摘要
城陵矶地区是长江中下游洪灾最频发的区域之一,是长江水库群防洪的重点保护对象.金沙江下游乌东德、白鹤滩、溪洛渡、向家坝4 座梯级水库与三峡水库组成的巨型水库群防洪能力巨大,显著改变了流域防洪调度格局.在概括分析城陵矶地区防洪需求,回顾三峡水库对城陵矶地区防洪补偿控制水位不同阶段成果的基础上,剖析了优化防洪补偿控制水位的研究要点,研究了金沙江下游梯级防洪库容投入情况,进而明确了提高防洪补偿控制水位的有利条件.研究结果表明:在三峡水库水位达到城陵矶防洪补偿控制水位 158.00 m后,金沙江下游梯级水库在预留40.93 亿m3 防洪库容的基础上,尚有 30 亿～60 亿m3 富余防洪库容可配合运用,为进一步提高三峡水库对城陵矶防洪补偿控制水位创造了良好条件.
Abstract
Chenglingji Area is the most frequent flooded area in the lower-middle reaches of Changjiang River,and is the key flood control protection object of reservoir group in Changjiang River.At present,the huge reservoir group of Wudongde,Baihetan,Xiluodu,Xiangjiaba and Three Gorges has huge flood control capacity,which has significantly changed the flood control pattern of Changjiang River Basin.In this study,we systematically summarized the flood control requirement of Chenglingji Area,and briefly reviewed the achievements of flood control compensation level of Three Gorges Reservoir to Chenglingji Area in different stages,and then analyzed the further research points and flood control storage of cascade reservoirs in the lower reaches of Jinsha River,and finally explicated the favorable conditions for further improvement of this control level.The results show that after the water level of Three Gorges Reservoir reaches the Chenglingji flood controlled level of 158.00 m,on the basis of 40.93×108 m3 re-served flood control storage,there is still 30×108～60×108 m3 remaining flood control storage of cascade reservoirs in the lower reaches of Jinsha River,which creates a favorable condition for further improvement of the flood control compensation level.
