内蒙古达里诺尔湖水质现状调查

Investigation of Water Quality in the Dalinor Lake in Inner Mongolia

通过应用各种物理及化学仪器分析了达里诺尔湖水温、酸碱度、溶解氧、各种离子、总含盐量等因子,根据以往水质调查结果及这次测定数据比较,达里诺尔湖的pH有不断上升的趋势,这将危及到雅罗鱼及水中生物的生存,而其他各种离子均有小幅度的上升,溶解氧基本能满足鱼类的生存需求。通过水质的调查结果分析,使瓦氏雅罗鱼及其他水生生物更好地发挥在达里诺尔湖中生存的潜力。

Dalinor Lake is the second largest inland lake in Inner Mongolia. A few species of fish including cruclan carp（ Carassius carassius）and Amur ide（ Leuciscus waleckii）are found in the lake due to physical, chemical environment, especially high alkalinity. The water quality including water temperature, alkalinity, dissolved oxygen, and various ions was determined in the lake. It was found that the pH increased, threatening the various aquatic organisms including Amur ide to survive. The other ions had a slight increase, but the dissolved oxygen level met the basic needs for survival of fish.
