滇西北剑湖双河水库流域不同土地利用类型下土壤理化性质及其对抗剪性能的影响
Soil Physical and Chemical Properties of Different Land Use Types and Its Influence on Shear Resistance in Jianhu Watershed of Northwestern Yunnan
[目的]通过对滇西北剑湖双河水库流域不同土地利用类型下的土壤理化性质和抗剪性能关系的研究,为研究区域及同类型的水土流失地区治理提供一定的依据和思路。[方法]以云南省大理州剑川县双河水库流域为研究区域,将研究区草地、林地、耕地和采矿用地 4种土地利用类型的土壤作为研究对象,根据当地干湿季节的土壤含水率,配置了三种实验含水率,分别对应旱季含水率 15%,雨季含水率 35%,和过渡季节的含水率 25%,并测定土样的理化性质和抗剪性能,分析不同土地利用类…查看全部>>
[Objective]Through the study of the relationship between soil physical and chemical properties and shear resistance under different land types,it provides certain basis and ideas for the control of soil and Moisture loss in study area and the management of the similar soil erosion area.[Method]Taking the Jianhu Moistureshed in Jianchuan County,Dali Prefecture,Yunnan Province as a typical study area,the four types of soils in the study area which are grasslan…查看全部>>
