DYNAMIC MONITORING AND ANALYSIS OF GRASSLAND VEGETATION COVERAGE AND PRODUCTIVITY IN MULI REGION IN RECENT 20 YEARS
Taking the Muli region on the northern edge of the Qinghai Tibet Plateau as an example,through remote sensing monitoring and data inversion,the trend of vegetation coverage and productivity changes in Muli grassland over the past 20 years were obtained,and driving factors were analyzed.Conclusion:(1)In the past 20 years,the grassland vegetation coverage and NPP in the Muli region have shown fluctuating changes,but overall shown an increasing trend;(2)The hydrothermal conditions have a significant impact on the changes in grassland vegetation in the Muli region,and the impact of temperature on vegetation growth in the area is higher than that of precipitation.
