摘要
长江上游水库群是长江流域防洪工程体系的重要组成部分,承担着水库所在河流、川渝河段以及长江中下游的防洪任务。长江流域面积广大,水系众多,洪水地区组成与遭遇十分复杂,防洪需求众多,防洪对象分散,且要兼顾发电、航运、供水、生态、库区安全等多种因素,水库群防洪调度面临大规模、多区域、多层次等协同调度技术难题。以长江上游25座控制性水库为研究对象,基于防洪格局和防洪任务将水库群防洪调度划分为核心、骨干和群组水库,阐明了水库群多区域协调防洪的调度节点和角色定位,提出了兼顾"时-空-量-序-效"多维属性的模型功能结构,构建了长江上游水库群多区域协同防洪调度模型,并在长江流域防洪调度形成示范应用,以挖掘长江上游水库群防洪调度潜力,进而提升长江流域防洪调度管理水平。
As an important part of flood control project system in the Changjing River Basin,the reservoir groups in the upper reaches of Changjiang River undertake the important tasks of flood control in the rivers where the reservoirs located,the Sichuan-Chongqing reaches and the middle and lower reaches of Changjiang River.However,the Changjiang River Basin has a large area and numerous water systems,the composition and encounter of floods are very complex.In addition,the flood control demands are numerous,the flood control objects are scattered,and various factors such as power generation,shipping,water supply,ecology and reservoir security should be taken into account,which make the collaborative flood control of reservoir groups face large-scale,multi-regional and multi-level technical problems.In this paper,taking 25 controlled reservoirs in the upper reaches of Changjiang River as research objects,the reservoir groups were divided into core,backbone and group reservoirs based on the flood control tasks and pattern.The operation node and role orientation of multi-regional coordinated flood control of reservoir groups were expounds.Then,a functional structure considering the multi-dimensional attributes of"time-space-quantity-ordinal-efficiency"was proposed,the multi-regional coordinated flood control operation model of reservoir group in the upper reaches of Changjiang River was constructed.Finally,a demonstration was formed in flood control operation of the Changjiang River Basin,so as to explore the flood control potential of reservoirs in the upper reaches of Changjiang River and improve the flood control management of the Changjiang River Basin.
