Inhibitory effects of macrophytes on the growth of algal community in Landscape water of Hefei city were evaluated. In the coexistence culture system of different macrophytes species (Ceratopteris siliquosa, Echinodorus opticus, Elodea densa, Limnophila aquatica, Myriophyllum aquaticum, Najas Guadalupesis, Nesaea crassicaulis and Rotala wallichiii) and nature algal community, only the macrophytes...
This paper proposed a hydrodynamic model for the Meiliang lake based on the Environmental Fluid Dynamical Code (EFDC). Considered the different speed of wind and the process of reservoirs operation, we have been analyzed the growth of microcystis aeruginosa. The results showed that: (1) when the wind speed is 3m/s, the velocity of water flow is more suitable for the growth of microcystis aeruginosa;...
The purpose of this work is to examine the effect of elevated carbon dioxide (CO2) and the relationship with wetland plant species in shallow lake wetlands in the East China. The wetland plant species such as Potamogeton crispun, Water hyacinth and Water iris were grown under two levels of CO2 in ambient and elevated (ambient CO2 + 200 μL L-1) respectively. They are grown in three replicated rooms,...
Nowadays, water pollution and eutrophication problem of rivers and lakes are widely and serious in China. Floating bed grown aquatic plants was applied to remove nutrient pollutants from the high-salinity river water. The experimental results showed that reed, Lythrum salicaria Linn and Alternanthera philoxeroides were the suitable species in this project. SD value in the river test section was significantly...
Growing switch-grass in a riparian buffer zone can be one of future best management practices in water resource protection. Switch-grass requires no fertilizers and less land and water. It was recently found to be a good source of biomass. In this study, Soil and Water Assessment Tool (SWAT) model was applied to a watershed to examine the effectiveness of buffer zones of switch-grass in reducing pollutants...
