长江流域水系复杂,防洪对象分布范围广,控制性水库的防洪调度目标具有多元化、分布多区域特征,如何科学运用水库防洪库容,有序兼顾各区域防洪是流域控制性水库群联合防洪调度的关键.选取溪洛渡、向家坝与三峡水库组成的水库群为对象,基于大系统分解协调原理,先通过逐次分解各防洪区域对溪洛渡、向家坝两库预留防洪库容的要求,在结合区域间洪水遭遇关联性分析的基础上,提出两库防洪库容在协调川江与长江中下游两区域防洪中的分配方案;同时对三峡水库的防洪调度方式深入优化,提出适当扩大对城陵矶防洪补偿库容分配方案.研究成果表明,联合调度方案可进一步减少长江中下游分洪量,对于提高整个流域防洪减灾水平,完善长江流域库群防洪调度体系具有重要意义.

The Changjiang River possesses a complex river system and widely distributed flood protection objects. As the multi-nurpose of flood control operation for its leading reservoirs involving a wide range of regions, the key for joint flood control operation of leading reservoirs in the river basin lies on utilizing flood control storage reasonably and orderly giving consideration to overall plans flood control for related re?gions. Taking a group of reservoirs, Xiluodu, Xiangjiaba and the Three Gorges as the object, this paper proposes flood control storage allocation plan for coordinative flood control of the Chuanjiang and the Changjiang rivers by using the principle of large-scale system decomposition-coordination, through succes?sively decomposing the different demands for the flood control storage of Xiluodu and Xiangjiaba reservoirs by the flood protection objects in every region,and analyzing flood strike patterns for the Chuanjiang River and the midstream of the Changjiang River. Further, a flood control operation mode of the Three Gorges reservoir was optimized and an allocation plan was raised by increasing flood control compensation storage for Chenglingji, concerning impoundment effect from upstream Xiluodu and Xiangjiaba reservoirs. The re?sults show that the joint operation mode can further reduce flood diversion capacity of the lower-middle reaches of the Changjiang River,which is highly significant for increasing flood control capacity and improv?ing comprehensive group-reservoir flood control system of the whole Changjiang River Basin.
