Abstract

Abstract

The control of water bloom and the improvement of hydraulic conditions have become the key problems of ecological health restoration of urban lakes and rivers. The ecological water replenishment measures of Yongding River can alleviate the prone problem of water bloom in landscape slow-moving water bodies, including Lianshi No. 8 lake. However, the effect of the water replenishment process on water bloom control of landscape water bodies is not clear. Based on the data of water quality, hydrology and algae from 2019 to 2021, the two-dimensional coupling numerical model of hydrodynamic water quality of Lianshi Lake No.8 Lake was constructed to study the variation characteristics of chlorophyll-a content and slow flow area of Lianshi No. 8 Lake under different replenishment conditions. When the external water refill flow was within the range of 0.23 to 0.96 m³/s, the concentration of chlorophyll-a in the surface water of Lianshi Lake No.8 Lake was lower, and the slow flow area was small. This study can provide data support for the research of urban landscape water bloom control and formulation of water replenishment optimization schemes.
