摘要:

城市水资源优化配置后,对配置方案进行后效和谐性评价以确定配置模型及配置方案的适应性具有重要意义,同时也是促进人水和谐的有效途径之一。影响水资源配置系统和谐性的因素繁多,评价方法也较多,但各类方法在评价过程的模糊性、指标权重的模糊性及评价精度方面均有不足。论文将区间数与层次分析法相结合,用区间数表示各指标表征值及专家的评价意见,对榆林市榆阳区水资源配置系统的后效和谐性进行评价研究,采用区间数特征根法求出各个指标层因素的区间权重,并进行一致性检验。研究结果表明,经水资源优化配置后,榆阳区水资源配置系统的和谐性整体提升,且系统内的各子系统和谐性也均有不同程度的提升;与目前常用的评价方法相比,区间层次分析法体现了评价过程的模糊性、权重的模糊性与评价精度,使评价结果具有柔性化特征,更加合理可靠。

Abstract:

After optimally allocating the urban water resources, it is of great importance to evaluate the post-allocation harmony of the water resources system in order to determine the adaptability of the allocation model and the allocation schema. Meanwhile, it is one of the effective ways to promote the harmonic relationship between human and water. There are many factors influencing the harmony of water resources system which therefore lead to a variety of evaluation methods. Current methods all suffer from the vagueness of the evaluation process and the vagueness of the index weight. This paper evaluated the post-allocation harmony of water resources system in Yuyang District of Yulin city by analytic hierarchy process coupling with interval number which represents the characterization value of indices and experts’ options. This method employed the characteristic root of the interval number to obtain the interval weights for each layer of factors. Then, the consistency checking was conducted. The results showed that after the optimal water resources allocation, the overall harmony of water resources system in Yuyang District upgraded, as well as the subsystems within the system. Comparing with other common used evaluation methods, the method of analytic hierarchy process coupling with interval number could reflect the vagueness in the process of evaluation and the vagueness of the index weight, which made the evaluation results more flexible, reasonable and reliable.

Key words: harmony evaluation, interval analytic hierarchy process, interval number, water resources allocation system
