云龙水库流域—全球变化数据大百科辞条

云龙水库是昆明掌鸠河引水供水工程的水源工程，于2007年正式建成蓄水，水库位于金沙江水系二级支流掌鸠河上游峡谷河段内。云龙水库流域是云龙水库的汇水区，位于云南省昆明市禄劝彝族苗族自治县和楚雄彝族自治州武定县境内。其地理位置为：25°43′34″N - 26°07′49″N，102°16′06″E - 102°35′13″E。云龙水库流域总面积为746 .09 km²，流域界线长165.74 km，最高海拔3155 m，最低海拔2026 m。流域内主要为岩溶-构造成因的峡谷地貌，是山地构造侵蚀形成的河谷，景观破碎。云龙水库的供水量占昆明市供水总量的70%，保障了昆明市及周边地区的饮用水供应。该数据集是在ASTER GDEM遥感卫星影像及Google Earth等相关的地图基础上研发完成。数据集以.kmz和.shp格式存储，由14个数据文件组成，数据量为434 KB（压缩为2个文件，181 KB）。

Yunlong Reservoir is the water source project of the Zhangjiuhe River Diversion and Water Supply Project in Kunming. It was officially completed and impounded in 2007, and is located in the upstream canyon section of Zhangjiuhe River, a second-order tributary of the Jinsha River system. The Yunlong Reservoir Basin, the catchment area of Yunlong Reservoir, is situated in Luquan Yi and Miao Autonomous County of Kunming and Wuding County of Chuxiong Yi Autonomous Prefecture, Yunnan Province. Its geographical coordinates range from 25°43′34″N to 26°07′49″N and from 102°16′06″E to 102°35′13″E. The total area of Yunlong Reservoir Basin is 746.09 km², the length of the basin boundary is 165.74 km, the maximum elevation reaches 3155 m, and the minimum elevation is 2026 m. The basin is mainly dominated by karst-tectonically formed canyon landforms, which are valleys shaped by mountain tectonic erosion with highly fragmented landscapes. The water supply from Yunlong Reservoir accounts for 70% of Kunming's total water supply, ensuring the drinking water supply for Kunming and its surrounding areas. This dataset was developed based on ASTER GDEM remote sensing satellite images and relevant maps such as Google Earth. The dataset is stored in .kmz and .shp formats, comprising 14 individual data files with an uncompressed total size of 434 KB (compressed into 2 files with a size of 181 KB).
