| 摘 要： | 为建立土壤侵蚀动态变化数据库，本文以土地利用数据、植被覆盖指数、最大风速等值线图和DEM数据为信息源，对干旱荒漠区新疆克拉玛依市2000年和2007年的土壤侵蚀状况进行了动态监测与评价。结果表明，受自然条件和人类活动影响，8年间克拉玛依市土壤侵蚀强度有所增加，变化区域主要集中在克拉玛依市中部平原区。该方法的应用实现了土壤侵蚀的定时定量评价。

| Abstract: | For the establishment of soil erosion dynamic changes in the database, the paper studied dynamic monitoring and assessment of water and soil erosion from 2000 to 2007, in arid desertification area, in Kelamayi city Xinjiang province, based on the data of land use, DEM data and other relative assistant data. Result showed the erosion increased from 2000 to 2007 because of natural condition and eco- environment emigration. The changes of water and soil erosion mainly was happened the middle plains area in Kelamayi city. The method achieved the application of the soil erosion from time to time the quantitative evaluation. |
