利用蓝藻漂移三维数学模型研究太湖蓝藻防控工程
Study on cyanobacteria prevention and control projects in Taihu Lake based on a three-dimensional mathematical model of cyanobacteria drif
摘要
Abstract
Meiliang Lake is a severely affected region for cyanobacteria blooms and a key area for cyanobacteria control.To address the issue of cyanobacteria accumulation in Meiliang Lake,Wuxi City implemented the offshore cyanobacteria prevention and control project in Meiliang Lake.Using a three-dimensional mathematical model of cyanobacteria drift in Taihu Lake as the main tool,this study investigated the impacts of the completed Meiliang Lake cyanobacteria prevention and control project on hydrodynamics in Meiliang Lake,cyanobacteria blooms,and water sources in Taihu Lake.The results showed that under different wind field conditions,the flow field structure within Meiliang Lake changed considerably after the completion of the cyanobacteria prevention and control project,while the overall flow velocity magnitude showed no significant variation.The hydrodynamic intensity increased in the northern part of the bay,decreased in the central part,and showed no obvious change at the bay mouth.The Meiliang Lake cyanobacteria prevention and control project can effectively intercept cyanobacteria entering the Meiliang Lake mouth,reducing the risk of cyanobacteria blooms along the northern coast of Meiliang Lake and at the Liangxi River estuary.Under different wind field conditions,no significant changes in cyanobacteria distribution were observed at water sources in Taihu Lake before and after the completion of the project.This study provides a theoretical reference and scientific guidance for the control of cyanobacteria blooms in Taihu Lake in the future.关键词
