  郭扎错是中国最高的咸水淡水湖。位于西藏自治区西北部日土县境内,地处昆仑山南麓的断裂带,有长距离的断层线崖,为构造湖。海拔5 080米,面积244平方千米,流域面积2 790平方千米。 郭扎错湖是我国海拔最高同时还拥有 咸水和淡水的混合湖,其北部为淡水,南部 为咸水,在同一个湖泊中有两种不同的水, 实属罕见。这是因为湖的北部有数十座6000米以上的冰川与雪山,水源相对充足,加之湖面海拔高,蒸发量相应减少,湖北半部的水有明显被冲淡的现象,故形成北半部湖水的矿化度低,所以湖北半部为淡水。相反,湖的南半部水源少,蒸发量大,矿化度高,故为咸水。 湖周是藏北羌塘高原极边远地区,也是待开发区和野生动物出没的地方。主要野生动物有被人们称为“高山之霸”的雪豹,大型 偶蹄动物、善于攀登险峻石崖的岩羊,珍稀国 家重点保护动物藏羚羊,体格大、生命力强的野牦牛,还有善于奔跑、成群结队、群居性强、并有观赏价值的藏野驴、盘羊、黄羊、熊以及 狼等。郭扎错地区可谓“世界最高天然动物 园”,可与非洲中部的“野生动物园”相媲 美了。Guo Zhacuo is the highest saltwater freshwater lake China. Is located in the territory of Rutog County in northwestern Tibet autonomous region is located inthe south of Kunlun Mountains, fracture belt, a long-distance fault line scarp,tectonic lake. At an altitude of 5080 meters, covering an area of 244 square km,the basin area of 2790 square kilometers. Guo Zhacuo lake is China's highest elevation also has mixed lake salt and fresh water, the north to the south tofreshwater, brackish water, there are two different kinds of water in the samelake, it is rare. This is because the north of the lake there are dozens of 6000meters above the glacier and snow capped mountains and the lake water, the relative abundance, high altitude, a corresponding reduction in evaporation,Hubei half of the water was diluted phenomenon, the formation of the northern half of the lake water mineralization degree is low, so the Hubei half for fresh water. On the contrary, the lake's southern half of less water, evaporation, high salinity, it is salty. Around the lake are very remote area of Qiangtang plateau,but also to the development zone and the wild animal haunts. The main wildanimal is known as the "mountain of the bully" snow leopard, large cloven hoofed animal, good at climbing steep rock cliffs of blue sheep, Tibetan antelope homekey protected animal rare country, large body, the vitality of wild yak, and is good at running, gathering in crowds and groups, gregarious, and has strongornamental value of the Tibetan wild ass, argali, Mongolian gazelle, bears andwolves. It may be said "Guo Zhacuo area the world's highest natural animal park",and Africa central "wild zoo" comparable.
