青藏高原逐年500米分辨率植被图（2000-2022）

本数据集为青藏高原2000-2022逐年500米分辨率植被图。该数据集基于Google Earth Engine (GEE) 平台和长时序逐年植被制图方法，通过地形、气象和MOD09A1遥感数据生成。基于2189条验证样本表明，本数据集的总体精度达83.27%，其中作为参考年份的2020年植被图精度达83.32%，Kappa系数为0.82。该数据集有助于阐明全球变暖背景下青藏高原植被的时空演变特征。

This dataset is a yearly 500-meter resolution vegetation map of the Qinghai-Tibet Plateau spanning from 2000 to 2022. It is developed based on the Google Earth Engine (GEE) platform and long-time-series annual vegetation mapping methods, using topographic, meteorological and MOD09A1 remote sensing data. Based on 2189 validation samples, the overall accuracy of this dataset reaches 83.27%. Specifically, the vegetation map for the reference year 2020 achieves an accuracy of 83.32% with a Kappa coefficient of 0.82. This dataset helps clarify the spatiotemporal evolution characteristics of vegetation on the Qinghai-Tibet Plateau under the background of global warming.
