【目的】艾比湖区域土壤侵蚀特征分析。【方法】采用3S(RS、GIS、GPS)技术手段,根据新疆艾比湖区域2007年(TM)遥感影像、2006年DEM数据,综合多年气象数据、土壤类型等资料,裁出同一坐标投影(WGS-1984-UTM-Zone-44N)下的研究区土壤侵蚀的四个主要因子(植被覆盖度、坡度、风速及土壤可蚀性k值)30 m×30 m的栅格图像,进行叠加分析得到研究区土壤侵蚀特征。【结果】研究区以中高侵蚀为主,其中中度侵蚀面积最多,占总面积的56.58%;强度侵蚀次之,占总面积的25.87%;其它侵蚀强度分布面积从多到少依次为:轻度侵蚀8.43%,微度侵蚀5.91%,极强度3.15%,剧烈侵蚀分布面积最少,占总面积的0.06%。【结论】新疆艾比湖区域土壤侵蚀较为严重,但分布相对规律,对土壤侵蚀的防治与治理有着重要的作用。
【Objective】 The characteristics of soil erosion in the Aibi Lake area. 【Method】 Using 3S (RS, GIS, GPS) techniques, according to 2007 remote sensing images of Lake Aibi in Xinjiang, DEM data of 2006, comprehensive meteorological data and soil types, the same coordinate projection WGS-1984-UTM-Zone-44N), a 30 m × 30 m grid image of the four main factors of soil erosion (vegetation cover, slope, wind speed and soil erodibility) Get the characteristics of soil erosion in the study area. 【Result】 The study area is dominated by medium and high erosions, of which the moderately eroded area is the most, accounting for 56.58% of the total area; the second is the intensity erosion, accounting for 25.87% of the total area; the others are as follows: light The degree of erosion is 8.43%, the degree of micro-erosion is 5.91%, the maximum intensity is 3.15%. The area of severe erosion distribution is the least, accounting for 0.06% of the total area. 【Conclusion】 The soil erosion in Aibi Lake region in Xinjiang is more serious, but the relative law of distribution has an important role in the prevention and control of soil erosion.
