青藏高原土地利用数据（1992、2005和2015）（V1.0）

基于2015年欧空局ESA GlobCover全球陆地覆盖数据，结合中科院地理资源所土地利用数据NLCD-China、清华大学全球土地覆被FROM-GLC数据、美国NASA的MODIS全球土地覆被MCD12Q1数据、马里兰大学全球土地覆被UMD、美国USGS土地覆被数据IGBP DISCover，构建了青藏高原LUC分类系统以及其余数据分类系统的转换规则，构建土地覆被分类置信度函数和地类融合规则，进行土地覆被产品融合与修正，完成了青藏高原土地利用数据V1.0（1992,2005，2015，,300m×300m栅格，一级分类）

Based on the 2015 European Space Agency (ESA) GlobCover global land cover data, combined with land use data NLCD-China from the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences, global land cover data FROM-GLC from Tsinghua University, MODIS global land cover product MCD12Q1 from NASA of the United States, global land cover product UMD from the University of Maryland, and land cover data IGBP DISCover from USGS of the United States, we established the Land Use/Cover (LUC) classification system for the Qinghai-Tibet Plateau and the classification conversion rules for the remaining datasets. We also developed land cover classification confidence functions and land category fusion rules to perform land cover product fusion and correction, and finally completed the Qinghai-Tibet Plateau Land Use Data V1.0, which covers the years 1992, 2005 and 2015, with a spatial resolution of 300m×300m grid and adopts first-level classification.
