| 摘 要： | 土壤可蚀性K值作为评价土壤特性的重要参数,是水土保持规划、土地利用评价、水土保持综合治理工程等规划设计工作中的重要基础数据。笔者从贵州省五大石漠化治理类型区的空间角度出发,选择五个典型小流域作为研究对象,应用EPIC模型分析其土壤抗蚀性,探索不同类型石漠化土壤可蚀性的特征及差异,初步认为贵州省岩溶地区总体由北向南K值逐渐增大,峰丛洼地石漠化类型区土壤可蚀性最大,土壤最易侵蚀。

| Abstract: | The soil erodibility (K-Factor) as an important parameter of evaluating soil characteristics, soil and water conservation planning, land-use evaluation, comprehensive control of soil and water conservation engineering planning and design work of the important basic data.?The article choose five represent karst catchment as the research object form different project types rocky-desertification of space angle in Guizhou province.Using the model of EPIC analysis of the soil erodibility,explore the characteristics and differences with the different types
rocky-desertification.At the same time,in order to provide certain theoretical basis for the design and management process of soil erosion comprehensive control project,desertification control project in Guizhou province. |
