洪泽湖滞洪区工程建设地表水环境影响评价
|
摘要
洪泽湖滞洪区建设工程对确保洪泽湖大堤安全、减轻洪泽湖防洪压力、减少洪水灾害及保护下游城市的安全起着十分重要的作用,工程建设势必对洪泽湖滞洪区的水环境产生一定的影响。通过洪泽湖滞洪区工程建设的施工期及运行期的水环境数学模型的模拟与评价,预测得出工程建设的施工期将会使局部地区地表水的SS提高,滞洪期洪水中的COD、氨氮和总磷都不达标。通过进一步评价得出,随着工程的完建运行和生态环境保护措施的实施,地表水环境将会重新恢复,使得水质达标,对于洪泽湖水环境管理和水利工程影响后评价具有一定的指导意义。
The construction of flood detention basin in Hongze Lake plays important role in ensuring the safety of Hongze Lake embankment,reducing flood control pressure in Hongze Lake,reducing flood disasters and protecting the safety of downstream cities. The project construction will inevitably affect the water environment of Hongze Lake flood detention area. Through the simulation and evaluation of the mathematical model of the water environment during the construction period and operation period of Hongze Lake flood detention area construction project,it is predicted that the construction period of the project will increase the SS of surface water in some areas and the COD,ammonia nitrogen and total phosphorus cannot meet the national standard.Through further evaluation,it is concluded that with the completion of the project and the implementation of ecological and environmental protection measures,the surface water environment will be resumed and the water quality will meet the standard.This research has certain guiding significance for water environment management and hydraulic engineering impact post-assessment of Hongze Lake.
