| 摘 要： | 在灌区水资源开发利用状况评价中，评价指标体系的建立和评价因素权重的确定非常重要。针对评价因素权重确定中的困难，把突变理论运用到灌区水资源开发利用状况评价中，利用突变理论在多准则评价决策中的优点，避免人为确定权重的主观性。具体实施步骤是首先对多层评价目标进行分解，在将底层评价指标进行标准量化后，运用不同突变模型的归一公式进行计算，从而得到水资源开发利用状况突变级数值，实现对灌区水资源开发利用状况的综合评判。实例分析表明，该评价方法是合理、可行的，相对于以往评价方法，突变理论评价法无需确定指标权重，减少人为主观因素，且计算简便，为灌区水资源开发利用状况评价提供了新的思路。

| Abstract: | In the comprehensive assessment of water resources utilization in irrigation districts,the establishment of assessment system and the determination of weights are both important and difficult.Based on the difficulty in defining weight values,the catastrophe theory is used in the comprehensive assessment,and the advantage of catastrophe theory in the multi-rule assessment is used to avoid the subjectivity of artificial weights.The concrete steps of practice are to analyze the multi-layer assessment object fi... |
