岱海生物群落结构的演变及其对渔业发展的影响

Evolution of Biological Community and Fisheries Development in Daihai Lake, Inner Mongolia

岱海水生生物种类贫乏 ,生物量低 ,渔产力不高 .优化岱海水体生物群落组成 ,引种耐低温、耐盐碱的水生植物和藻类 。

The fish productivity of Daihai Lake is low due to the poor species richness and low biomass of aquatic communities. The biomass and structure of biological structure, evolution as well as the impacts on the fishery development are analysed. For the sustainable development of fisheries in Daihai Lake, some suggestions are put forward. i. e., introducing low temperature proof, salinity proof aquatic plants and algae, regulating fish community structure improving environment quality for habitation, and so on.
