摘要
利用土壤普查成果中的土壤图和理化分析等资料 ,采用公式计算法研究了该区土壤的可蚀性K值 ,改进和完善了K值图编制方法 ,并用微机首次制出具有准确几何位置、可与地形图配准的土壤可蚀性K值图。同时 ,还依据该区K值的分布特点讨论了它在水土保持、土壤年流失量监测、生态农业建设和防洪减灾中的应用。
The soil erodibility ( K) value in this region was investigated with the formula calculation method, based on the physical and chemical properties of soil and soil map of the soil survey. In this study, a K value map well registered with the topographic map was made, in which accurate geographic positions could be located. Meanwhile, applications of the K value map in soil and water conservation, monitoring of soil loss, ecological agricultural construction and reducing floods were also discussed.
