Vegetation variation trend and its influencing factors in Urad Grassland over remote sensing

In this work, the temporal-spatial dynamic variation of vegetation coverage from 2010 to 2019 in Urad Grassland has been explored by remote sensing technique. The change precipitation and temperature obvious effects on vegetation, which affects agriculture stability ecosystem. Pixel dichotomy approach correlation analysis are introduced analyse temporal spatial evolution trend its response climate past 10 years. Specifically, between critical impacting factors such as fully investigated. results show study area was influenced effectors including climate, topography, human activities government policies. average annual showed a downward general 2019. Statistical indicates that is positive most parts area, while shows negative with difference various geographic features. As result, major natural factor affected dynamics grassland.
