| 摘 要： | 根据我国２４个有代表性湖泊的１９８７－１９８８年调查资料，选择Ｃｈｌａ，Ｔｎ，ＴＰ，ＣＯＤＭｎ，ＳＤ作为评价参数，采用综合评分指数法，对湖泊富营养化程度进行了初步评价。结果表明，所调查的２４个湖泊中，富营养湖泊１６个，占调查总数的６６．６％；中富营养湖泊４个，占１６．７％；中营养湖泊４个，占１６．７％；贫营养湖泊为零。与国外湖泊相比较，主要评价参数Ｃｈｌａ，ＴＮ，ＴＰ的数值普遍较高，富营养湖泊的比

| Abstract: | On the basis of analysis data about twenty-four representative lakes in China which were investigated in 1987-1988, this paper selects Chla, TP, TN, COD and SD as assessment indexes, and uses comprehensively trophic level index method to assess trophic level of main lakes in China. Results show that among these twenty-four lakes, sixteen lakes (66.6%) are eutrophic, four lakes (16.7%) are mesotrophic-eutrophic, four lakes (16.7%) are mesotrophic and none of oligotrophication. Comparing with foreign lakes, values of main assessment indexes--Chla, TP, TN arecommonly high, percentage of eutrophic lakes among total investigated lakes is great and the harm caused by eutrophication is serious. Especially, the problem in eutrophic lakes which are used as drinking water source is now worrying people universally. In view of this situation of serious eutrophication of lakes in China, measures of prevention and improvement should be performed immediately. |
