遥感测绘技术在土壤有机污染监测中的应用研究

Application of Remote Sensing Mapping Technology in Monitoring Soil Organic Pollution

针对传统土壤有机污染监测技术存在污染监测性能较差的问题,基于遥感测绘技术设计一种新的土壤有机污染监测方法。首先基于遥感测绘技术获取土壤的遥感数据,并对其实施预处理,包括几何校正和辐射校正。然后对土壤有机污染物实施光谱特征分析,获取土壤有机污染物对土壤光谱的影响,通过单变量回归方法构建回归模型,以实现土壤有机污染监测。为了证明该监测方法的监测性能较好,将传统监测方法与该方法进行对比实验,实验结果证明该监测方法的污染监测性能更优。

In view of the poor performance of traditional soil organic pollution monitoring technology,a new soil organic pollution monitoring method based on remote sensing mapping technology is designed.Firstly,the remote sensing data of soil is obtained based on remote sensing mapping technology,and the soil is pretreated,including geometric correction and radiation correction.Then,the spectral characteristics of soil organic pollutants were analyzed to obtain the influence of soil organic pollutants on the soil spectrum,and the regression model was constructed by univariate regression method to realize the monitoring of soil organic pollution.In order to prove that the monitoring performance of this monitoring method is better,a comparative experiment is conducted between the traditional monitoring method and this method,and the experimental results show that the pollution monitoring performance of this monitoring method is better.
