接坝山地土壤水蚀、风蚀预报模型及强度分级研究——以丰宁满族自治县小坝子乡为例

Study on Prediction Model and Intensity Classification of Soil Erosion in Jieba Mountain ——A Case Study of Xiaobazi Country

以丰宁满族自治县小坝子乡为研究对象 ,在全面调查 ,获取资料 ,建立土地利用现状属性数据库的基础上 ,运用通用土壤流失方程 U SL E和打分评价相对模型分别建立了小坝子乡土壤水蚀、风蚀预报模型 ;并通过建立分级指标体系 ,对小坝子乡土壤侵蚀强度进行了分级研究。旨在探求接坝山地土壤侵蚀的特点和侵蚀程度 。

Takes Xiaobazi country,which locates in Fengning Manchu autonomous county,Hebei Province,as a study project,through comprehensive investigation,we set up the database by means of RS,GIS.Then,according to USLE,and location conditions,the prediction model of the soil's water erosion in Xiaobazi was discussed and established.At the same time,the prediction model of wind erosion of soil was set up,by the way of relative appraisal.Lastly,with the standard and index of soil erosion,the intensity classification of both water erosion and wind erosion were carried out.The goal is to analyze and conclude the characteristics of soil erosion in Jieba mountain,and to provide some scientific foundation for regional eco-environment conservation.
