英文摘要：

Due to its multi-target characteristics and the complexity of the solution,water and sediment regulation has always been the difficulty of the reservoir operation.This paper thoroughly analyzes the basic theory of water and sediment regulation of cascade reservoirs,describes the basic theory of reservoir optimal scheduling subsystem and reservoir sediment erosion and deposition calculation with their relationship as well,sums up the object＇s choice,objective function＇s establishment and consideration of constraints of water and sediment regulation,and investigates the conventional and intelligent calculating methods under optimization.And the key issues including subsystems＇ the coupling mechanism,connecting way of water and sediment and multi-objective approach,are discussed in detail.Besides some problems of water and sediment regulation among reservoirs to be explored in depth are proposed.A model for optimizating algorithm of water and sediment regulation,which can quantitatively describe combined cascade reservoir dispatch＇s rules of operation,efficiency indicators and sediment transport variation,realize the best coordination of flood control,utilizable capacity and sediment transport,will become the next focus of the study.
