可鲁克湖—全球变化数据大百科辞条

可鲁克湖，蒙语意为“多草的芨芨滩”，位于托素湖北侧，柴达木盆地东北缘宗务隆山南麓、巴音河尾湖。位于青海省海西蒙古族藏族自治州德令哈市境内。地理位置为37&deg14′28″N - 37&deg19′55″N，96&deg50′36″E - 96&deg57′14″E，湖面海拔高度2817 m，可鲁克湖面积为56.67 km&sup2，湖岸线长65.05 km。可鲁克湖是微咸淡水湖，湖区由9个沙岛组成，其中最大沙岛的面积为0.01 km&sup2，岸线长502.34 m，最小沙岛的面积为82.71 m&sup2，岸线长37.96 m。湖区位于荒漠、半荒漠干旱气候区，年平均气温3.7℃左右，年日照时数长约3182 h，年降水量190 mm左右，年蒸发量2400 mm左右。水源主要依赖于地表径流和冰川融雪补给，巴音河和巴罗根河两条河流直接汇入湖区；巴音河源于野牛脊山和哈尔科山，是注入湖区最大的地表径流。源于宗务隆山的埃斯肯北麓的巴罗根河位居其次。该数据集是在Google Earth遥感卫星影像（2015年）及相关的地图基础上研发完成。数据集以.kmz和.shp格式存储，由22个文件组成，数据量为2.44 MB（压缩为2个文件，864 KB）。

Keluke Lake, which means "dense grassy Achnatherum splendens beach" in Mongolian, is located on the northern side of Tosu Lake, at the southern foot of Zongwulong Mountain on the northeastern margin of the Qaidam Basin, and at the tail of the Bayin River. It is situated within Delingha City, Haixi Mongolian and Tibetan Autonomous Prefecture, Qinghai Province, China. Its geographical coordinates range from 37°14′28″N to 37°19′55″N and 96°50′36″E to 96°57′14″E, with a lake surface elevation of 2817 m, a total lake area of 56.67 km², and a shoreline length of 65.05 km. Keluke Lake is a slightly brackish freshwater lake. The lake basin consists of 9 sand islands: the largest sand island covers an area of 0.01 km² with a shoreline length of 502.34 m, while the smallest sand island has an area of 82.71 m² and a shoreline length of 37.96 m. The lake area is located in an arid desert and semi-desert climate zone, with an annual average temperature of approximately 3.7℃, annual sunshine duration of about 3182 h, annual precipitation of around 190 mm, and annual evaporation of approximately 2400 mm. Its water sources mainly rely on surface runoff and glacial snowmelt recharge; two rivers, the Bayin River and the Barogen River, directly discharge into the lake area. The Bayin River originates from the Yeniujishan and Harke Mountains, and is the largest surface runoff feeding the lake area, while the Barogen River, which originates from the northern foot of the Aisiken in the Zongwulong Mountains, ranks second. This dataset was developed based on Google Earth remote sensing satellite imagery (2015) and relevant maps. It is stored in .kmz and .shp formats, consisting of 22 files with a total data volume of 2.44 MB (compressed into 2 files, 864 KB).
