摘要
综述了沉水植物在水生态系统中的环境价值和渔业价值,生物环境与非生物环境因子对沉水植物的影响,以及受损水域中重建沉水植被的研究进展。
Submerged vegetation is looked as forest submerged in water. It is very important for the structure and function of the aquatic ecosystem. At the same time, environment factors affect the living of submerged vegetation greatly. Submerged vegetation's functions are as follows: It supports the diversities of livings in water, influences the evolution of the water ecosystem, purifies the quality of water, supplies some food for hydrobiology directly and releases oxygen into water by photosynthesis. On the other hand, environmental factors (water temperature, light, nutrition, periphytic algae, aquaculture, harvest, and so on) have impacts on submerged macrophytes evidently. Up to now, some studies on the restoration of submerged macrophytes in eutrophic waters have been made and this will accelerate the development of ecologic restoration of aquatic ecosystem.
