摘要
巴里坤湖在非冰冻期全湖水温平均为１４．５℃．ＰＨ值弱酸性，全湖平均为６．７８，波美度平均为１８．５°Ｂｅ’．变动在７～２４°Ｂｅ之间；硬度高，平均为５３６．７ｍｅ／Ｌ．碱度与一般盐湖相比较为小，平均为１４．８５ｍｅ／Ｌ；溶解氧含量平均为２．８８１ｍｇ／Ｌ．耗氧量较高．平均含量为３１．５ｍｇ／Ｌ．全湖平均水深为２４．６ｃｍ波动在５～７０ｃｍ之间．阴离子主要以ＳＯ２、Ｃｌ－为主．二者全湖平均含量达７２．９３ｇ／Ｌ．阳离子以Ｋ＋、Ｎａ＋为主．平均含量为５２６９．５ｍｅ／Ｌ．其次是Ｍｇ２＋，平均含量为４８１．７ｍｅ／Ｌ，主要营养盐含量较低．各项理化因于均存在明显的季节差异和水平分布差异．该湖独特的理化特点只为广盐性和耐高盐，耐低氧水生生物提供了生存条件．是卤虫生存比较理想的水域．卤虫业有很大的潜力．
The average water temperature of Barcol salt lake is 14. 5 ℃during non glaciation periods, pH value is 6. 78, slightly sour. The mean duro is 536. 7 me/L, The average alkalinity is 1 4. 85 me/L, Less than content of general salt lake. The mean dissolved oxygen is 2. 88 mg/L. The chemical oxygen demand is high in this Lake, its average content is31. 5 mg/L. The mean water depth is 24. 6 cm (5～70). The main-ions of this lake are SO and Cl-, their average content are 72. 93 g/L, The dominant catopms are K+and Na+, their average content 5 269. 5 me/L. The average content of main nutrient salt is low in this lake. There are seassonal and horizonal difference in chemical -physical fators. The special water enviroment provides probability for A. barkolica survival
