柯柯盐湖—全球变化数据大百科辞条

柯柯盐湖地处青藏高原柴达木盆地东北隅，青海省境内，又名达乌苏诺尔，意为“青色的盐湖”，是我国重要的食盐产地之一。地理位置 36&deg52′35″N—36&deg59′24″N，98&deg3′17″E—98&deg21′15″E。湖区形状不规则，呈近似长方形态，湖水面积为119.73 km&sup2，湖岸线长77.70 km。湖区位于干旱气候区，年平均气温为2~4℃，年降水量约150 mm，年蒸发量约3000 mm，水源补给主要依赖于地下潜水和地表时令径流。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15个文件组成，数据量为178 KB（压缩为2个文件，77.1 KB）。

Keke Salt Lake is located in the northeastern Qaidam Basin of the Qinghai-Tibet Plateau, within the territory of Qinghai Province. It is also known as Dabsan Nur (Dawusu Nuor), which means "green salt lake", and is one of the important salt production areas in China. Its geographical coordinates range from 36°52′35″N to 36°59′24″N, and from 98°3′17″E to 98°21′15″E. The lake has an irregular shape, approximating a rectangle, with a water area of 119.73 km² and a shoreline length of 77.70 km. The lake region is situated in an arid climate zone, with an annual average temperature of 2–4°C, annual precipitation of approximately 150 mm, and annual evaporation of about 3000 mm. Its water recharge mainly relies on underground phreatic water and seasonal surface runoff. This dataset was developed based on Google Earth remote sensing satellite images (2015) and relevant maps. The dataset is stored in .kmz and .shp formats, consisting of 15 files with a total size of 178 KB (compressed into 2 files, 77.1 KB).
