Summary: | The algae, as the primary producer of the water ecosystem, are the basic part of food chain in aquatic ecosystem. The flow pattern and hydrological process of the river have been significantly changed by the construction of the high dams. Not only the natural hydrological characteristics and physical and chemical conditions of the river were changed by the obstacle of the dams, but also the habitat environment on which the phytoplankton live, and its community structure, biomass and primary productivity of the water further were affected. In this paper, the research on the effect of river hydrological regime change on the primary productivity of water body were summarized and summarized. In the future, further research can be carried out in these aspects: (i) the analysis of the key factors affecting the primary productivity; (ii) clarifying the mechanism of the influence of hydrological situation change on the primary productivity and its distribution of algae in the reservoir area and downstream channel; (iii) establishing the coupling relationship between the change of hydrological regime and the primary productivity of phytoplankton. |
