长期以来城陵矶控制水位既是堤防设计水位又是蓄洪工程调度运用水位,这一直是长江中游防洪问题争论的焦点.从分析现有江湖关系条件下的长江洪水特征出发,以长江中游防洪体系既定的布局为基础,结合三峡水库的调节作用,根据模型模拟结果和实际水情,提出将堤防设计水位与蓄洪工程调度水位分开,近期莲花塘防洪设计水位采用历史最高水位35.80 m、蓄洪工程调度水位采用34.4～35.80 m为宜.

The control water level of Chenglingji is not only for design of dikes but also for regulation of flood storage project for a long time, which has always been a heated debate focus in flood control of middle Yangtze River. From the aspect of analyzing characteristics of flood control of Yangtze River under current the River-lake relation, based on vested layout of flood control system of middle Yangtze River, combining the effort of regulation of Three Gorges Reservoir, the separation of water level for design of dike and regulation of flood storage project is put forward according to simulation results and practical water regime. The historical highest water level 35.80 m is adopted to be the present flood control water level of Lianhuatang, and the water level for regulation of flood storage project should be 34.4 m to 35.80 m.
