海丁诺尔-全球变化数据大百科辞条

海丁诺尔，又名南海诺尔，是青藏高原上一个硫酸亚型咸水湖泊；位于东昆仑山南麓库赛湖东南侧，青海省玉树藏族自治州治多县境内。地理位置为35&deg29′52″ - 35&deg37′38″，93&deg3′44″ - 93&deg17′24″。海丁诺尔属于山间构造断陷湖泊，湖面高度4470 m，地势南北高、东西低，北邻昆仑山，南邻可可西里山。湖区位于高寒草原半干旱气候区，年平均气温-4 - -2℃，年平均降水量200 mm。湖区呈港湾状，多处湖湾通道狭窄，呈半封闭状泻湖，面积为81.96 km&sup2，湖岸线长269.40 km。湖区有79个形态各异的岛屿，其中有5个岛屿面积小于100 m&sup2，最大岛屿的面积为1.56 km&sup2，岸线长8.00 km；最小岛屿的面积为36.75 m&sup2，岸线长23.36 m。海丁诺尔水源主要依赖于季节性溪沟径流和地下潜水，海丁河是汇入该湖的主要河流。湖区植被主要有青藏苔草及紫花针茅等。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8.82 MB（压缩为2个文件，3.03 MB）。

Haidin Nor, also known as Nanhai Nor, is a sulfuric acid subtype saline lake on the Qinghai-Tibet Plateau. It is situated on the southeast side of Kusai Lake at the southern foot of the Eastern Kunlun Mountains, within Zhidoi County, Yushu Tibetan Autonomous Prefecture, Qinghai Province. Its geographic coordinates range from 35°29′52″N to 35°37′38″N, and 93°3′44″E to 93°17′24″E. Haidin Nor is an intermountain tectonic fault-depression lake with an elevation of 4470 m. The terrain is high in the north and south, and low in the east and west; it borders the Kunlun Mountains to the north and the Hoh Xil Mountains to the south. The lake area belongs to a semi-arid alpine steppe climate zone, with an annual average temperature of -4 to -2 ℃ and an annual average precipitation of 200 mm. The lake area is bay-shaped, with narrow channels in multiple lake bays, forming a semi-enclosed lagoon. It covers an area of 81.96 km² and has a shoreline length of 269.40 km. There are 79 islands of various shapes in the lake area, among which 5 islands have an area of less than 100 m². The largest island covers an area of 1.56 km² with a shoreline length of 8.00 km, while the smallest island has an area of 36.75 m² and a shoreline length of 23.36 m. The water source of Haidin Nor mainly relies on seasonal gully runoff and underground phreatic water, and the Haidin River is the main river flowing into the lake. The vegetation in the lake area mainly includes Carex moorcroftii and Stipa purpurea, etc. This dataset was developed based on Google Earth remote sensing satellite images (2015) and related maps. The dataset is stored in .kmz and .shp formats, consisting of 22 files with a total size of 8.82 MB (compressed into 2 files with a size of 3.03 MB).
