摘要
应用遥感技术,对密云水库北部地区的土壤侵蚀情况进行了调查与评价。在研究中,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,建立数学评判模型,并对土壤侵蚀情况进行评判。
By the remote sensing,this paper surveys and discusses the soil erosion in the northern area of Miyun reservoir. First, Satellite images is integrated and the ground real conditions are rectified. Second, according to ecological environmental factors that can affect soil erosion, the mathematics model of judgment is built, and the soil erosion is judged.
