基于CSLE与GIS的高州市土壤侵蚀特征研究

Characteristics of Soil Erosion in Gaozhou City Based on CSLE and GIS

文章应用中国土壤流失方程(CSLE)与GIS地理空间分析技术,分析研究了高州市土壤侵蚀空间分布特征及其与土地利用之间的关系。研究结果显示:高州市土壤侵蚀以轻度自然侵蚀为主,主要分布在中部及北部,少量生产建设项目人为水土流失零星分布于南部城镇区域,不同强度的土壤侵蚀大部分发生在园地及林地,其次为耕地和建设用地;研究成果可为高州市进行水土保持规划、合理开发利用水土资源提供决策参考。

Using the Chinese Soil erosion Equation(CSLE)and GIS geospatial analysis technology,the spatial distribution characteristics of soil erosionand its relationship with land use in Gaozhou City were studied.The results show that the soil erosion in Gaozhou city is mainly mild natural erosion,which is mainly distributed in the central and northern parts of the city,and a small amount of man-made soil erosion in production and construction projects is scattered in the southern urban area.Most of the soil erosion with different erosion intensity occurred on garden land and forest land,followed by cultivated land and construction land.The research results can provide reference for decision making of water and soil conservation planning and rational development and utilization of water and soil resources in Gaozhou City.
