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