Analysis of Satellite Remote Sensing Technology in the Evaluation of Agricultural Non-point Source Pollution

Abstract

Non-point source pollution is an important source of water pollution,thus constituting one of the decisive factors affecting water environment.The commonly used agricultural non-point source pollution evaluation methods include statistical models and physical models of the computer.No matter what kind of modeling the researchers adopt,a variety of data acquisition types and the evaluation of the accuracy of the verification results make up the main bottleneck.In order to make people aware of the importance of satellite remote sensing technology in agricultural non-point source pollution evaluation,this paper made an application analysis of the access capability and feasibility of the satellite remote sensing technology from the angle of data types required by the study of the non-point source pollution,and also forecast the application potential of the satellite remote sensing technology in the precision verification of the agricultural non-point source pollution evaluation results.
