摘　　要：传统的土壤溶液溶解状况监测主要利用地面观测点分析土壤变化情况,存在不连续性且费时费力,不能满足大区域连续监测。基于此提出酸沉降污染造成的土壤溶液溶解状况遥感监测研究。确定土壤状况参数,反映土壤溶液溶解状况;对获取信息做大气纠正、降维运算及光谱匹配等处理;提取光谱数据,求取光谱平均值并储存,剔除异样光谱曲线,输出清晰遥感监测图像。The traditional monitoring of soil solution dissolution mainly uses ground observation points to analyze soil changes,which is discontinuous and time-consuming and laborious,which can not meet the continuous monitoring in large areas.Based on this,remote sensing monitoring of soil solution dissolution caused by acid deposition pollution is proposed.The parameters of soil condition are determined to reflect the dissolution of soil solution;the obtained information is processed by atmospheric correction,dimension reduction and spectral matching;the spectral data are extracted,the spectral average value is obtained and stored,the unusual spectral curve is eliminated,and the clear remote sensing monitoring image is output.
