摘要: 采用河势分析和实体模型试验相结合的方法,研究论证了橘子洲综合治理工程对河段河势、防洪及重要涉水建筑物等方面可能产生的影响,并就治理工程对环境的影响进行了分析。研究结果表明,工程兴建有利于洲、水、城市相互融合,易形成良好的区域生态环境,但对附近河段防洪水位、汊道分流比、湘江一桥桥墩局部冲刷会带来一定不利影响。为维护湘江的健康,针对不利影响产生的原因,对治理方案提出了优化改进措施,为工程决策和设计提供了参考依据。

Abstract: Juzizhou Islet is located in the middle of Changsha river stretch of Xiangjiang River. Its disordered current status has a strong impact on the ecology and environment of the Changsha City and so this reach urgently needs to be regulated. In combination with river regime analysis and physical model tests, the authors research and demonstrate the possible influence of integrated regulation works for bank line of Juzizhou Islet on the river regime, flood control, important waterrelated buildings etc., and analyze the affect of these works on the environment. Research result indicates that the construction of these works is favourable to the mutual fusion among the islet, water and city, and is easy to form a favorably regional ecology environment, but it will have negative effects on the flood control level nearby the river stretch, the diversion ratio of branching channels, and the local erosion of No.1 Xiangjiang Bridge. In order to maintain the rivers health, the authors put forward the optimized improvement measures for regulated schemes according to the reasons caused by these negative effects, which provide the reference for the determination and design of works.
