扎陵湖-世界地理数据大百科辞条

扎陵湖(Gyaring Lake)位于黄河谷地，青海省玛多县境内，是吞吐型淡水湖泊。扎陵湖又名查灵海，藏语称错加郎，因黄河携带大量泥沙入湖，风浪泛起时湖面呈灰白色，藏语意为“灰白色湖”，中更新世以前和鄂陵湖是一个完整湖泊，晚更新世完全分离成两个姊妹湖，历史上曾有“扎西鄂东”和“扎东鄂西”之争，1997年国务院正式确定两湖统一为“西扎东鄂”。扎陵湖地理位置为34&deg49′08″N-35&deg01′37″N，97&deg01′27″E-97&deg30′04″E。湖区呈不对称菱形状，周围群山环绕，南北两岸湖滩宽广，地势平缓，东岸陡峭。扎陵湖内有11个岛屿，湖区西北隅有3个岛屿自北向南一字排开，名“西三岛”，因有60多头白唇鹿栖息于此，故又名“鹿岛”。西三岛中，北岛是湖区中最大岛屿，面积为1.35 km&sup2、岸线长5.18 km；中岛的面积为0.86 km&sup2、岸线长4.28 km，南岛面积为0.41 km&sup2、岸线长2.60 km；扎陵湖集水区面积为542.33 km&sup2，湖岸线长232.20 km，湖面高程4 293 m。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6.69 MB（压缩为2个文件，2.29 MB）。

Gyaring Lake (alternatively named Chaling Sea; in Tibetan, it is called Cuojialang, literally meaning 'gray-white lake') is situated in the Yellow River valley within Maduo County, Qinghai Province, and is a freshwater lake with both inflow and outflow. The naming origin of Cuojialang lies in the fact that when the Yellow River carries large volumes of sediment into the lake and wind waves stir up the water, the lake surface takes on a gray-white hue. Prior to the Middle Pleistocene, Gyaring Lake formed a single contiguous lake with Ngoring Lake. The two lakes fully separated into sister lakes during the Late Pleistocene. Historically, there were debates regarding their naming convention, with two proposals: 'Zha Xi E Dong' and 'Zha Dong E Xi'. In 1997, the State Council of the People's Republic of China officially standardized their names as 'Xi Zha Dong E'. Geographically, Gyaring Lake spans latitudes 34°49′08″N to 35°01′37″N and longitudes 97°01′27″E to 97°30′04″E. The lake basin has an asymmetric rhombic morphology, surrounded by mountainous terrain on all sides. The lake beaches along the northern and southern shores are wide and gently sloped, while the eastern shore is steep. There are 11 islands within Gyaring Lake. Three islands located in the northwest corner of the lake are aligned linearly from north to south, collectively referred to as the 'West Three Islands'. Since over 60 white-lipped deer inhabit these islands, they are also known as the 'Deer Islands'. Among the West Three Islands, the northern island is the largest in the lake, with an area of 1.35 km² and a shoreline length of 5.18 km; the middle island covers an area of 0.86 km² with a shoreline length of 4.28 km; the southern island has an area of 0.41 km² and a shoreline length of 2.60 km. The catchment area of Gyaring Lake is 542.33 km², the total shoreline length is 232.20 km, and the lake surface elevation is 4293 m. This dataset was developed using Google Earth remote sensing satellite imagery from 2015 and relevant topographic maps. The dataset is stored in .kmz and shp formats, comprising 22 individual files with a total size of 6.69 MB (compressed into 2 files with a total size of 2.29 MB).
