入水土流失严重指数概念,对新疆水土流失现状进行了分析评价。在此基础上,对这2次水土流失数据进行对比分析,结果发现:新疆水土流失总面积有所下降,但水土流失强度呈加剧趋势,水土流失问题依然严峻;水土流失面积变化区域差异明显,呈现"北增南减"的特点;新疆重点矿产资源开发区的水土流失危害呈明显加剧趋势。

摘  要：
This paper analyzed the present situation of soil loss in Xinjiang,which are based on the "soil and water conservation remote sensing survey results for the third time " and the "soil and water conservation data in the national water resources census survey ". Meanwhile,a concept of soil loss severity index is proposed in this paper to evaluate the severity of soil and water loss in Xinjiang. Further more,by contrasting the data of soil loss in 2000 and 2012 of Xinjiang,we have come to the tentative conclusions: the soil loss area are increased in Xinjiang,but the intensity showed a rising trend;Regional differences are obvious for alteration of soil loss area in Xinjiang, which shows the characteristics of "increases in the northern and decreases in the southern "; Soil erosion hazard intensified trend is obvious in the main mineral resources development zone.
