摘要: 长期以来,种种因素导致学者们对青藏高原确切范围的认识与理解存在差异。作者 (2002) 根据相关领域研究的新成果和多年野外实践,论证确定青藏高原范围和界线的原则,结合信息技术方法对青藏高原范围与界线位置进行了精确的定位和定量分析,得出:青藏高原在中国境内部分西起帕米尔高原,东至横断山脉,南自喜马拉雅山脉南缘,北迄昆仑山—祁连山北侧。结合新的矢量数据分析,青藏高原范围为25°59′37″N~39°49′33″N,73°29′56″E~104°40′20″E,边界总长度为11745.96 km,面积为2542.30×103 km2。鉴于2002年的条件,《论青藏高原范围与面积》一文的矢量数据没有渠道与论文同步发表,现借中科院地理资源所启动的科学数据出版平台,将更新后的数据公开出版,以便大家获取、引用和应用此数据。

Abstract: The dataset of regional vegetation changes from 1981-2006 in the Qinghai-Tibet Plateau was developed based on the NOAA AVHRR NDVI from 1981-2006. Seven vegetation change clusters and four vegetation change sub-regions are included in the dataset. The seven vegetation change clusters include the significantly decreased cluster, the decreased cluster, the slightly decreased cluster, the no change cluster, the slightly increased cluster, the increased cluster and the significantly increased cluster. The four vegetation change sub-regions include the western vegetation change increasing sub-region; the western vegetation stable sub-region; the middle vegetation change increasing sub-region; and the eastern vegetation degreasing sub-region.
