摘　　要：为了使团泊洼湖泊环境得到良好地改善,湖泊资源得到有效地利用和保护,运用综合营养状态指数法(TLI)对团泊洼富营养化程度进行分析评价,并借助硅藻指标及其在湖泊中的组合变化,分析其对湖泊营养变化过程的指示意义。结果表明:团泊洼处于富营养状态,湖泊中有梅尼小环藻(Cyclotella me-neghiniana)、极微小环藻(C.atomus)组合出现,表明湖泊水体已经开始向富营养化方向转变。C.dis-tinguenda是团泊洼特有的优势属种,该属种喜高盐度湖泊环境,一定程度上反映出团泊洼的盐渍化问题,同时该属种的存在表明,团泊洼为高盐度咸水湖泊,与团泊洼有较高的电导率和矿化度监测数据是相一致的。In order to make Tuanpowa environment improved,lake resources get effective utilization and protection,the author mainly used comprehensive nutrition state index method（TLI） to analyze and evaluate the Tuanpowa eutrophication degree.and made use of the combination of diatoms to instruct the lake nutrient process.The result indicated that Tuanpowa was in eutrophic state.Cyclotella meneghiniana and C.atomus appeared in Tuanpowa,it suggested that the lake had started to shift to eutrophication.C.distinguenda was the unique advantage specie for Tuanpowa,it was fond of high salinity environment,which was in accord with the high conductivity and degree of mineralization of Tuanpowa.
