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2542.30×10^(3) km^(2)。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。
The Tibetan Plateau(TP)is an unique geomorphic region composed of specific geomorphic types,such as extreme high mountains,hills,plains,and plateaus of high altitude or sub-high altitude.There are different opinions as to the exact scope of the TP.According to the latest results of long-term fieldwork,questions related to the area and boundaries of the TP were reviewed geographically.The geomorphologic features were used to define the boundary.A 1׃1,000,000 geomorphologic map was compiled based on a 1׃100,000 aerial photographic map,a 1׃500,000 topographic map,and the interpretation of satellite images.The boundary of the TP was delineated by referring to a relief map in 1׃3,000,000 scale.The position of the boundary was quantitatively determined with GIS,and an electronic version of the map of the TP was compiled.The main conclusion is that:the TP starts from the southern edge of the Himalayan Range(not including the low Himalayas Mountains);abuts India,Nepal and Bhutan;connects to the northern edge of Kunlun,Altun and Qilian Mountains;and joins the Tarim Basin and Hexi Corridor in Central Asia.To the west of the TP are the Pamir and Karakorum Mountains,bordering on Kyrgyzstan,Tajikistan,Afghanistan,Pakistan,and Kashmir.To the east of it are the Yulong Jokul,Daxueshan,Jiajin,and Qionglai Mountains as well as the south or east piedmont of the Mt.Minshan.The TP joins the Qinling Mountains and the Loess Plateau in its eastern and northeastern part.It ranges from 25°59′37″N to 39°49′33″N,and from 73°29′56″E to 104°40′20″E,covering an area of 2542.30×10^(3) km^(2),with a total boundary length of about 11,745.96 km.
