摘要
灌溉管理节水发展水平评价是制定区域节水灌溉发展规划的重要决策依据。该文采用定量指标和定性指标相结合的方法建立了包括组织管理、工程管理、用水管理和经营管理4个层次16项指标的区域灌溉管理节水发展水平综合评价体系,在此基础上构建了四川省灌溉管理节水发展水平综合评价模型;引入熵权法和层次分析法计算各评价指标权重,提高了权重确定的科学性与客观性。以四川省21个市州(区域)为研究对象,利用模型通过形成决策矩阵、确定权重、建立加权决策矩阵、计算各评价对象与理想解的相对贴进度,由此得到四川省不同区域灌溉管理节水发展水平。结果表明:四川省全省灌溉管理节水发展处于"一般"水平;21个区域中,成都、德阳处于"好"水平,攀枝花、绵阳、资阳、乐山处于"较好"水平,自贡等10个区域处于"一般"水平,广元、内江处于"较差"水平,甘孜、阿坝、凉山处于"差"水平;以上结果符合四川省灌溉管理节水发展的实际情况;模型对于四川省灌溉管理节水发展具有较强的实用性。
The evaluation of the water-saving development level of irrigation management is an important foundation to make water-saving irrigation development plan in a region. This paper established a comprehensive evaluation system for the development level of water-saving irrigation management, including 4 levels and 16 indicators of water use management, engineering management, organization management and business management, and built a comprehensive evaluation model of the water-saving development level of irrigation management at the basis of approaching the ideal solution. Furthermore, the entropy method and analytic hierarchy process were introduced to calculate the weight of each evaluation index, which improved science and objectivity to determine the weights. Taking 21 regions in Sichuan Province as the research object, the weights were determined and the weighted decision matrix was established by forming a decision matrix using the model, and the relative similarity degree of each evaluation object and the ideal solution were calculated, then the water-saving development level of irrigation management of different regions in Sichuan Province was obtained by using the relative similarity degree. The result shows Sichuan Province＇s water-saving development level of irrigation management evaluation is ＂normal＂, and water-saving development level of irrigation management in each region is consistent with its situation of economic development, participation of water users, and intensity of reform promotion. So, the most developed regions, such as Chengdu, Deyang are ＂good＂; Panzhihua, Mianyang, Ziyang and Leishan in a ＂relatively good＂ level; Zigong etc. in ＂normal＂ level; Guangyuan and Neijiang in a ＂relative poor＂ level, and the least developed regions： Ganzi, Aba and Liangshan in a ＂very poor＂ level. The results are accord with Sichuan Province＇s actual situation of the water-saving development of irrigation management. Therefore, the model has a strong practicality to evaluate the
