The research indicate that the aquatic ecosystem of Wuhan city lakes now is: elementary production and consumption keep high amount, and accumulate in the water bodies, then the benthon ,so much as fish's community to decline seriously, cause the main nutrients cycle and energy circulation in the system is obstructed, that means the "elementary production-elementary consumption-advanced consumption" replaced by the "elementary production-elementary consumption-analyze by itself – reproduction", this circulation of the the nutrients is unfavorable to the system.

生态系统结构研究表明武汉市湖泊水生生态系统目前所处状态：初级生产和初级消费维持较高生产量和现存量，在水体中积累，而较高层次的底栖生物乃致鱼类群落严重衰退，导致系统中主要物质和能量循环：初级生产—初级消费—高级消费受阻，代之而起的是初级生产、初级消费—自行分解—再生产的循环，不利于系统中物质转移。
