岱海水质咸化过程中营养状况的变化
PRELIMINARY STUDY ON THE CHANGES OF TROPHIC STATE DURING THE PROCESS OF WATER SALINIZATION IN DAIHAI LAKE,CHINA

摘要: 通过1996年夏季对岱海的综合考察,采用营养状态指数(TSI)法对岱海进行了水质营养状况的综合评价和比较分析,并结合自往年关于岱海的理化因子和营养元素含量资料,对岱海水质咸化过程中水体营养状况的变化进行了比较分析。在此基础上,还初步探讨了岱海水质咸化过程与营养状况变化之间的关系。Abstract: Daihai Lake is a semi-saline-alkaline lake,which located in Inner Mongolia plateau of China,its geographical position being 112°33′31″—40″E,40°29′7″—37′6″N.Based on the results of the chemical and biological surveys of Daihai Lake in summer 1996,this study dealt with a trophic state assessment of water quality in 1996 and comparative analysis on the changes of trophic state during the process of water salinization.Chloride ion,pH and total alkalinity of the lake were gradually increased during the study period,which approach to the upper limit of freshwater fish survival.According to above significant changes, the conclusion could be drawn that the process of salinization of Daihai Lake is getting strong.Also,in the study,the concentration changes of calcium and magnesium ion,ratio of calcium and magnesium,and total hardness is regarded.
