| 摘 要： | 对比分析了对大型灌区的常用评价方法,指出这些方法存在的主要缺点是评价中各指标权重的确定易受人们主观因素的影响.改进突变理论避免了评价各指标权重的确定问题,从而相对减少了人们主观因素的影响.对突变理论综合评价方法进行了改进,通过调整突变理论评价综合值的方法,克服了综合评价值过高和过于接近的问题,提高了其评价结果的分辨水平.将改进突变理论综合评价方法运用于大型灌区运行状况综合评价中,以陕西省大型自流渠灌区洛惠渠为实例进行验证,洛惠渠灌区在2009,2010,2011,2012年的评价值分别为0.060 5,0.265 7,0.549 1,0.660 1,运行状况等级分别为中等,良好,良好,良好.其评价结果与改进TOPSIS法的结果基本一致,都随着时间的推移,洛惠渠灌区评价级别从中等逐渐变为良好,运行状况越来越好,这也符合洛惠渠灌区的客观实际和发展规律,且该方法计算简单、可靠性高,可为大型灌区运行状况综合评价提供一种新方法.

| Abstract: | Usual methods for evaluating operational conditions of a large-scale irrigation district are reviewed. The main drawback in these methods is that the weight for each index of evaluation is susceptible to be affected by subjective factors and improved catastrophe theory potentially can determine the weight for each index properly to reduce the influence of subjective factors. Thus, in this paper, a comprehensive evaluation method is proposed based on the catastrophe theory by improving and adjusting the approach for determining comprehensive evaluation values to overcome the problem that comprehensive evaluation values are too high and too close each other so as to achieve a better resolution of evaluation. The comprehensive evaluation method is applied in assessment of the operational conditions of a large-scale irrigation district, namely validated by Luohuiqu Irrigation District, a large-scale gravity canal system in Shaanxi Province. As a result, the comprehensive evaluation values are 0.060 5, 0.265 7, 0.549 1 and 0.660 1, respectively, in year 2009, 2010, 2011 and 2012, accordingly, the operational conditions are fair, good, good, good. The evaluation results are basically in accordance with those by the traditional improved TOPSIS method. With time passing, the operational conditions of the district will become good from fair gradually, showing the conditions get better and better. This conforms to the objective reality and development rule of the district. Additionally, the method is simple in calculation and with high reliability, can be a new method for comprehensively assessing operational conditions of a large-scale irrigation district. |
