Overview of Grassland Degradation Research Based on Remote Sensing Monitoring

In recent years, grassland degradation has become one of the most important ecological problems in China under interwoven influence environmental and human factors. Based on analysis spatial-temporal characteristics driving factors order to deeply understand research status monitoring methods evaluation index system, this paper mainly investigates progress remote sensing indicators. Furthermore, summarizes more commonly used methods, analyzes existing indicators degradation, points out direction future. Finally, a comprehensive system are established paper. Research findings: because variety types emergence establishing classify summarize different can lay foundation for development future provide ideas. It is trend
