本研究根据在四川、云南等 4个评价区的实践 ,探索出一套实用于干旱山地土壤资源适宜性评价的简易方法 ,其主要评价依据是地面坡度、土层厚度、砾石含量、土壤养份含量等易于获取的因素。评价单元为地块 ,其划分方法为土地利用现状加地面坡度。评价方法采用“经验指数法”。用传统方法或GIS成图。本方法适用于移民安置区和专题规划区
Based on the practice of four evaluation areas in Sichuan and Yunnan, this study explored a set of simple and practical methods for evaluating the suitability of soil resources in arid mountainous area. The main evaluation basis is the slope of the soil, the thickness of soil layer, the content of gravel, the content of soil nutrients Content and other factors easy to get. The evaluation unit is a plot of land, which is divided by the status of land use plus the slope of the ground. Evaluation method using the “index of experience.” Use traditional methods or GIS mapping. This method is suitable for resettlement area and special planning area
