Spatiotemporal Variation Trend of Vegetation Cover in Inner Mongolia Since 2010
Based on the NDVI data inversion of Inner Mongolia from 2010 to 2023,this study investigates the spatial distribution characteristics and variation trends of the annual maximum vegetation cover(FVC)in Inner Mongolia by combining ecological zoning data.The results show that from 2010 to 2023,the mean FVC in Inner Mongolia and each ecological zone has shown an increasing trend;in terms of spatial distribution,FVC generally decreases from the northeast to the southwest,with the overall mean FVC of forest areas＞grassland areas＞desert areas;the trend of FVC variation in Inner Mongolia is mainly increasing,with the proportion of area change trends of being not significantly increasing(53.07％)＞not significantly decreasing(25.52％)＞extremely significantly increasing(7.83％)＞significantly increasing(7.12％)＞no change(4.94％)＞significantly decreasing(1.01％)＞extremely significantly decreasing(0.52％);the areas of extremely significant increase coincide spatially with the Horqin Sandy Land,the Mu Us Sandy Land,and the Kubuqi Desert,indicating that certain achievements have been made in the recent management of sandy lands and deserts in Inner Mongolia.
