| Abstract: | In this paper,the basic theories and methods of soil moisture monitoring by remote sensing are simply summarized,and then the national and international main progresses are reviewed.The results showed that the methods on soil moisture monitoring by remote sensing,which are mainly stood for by improved thermal inertia,CWSI and vegetation index,are becoming mature.The extensive application of GIS technology,the optimization of the model of remote sensing monitoring of soil moisture and the application of microwave are the key direct of future study.Meanwhile,some views are pointed out and indicated that the soil moisture monitoring should carry out a new way which combine many subjects in the future. |
