农田水利现代化评价指标体系及评价方法研究

Study on Assessment Indicator System and Evaluation Method of Irrigation and Drainage Modernization

通过借鉴一些国际组织关于灌区(灌溉)现代化和我国关于水利现代化以及农村水利现代化的概念,给出了农田水利现代化的定义和内涵;结合现代化农田水利所应具备的民生、节水、生态、数字以及和谐农田水利五大特征,同时借鉴联合国粮农组织、世界银行以及国际灌溉排水委员会有关灌溉现代化评价指标的界定,遵循客观性、综合性和可操作性的原则,构建了我国农田水利现代化综合评价指标体系。参照《全国节水灌溉区划》,并根据各区域的自然地理特征及降水条件,最终将我国评价区域划分为东北区、海河和黄河中下游区、黄河上中游和内陆河区、淮河和长江中下游区、东南沿海地区和西南区六大评价区域,并给出六大评价区域和典型灌区农田水利现代化评价指标值。

With reference to the concept of irrigation modernization defined by some international organizations, as well as water mod- ernization and rural water modernization defined in China, this paper firstly raised the definition and connotation of irrigation and drainage modernization. Moreover, integrating with the humane, water saving, ecological, numerical and harmonious irrigation and drainage schemes a total of five features, this paper built the comprehensive assessment indicator system of irrigation and drainage modernization. These assessment index systems were finally validated and applied in the six assessment regions, all the provinces and some typical irrigation districts respectively. The results showed that, in the six assessment regions, the assessment value in Hal River and lower reach of the Yellow River basins is very high, around 0. 62, implying that it has already realized modernization. At the typical irrigation districts assessment, the assessment values of Yehe Irrigation District of Hebei Province and Yuyao City of Zhe- jiang Province are over 0. 80, implying that they have already realized irrigation and drainage modernization; The assessment values in Molimiao Irrigation District and Hetao Irrigation District that are both from Inner Mongolia are all 0. 69, implying that they have basically realized irrigation and drainage modernization; and the assessment value of Dujiangyan Irrigation District from Sichuan Province is low, only around 0. 58.
