| Abstract: | The lowering of wetland water table and groundwater table gives rise to soil salinization,and at the same time,soil salinization has serious impacts on the wetland survival and development.With the Yeyahu wetland as a study case,using the remote sensing images,making in-depth analysis of the spectral characteristics of the salinized soil,and then extracting special information of soil salinization in virtue of the PCI and ENVI image processing platform,this paper has summarized the dynamic trend of soil salinization in the wetland area. |
