| 摘 要： | 在耕地保护和粮食安全的国家目标背景下,以水土资源耦合和生态保育为理念,以黄土台塬区为例分析典型干旱半干旱区的水资源条件,基于遥感和GIS数据,采用帕累托(Pareto)寻优原理建立了区域水资源多目标优化配置(RWRMOA)模型,通过对水利工程改造建设和粮食作物种植组合优化等方法,进行水资源优化并进行空间差异分析,旨在提高区域粮食产量和节约水资源。研究结果表明:1黄土台塬区水资源供需分布不均,渭河、黄河两岸、渭南和豫西部分区域水资源挖潜潜力较大;2占研究区总面积63.87%的董志塬、山西峨眉塬及豫西等区域,只要适当增加灌水量便可提高产量;3占区域总面积约30%的渭南和豫西等区域,能在经济效益最优的前提下满足作物非充分灌溉水量;4关中地区井渠结合的灌溉方式效益较高,提水灌区经济效益较差;5井渠结合和引水灌区可满足非充分灌溉条件,主要分布在豫西和晋中等区域,而纯井灌区不能满足,其它可用集雨灌溉来补充,集雨工程可在作物需水期补灌两次,可通过结合集雨补灌,缓解水资源短缺问题。

| Abstract: | Based on RS and GIS data, here we establish a Regional Water Resource Multi-objective Optimization Allocation (RWRMOA) model. Using water conservancy construction and reconstruction methods such as crop planting structure optimization, optimization of water resources and spatial variance analysis, we aimed to improve regional food production and conservation of water resources. Three types of water source projects, and the available water supply and cost of each type were included. We found that water resource supply and demand differs over time(seasons)and space(regions)across the Loess Platform, location in China. The banks of the Weihe and Yellow Rivers, some areas in western Henan and Weinan city have great potential in using water resources. It is appropriate to increase the amount of irrigation to increase production on the Dongzhi Plateau and Emei Tableland in Shanxi and western Henan. These areas accounted for 63.87% of the total area. Approximately 30% of the area has an economical method to meet crop demands under the premise of non-sufficient irrigation(mainly in Weinan City and western Henan). Drainage combination wells are high efficiency and beneficial irrigation, but the economic benefits of water pumping irrigation are poor across Guanzhong. Water resources can meet deficit irrigation in drainage combination wells and water diversion irrigation regions(e.g. in western Henan and Jinzhong), but the well irrigation cannot meet demands. Rainwater harvesting irrigation is available to increase the supplement and a combination of collected rainwater irrigation and rainwater works can alleviate significant water requirements during drought. |
