长江中游流量与航道维护尺度关系研究

Study on the Relationship between the Flow Discharge and the Channel Maintenance Dimension in the Middle of Yangtze River

提出了一种构建宜昌流量与中游航道维护尺度关系的方法.利用长期观测资料,通过建立宜昌流量与中游水位站点水位回归方程,结合实际测图资料,分析推导出宜昌流量与长江中游长河段航道尺度对应关系,为优化三峡水库调度方案、合理确定长江中游航道维护尺度提供理论基础.

This paper proposes a construction of Yichang flow discharge with the middle channel maintenance dimension method. Using long-term observation data, by establishing the water level regression equation of Yichang flow discharge and middle site level, combined with the actual mapping data, the corresponding relationship between Yichang flow discharge and long-distance river maintenance dimension of middle channel of Yangtze. The results of this study could provide the theoretical basis on the optimization of the three gorges reservoir scheduling scheme, reasonable channel maintenance dimension in the middle reach of Yangtze River.
