遥感技术在土壤侵蚀调查中的应用——以北京市密云水库北部地区为例

Remote Sensing Application In Soil Erosion Survey—Take The Northern Area of Miyun Reservoir As An Example

以密云水库北部地区为例 ,对遥感技术在土壤侵蚀调查中的应用进行了阐述。在调查中 ,首先利用遥感图像进行判读并进行实地验证。然后 ,根据影响土壤侵蚀的生态环境因子 ,建立了数学评判模型 ,对该区的土壤侵蚀情况进行了评判。这为该区的水土保持规划。

Taking the Northern area of Miyun reservoir as an example,this paper discuss the remote sensing application in soil erosion survey.Firstly,Satellite images have been integrated and the ground real conditions have been rectified,Secondly,according to ecological environmental factors that can affect soil erosion,the mathematics Model of judrement have been built,and the soil erosion have been judged,the result of the research can serve the plan,management and decision in the soil erosion prevention.
