摘　　要：为了研究青藏高原降水量时空差异对不同区域植被的影响,通过获取2016—2020年不同时间节点青藏高原降水数据与NDVI数据,采用定性与定量研究方法,分析不同降水量对不同区域植被的影响程度。结果表明,青藏高原降水时间分布呈由东南向西北方向递减的变化规律,甘肃南部、青海北部、新疆南部及西藏西部部分地区降水量与植被的相关性明显。In order to study the influence of temporal and spatial differences of precipitation on vegetation in different regions of Qinghai-Tibet Plateau,based on the precipitation and NDVI data of Qinghai-Tibet Plateau from 2016 to 2020,the influence degree of different precipitation on vegetation in different regions is analyzed by qualitative and quantitative research methods.The results show that the temporal distribution of precipitation over the Qinghai-Tibet Plateau decreases from southeast to northwest,there are obvious correlations in southern Gansu,northern Qinghai,southern Xinjiang and parts of western Tibet.
