Water Quality Monitoring by Remote Sensing in Hushan Tailings Reservoir of Huji, Hubei Province

摘要

In this paper, the water quality of Hushan Tailings reservoir in Huji, Zhongxiang of Hubei province, was studied by remote sensing technology. Firstly, radioactive correction of ASTER data was processed by FLAASH Model, then the scatter was produced by SPSS, which was about reflectance or reflectance ratio of remote sensing(ASTER) andrnmeasured pollutant (Ag~+、Ba~(2+)、Hg~(2+)、Ca~(2+)、Mg~(2+)、F~-、Cl~-、NO~(3-)、H_2PO_4~-、SO_4~(2-), et.)at sampling sites. After experimentation,rnconversion model was built with significance test, F=68.797(F_(0.05)=11.821) , R=0.793.Finially, the data of water reflectance was processed with our model, and the distribution of corresponding pollutant was obtained.
