色林错流域—世界地理数据大百科辞条

色林错流域位于青藏高原腹地，地理范围是北纬30度03分22秒-北纬33度19分50秒，东经87度23分40秒-东经92度13分49秒，是青藏高原最大的内陆湖水系。色林错流域面积46,087.15平方千米，流域界线长2151.29千米，包括了西藏自治区申扎县大部分区域，安多县、班戈县部分区域以及谢通门县、南木林县和尼玛县的边缘区域。流域内有西藏最长的内流河—扎加藏布和西藏最大的湖泊—色林错。流域边界的划定是在ASTER GDEM(V2) 30m空间分辨率数据基础上，基于ArcGIS水文分析相关模块得到初步提取结果，最后在Google Earth遥感影像上修改生成。色林错流域数据包括线状数据和面状数据，采用.kmz和.shp格式存储。压缩后数据量为1.08MB。The Siling Co Basin is situated in the hinterland of the Qinghai-Tibet Plateau, with geographic bounds spanning 30°03′22″ N to 33°19′50″ N latitude and 87°23′40″ E to 92°13′49″ E longitude. It represents the largest endorheic lake system on the Qinghai-Tibet Plateau. The basin has a drainage area of 46,087.15 square kilometers, and the total length of its boundary measures 2,151.29 kilometers. Administratively, it covers most of Shenzha County, parts of Ando County and Baingoin County, as well as the marginal areas of Xaitongmoin County, Namling County and Nyima County, all within the Tibet Autonomous Region. The basin encompasses the longest endorheic river in Tibet, Zhajia Zangbu, and the largest lake in Tibet, Siling Co. The delineation of the basin boundary was first preliminarily extracted using relevant hydrological analysis modules in ArcGIS based on ASTER GDEM (V2) data with 30-meter spatial resolution, and then finalized through revisions on Google Earth remote sensing imagery. The Siling Co Basin dataset includes linear feature data and polygonal feature data, stored in .kmz and .shp formats. The compressed total size of the dataset is 1.08 MB.
