摘　　要：文章以中国青藏高原地区为研究区,通过对1990-2019年气象站实测雪深数据(简称“实测雪深”)和卫星遥感反演雪深数据(简称“遥感雪深”)互补应用,分析实测雪深与遥感雪深的差值情况,评估遥感雪深的精度;通过多种方法对遥感雪深进行订正,形成质量最优的长时间序列遥感雪深订正数据集;总结积雪的时空变化典型趋势和特征,揭示在全球气候变暖过程中,雪深对时间变化的响应,以期为青藏高原雪灾防御工作中对积雪资料的应用提供参考。The article takes the Qinghai Tibet Plateau region of China as the research area,through complementary application of measured snow depth data from meteorological stations(hereinafter referred to as“measured snow depth”)and satellite remote sensing inversion snow depth data(hereinafter referred to as“remote sensing snow depth”)from 1990 to 2019,the difference between measured snow depth and remote sensing snow depth is analyzed to evaluate the accuracy of remote sensing snow depth.Using various methods to correct remote sensing snow depth,forming the best quality long-term series remote sensing snow depth correction dataset.Summarize the typical trends and characteristics of spatiotemporal changes in snow cover,revealing the response of snow depth to temporal changes in the process of global climate warming,in order to provide reference for the application of snow cover data in snow disaster prevention work on the Qinghai Tibet Plateau.
