【摘要】 抚仙湖共有藻类植物７门，５３属，６６种，个体数量平均为８７２３６个／Ｌ．群落结构以绿藻、硅藻和蓝藻为主，三门的种类数占全湖总数的７６％，个体数为总量的９０％．在对藻类种类、数量、叶绿素、初级生产力、生物量等进一步进行全面调查的基础上，从藻类区系和种群数量方面对湖泊的营养化程度进行了评价和预测，提出了防止富营养化的措施，对如何保护利用藻类资源提出了建议更多还原

【Abstract】 Involved 7 phyllum, 53 genera and 66 species of algae were found in Fu-xian lake, the average density was 87 236 units per litre, dominated groups mainly were green algae, diaton, blue-green algae, which accounted of 76% of the total species number, and amounted to 90% of the total mumbes of algae individulasin this lake. On the basis of further myers tigation about the algae species, population,chlorophyll content, Primary productivity and biomass, Ertuophication degree of the lake was evaluated and anticipated from the aspects of algae flora and population. Suggestion were given on how to protect and utylize the algae resources, and the meacures of preventing eutrophication.更多还原
