封闭圩区水环境治理规划

Study on Water Environmental Amelioration Planning of Closed Polder Area

以江西省赣东大堤封闭圩区为研究对象 ,分析了圩区堤防采用垂直封闭截渗技术后对圩区内水环境的影响 ,建立了封闭圩区工程、环境综合规划数学模型 ,采用逐次逼近法 (MAP法 )将非线性问题线性化 ,求解得出了圩区的最优水面率和滞蓄水深、最优外排装机容量和内排装机容量以及大堤的最优封闭率。

The closed polder area of Gandong Embankment of Jiangxi Province is taken as a research object, and a comprehensive planning mathematic model including closed polder area engineering and environment is established through analysis of the impact on water environment after adopting technique of vertical closed seepage interception for the polder area embankment. By means of MAP in transferring non-linear model into linear model, the optimal water surface area ratio, water depth, pumping station capacity and the close ratio of the embankment of the polder area are solved. The mathematic model can provide a reference for the projects of similar polder areas.
