| 摘 要： | 利用彰武县境内柳河所辖小流域2000年及2004年土壤风蚀遥感解译数据,分析了该区域土壤风蚀空间分布及时间变化特征。结果表明：2000年及2004年共有13条小流域土壤风蚀面积比例大于50%;2000年及2004年分别有17条小流域风蚀类型全部为轻度,其余为轻度与中度各占一定比例;总体上该区域风蚀面积比例呈下降趋势,风蚀程度呈减轻趋势。

| Abstract: | Spatial-temporal dynamic change feature of soil wind erosion were analyzed based on data of remote sensing interpretation of small watersheds in the Liu River in 2000 and 2004.The results showed the proportion of soil wind erosion areas in 13 watersheds in 2000 and 2004 were more than 50%.Seventeen watersheds in 2000 and 2004 were light soil wind erosion,light and moderate soil wind erosion existed simultaneously in the other watersheds.The proportion of soil wind erosion areas and extent of soil wind erosion were declined as a whole. |
