In the researching period, the total N/P of each monitoring point in east lake wereall greater than 16, this indicated the lake is short of phosphor, and are took P as thelimiting factor of plankton growth.
研究考察期内，阳澄东湖各监测点的总N／P都大于16，都以P为浮游生物生长的限制因子。
Chlorella pyrenoidosa, Daphnia magna and Xiphophorus helleri are the typical organisms of plankton, zooplankton and fish in aquatic ecosystem. The toxic effects of these three Pharmaceuticals on Chlorella pyrenoidosa, Daphnia magna and Xiphophorus helleri were studied in this research.
小球藻(Chlorella pyrenoidosa)、大型溞(Daphnia magna)和剑尾鱼(Xiphophorushelleri)分别是水生态系统中的浮游植物、浮游动物和鱼类三个营养级上的代表生物，本研究以小球藻、大型溞和剑尾鱼为试验生物，研究上述三种典型渔药对水生生物的毒性效应。
