| 中文摘要: |
| 以宝鸡峡灌区为研究对象,在田野调查和总结国内外研究成果基础上,提出了经济用水模式的概念,并从水资源总量控制约束、灌溉节水模式、经济配水模式三个方面对其框架体系进行了研究;在研究过程中,应用定性与定量相结合的方法,建立了基于因子权重法的、目标函数为经济、社会、生态综合效益最大化的宝鸡峡灌区经济用水多目标规划数学模型,并对其进行了计算和分析,得出了灌区水量经济调配模式。该模式在灌区平水年(P=50%)缺水量为0.0398×108m3,可节约用水0.3972×108m3;枯水年(P=75%)灌溉缺水量为3.2858×108m3,可节约用水3.2035×108m3。与灌区历史灌溉数据比较,该模式吻合率高,适用性强。 |

| Taking Baojixia Irrigation District as a research object based on on-the-spot investigation and research both home and abroad, the concept of economical water-use model is proposed, and the frame system is conducted from three aspects: total quantity control of water use constraints, water-saving irrigation model and economical water distribution model.In the process of study, combining qualitative and quantitative analysis, a multi-objective programming mathematical model whose object function is to maximize economic and social benefits is set up based on the factor weight method.In this model at normal years (P=50%) water shortage is 0.0398×108m3, water saving 0.3972×108m3;at dry years (P=75%) water shortage is 3.2858×108m3, water saving 3.2035×108m3.With the irrigation district history data comparison, the model has high matching rate and applicability. |
