摘要
在估算土壤侵蚀量、编制土层厚度图和土壤容重图的基础上,利用地理信息系统的空间分析功能估算土壤的抗蚀年限,从而有效地实现对济南市山丘区土壤侵蚀危险度的分级;借助GIS方法,通过分析不同坡度、不同坡向、不同地貌类型以及不同土地利用类型等背景条件下的土壤侵蚀潜在危险度状况,探讨土壤侵蚀潜在危险度的空间分布特点。
Taking Jinan mountain area as an example, on basis of estimating soil erosion modulus , compiling maps of soil horizon thickness and soil density, using overlapping function of geographical information system(GIS) to estimate the years of soil loss by erosion, gradating the potential danger of soil erosion is easy to be done. By using GIS, the authors analysed the soil erosion potential danger under different erosion background such as different slope, different aspect, different geomorphology type, etc., and thus discussed the distribution characteristics of soil erosion potential danger .
