摘要
文章基于从遥感影像中提取的DEM数据及水文气象数据,对伊犁的土壤侵蚀分布及强度进行分析得出:伊犁地区总体R因子平均值处于1600至5014之间,侵蚀力较低,坡度的平均值为20.65°,最大值为80.10°,最小值为0°。植被覆盖总体较高,平均值为0.65。对应的年均侵蚀量贡献根据最大、最小可分为剧烈侵蚀区域和强烈侵蚀区域。
Based on DEM data and hydrometeorological data extracted from remote sensing images,this paper analyzes the distribution and intensity of soil erosion in Yili,which shows that:the average value of R factor in Yili area is between 1600 and 5014,and the erosive force is low;the average value of slope is 20.65,the maximum value is 80.10,and the minimum value is 0,the vegetation cover is generally higher,and the average value is 0.65.According to the maximum and minimum contribution of annual average erosion amount,they can be divided into severe erosion area and intense erosion area.
