摘要:
通过数值模拟、经验公式分析等方法,研究了太湖西沿岸恢复湖滨带的水动力影响。适当宽度湖滨带的恢复不会改变大太湖风生流环流结构,对局部流速大小的影响范围仅100 m,入湖溇港行洪水位影响不超过1.2 cm。湖滨带有效阻断了沿岸泥沙输运,入湖溇港口门的泥沙淤积将得到改善。为保护湿地滩面,减少蓝藻入芦苇,建议湖滨带外侧修建生态式保滩防波堤。
Abstract:
By means of numerical simulation and empirical formula analysis, the hydrodynamic effects of restoring lakeside belt along the west coast of Taihu Lake were studied. The restoration of the lakeside zone with an appropriate width would not change the circulation structure of the wind-driven currents in the Great Taihu Lake, the impact on the local velocity was only 100 m, and the impact of the flood level into the lake port was no more than 1.2cm. The lakeside zone effectively blocked the transportation of sediment along the coast, and the sedimentation of the sediment into the port of the lake would be improved. In order to protect the wetland beach surface and reduce the introduction of blue algae into the reeds, it's recommended to build an ecological beach protection breakwater outside the lakeside zone.
