公开种基于情景的水与生态空间分区多目标优化决策方法，包括步骤：1)确定决策目标和子目标；2)初步选择决策变量集以及约束集；3)进行空间分区，规划各个时间阶段；4)根据空间分区得到的不同空间子区域，选择与其相对应的局部变量和局部约束，建立空间分区优化模型；5)根据决策变量重要性选取其状态值个数，并对各决策变量赋值，构建不同空间子区域上的情景决策方案；6)对各子区域上的情景决策方案进行排序，并分别从排序靠前的若干情景决策方案进行组合；7)从组合后得到的总情景决策方案中选出最佳情景决策方案；8)针对下个时间阶段，以上个时间阶段作为初始状态，重复步骤4)至7)，直至所有时间阶段完毕。 The invention discloses a spatial-division multi-objective optimized decision-making method based on scenarios. The method comprises the following steps: (1)determining a decision-making objective and a subobjective; (2)preliminarily selecting a decision variable set and a constraint set; (3) dividing a space and planning each time phase; (4) obtaining different space subregions according to spatial division, selecting local variables and local constraints corresponding to the space subregions, and establishing a spatial-division optimization model; (5) selecting the status value number of a decision variable according to decision variable importance, and carrying out assignment on each decision variable to build scenario
