鄱阳湖富营养化的生物学评价

BIOLOGICAL EVALUATION ON EUTROPHICATION OF POYANG LAKE

利用浮游藻类种群组成和数量的变化，以及水体中叶绿素ａ含量和初级生产力等生物学指标对湖泊的营养状况进行评价，具有直观、准确和易操作等优点。本文以上述生物学指标对鄱阳湖水体营养状况进行了分析比较。

Using floating algae and their chlorophyll a content and primary productivity as the biological indexes to evaluate the lake's nutrition status has some advantages in accuracy,more direction in sense and easy operation.On the basis of analyzing and comparing of the nutrtion status of Poyand Lake by using of this indexes,we concluded that the nutrition level of Poyang Lake is in primary stage of the poor-middle nutrition status.
