【摘要】 在对水资源系统组成和结构分析的基础上,运用大系统优化理论建立了区域水资源系统多目标优化配置数学模型,包括水源优化调度、水量优化分配和调度分配迭代3个子模型。水源优化调度模型的求解采用轮库迭代方法和动态规划方法,水量优化分配模型的求解采用大系统分解协调中的D-W分解原理。对江苏省连云港市区水资源优化配置问题进行了研究,建立并求解了优化配置模型,结果表明,该市各区在2020规划水平年工业、农业、生活和环境部门都将出现不同程度的缺水情况。更多还原

【Abstract】 On the basis of analyzing the composition and structure of a water resources system,a multi-objective optimal allocation model was established for regional water resources systems by applying large-scale system optimization theory.The model contains three components: the water source optimal operation model, the water quantity optimal allocation model,and the iterative operation-allocation model.The solution of the water source optimal operation model can be obtained using the iterative method of alternating reservoirs and the dynamic programming approach.The water quantity optimal allocation model is solved with the DW decomposition method of large-scale decomposition coordination theory.As an example,the optimal allocation of water resources in the Lianyungang urban district was investigated.An optimal allocation model was set up and the allocation results were obtained.The results indicate that water shortage will occur to different degrees in industry,agriculture,the domestic water supply and the natural environment by the year 2020.更多还原
