洱海弥苴河河口湿地流场模拟及治理措施

Flow field simulation and control measures of Erhai lake Miju river mouth wetland

洱海弥苴河河口湿地整治是洱海保护治理与流域生态建设的一项重要内容。通过数值模型方法进行模拟可对湿地现状及相应措施实施后的改善效果进行直观分析。利用二维水动力模型模拟湿地现状,提出主要存在问题和相应治理措施,并进行模型验证。验证结果表明,所选工程措施可有效治理洱海弥苴河河口湿地长期存在进水不畅等问题,有效提高河口区域生态环境水平。

The renovation of Miju river mouth wetland is an important part of Erhai lake protection and ecological construction.By using numerical model,the current situation of wetland and the improvement effect after corresponding measures could be analyzed.The current situation of Miju river mouth wetland is simulated by the MIKE 21(two-dimensional hydrodynamic model).Based on the simulation result,the corresponding measures were aimed at the main problem in current situation.According to the measures,the model will be verified.The verification results showed that the selected engineering measures can solve the problem of water inflow and improve the ecological environment in this area.
