摘　　要：为解决传统低影响开发(LID)设施空间布局时受主观因素导致径流控制成本高及控制效果差的问题,以山西省原平市经济开发区为例,对比分析了NSGA-Ⅱ、CCMO、NSGA-Ⅲ与MOPSO等4种多目标优化算法对LID设施布局比例优化问题的求解结果与性能评价指标,以此提出研究区域的最佳方案。结果表明,CCMO算法较为适合优化LID布设比例。根据不同重现期,选择近期、中期和远期三种方案,建设成本分别为1 724×10^(4)、1 972×10^(4)、2 448×10^(4)元,在不同重现期下的平均洪峰流量削减率分别为72.0%、81.2%、90.8%。多目标算法优化LID设施布局后,通过较低的LID设施建设成本达到较优的洪峰削减效果,为缓解城市内涝提供决策支持。The GRMS Cloud is a set of fully domestic simulation platforms that are now widely used.However,it is still insufficient for international river research and application.This paper analyzes the spatial and temporal characteris-tics of hydrological elements in the Mekong River Basin.Mann-Kendall method is used to calculate the significance levels of the trends of each element.The applicability of the GRMS Cloud in the Mekong River Basin is evaluated.In addition,the contribution of precipitation and potential evapotranspiration changes to runoff is quantified by detrending treatment and relative contribution method.The results show that the trend of precipitation and potential evapotranspiration changes in the Mekong River Basin between 1979 and 2014 was not significant,but the runoff showed a significant decreasing trend.The GRMS Cloud simulated runoff in the Mekong River Basin well in each de-trending scenario.In addition,in the Mekong River Basin,precipitation change is the dominant factor affecting runoff change,while the effect of potential e-vapotranspiration is more minor.This study contributes to the understanding of runoff variability and its characteristics in the Mekong River Basin and extends the applicability of the GRMS Cloud.
