| 摘要: |
| 针对黑河流域中游地区为追求经济发展而向黑河干流取水量过大导致的黑河下游地区地表水流量减少、生态环境恶化等问题，对该地区社会、经济等与水资源优化配置相关的资料数据进行收集、整理与分析，考虑地表径流随机性特征，构建考虑经济、社会、资源的灌溉水资源多目标优化配置模型，并使用层次分析法与线性加权法进行多目标问题求解。结果表明：将优化后的配水方案应用于黑河中游地区，其灌溉用水比实际节约3.358×108 m3，水分生产力提升0.380 kg/m3，用水费用节省3.89×107元，可以达到节水增产的目的，为该地区水资源管理部门提供一个满足可持续发展的农业水资源配置方案，同时，为类似地区的农业水资源优化配置提供方法依据。 |

| Abstract: |
| With the rapid development of economic in the middle reaches of Heihe River,the water consumption has kept increasing,which causes a decrease of surface water flow and a serious deterioration of the ecological environment in the lower reaches.In order to obtain sustainable agricultural water-allocation scheme of the Heihe River basin,a multi-objective optimization model taking full consideration of the random feature of surface runoff is developed.The model has three objectives including economic,social and resource,which can be solved by the method integrating analytic hierarchy process (AHP) and the linear weighting method.The results show that:Comparing with the actual water allocation scheme,there is 3.358×108 m3 reduction in the total water consumption,0.380 kg/m3 the water productivity increasement and 3.89×107 Yuan in the water costs.In conclusion,the optimization scheme can not only save irrigation water and increase crop yield in the study area,but also provide local water resources management department a reasonable allocation scheme to maintain the sustainable development of agriculture.Additionally,this study can provide method for managing agricultural water resources in the similar areas. |
