摘要水资源短缺风险评价具有不确定性。建立了基于可变模糊集的水资源短缺评价模型，合理确定了各层次简单指标的相对隶属度和函数以及标准区间。利用该模型对长江三角洲地区（包括上海和南京）和首都圈地区（包括北京和天津）的水资源短缺风险进行了评估。结果表明，该模型合理地确定了各相关指标在排序范围内的隶属度。更重要的是，该模型是灵活的，适应性强，诊断不同生态条件下的缺水风险。
ABSTRACT Water shortage risk assessment is full of uncertainty. Hence a water shortage assessment model was developed based on the variable fuzzy set, which reasonably identifies the relative membership degree and function of simple index and standard interval of each level. The model is used to assess water shortage risks in the Yangtze River Delta (which comprises the cities of Shanghai and Nanjing) and in the Capital-area of China (including the cities of Beijing and Tianjin). Results show that the proposed model rationally determines the membership grade in the range of rankings for all related indicators. More importantly, the proposed model is flexible and adaptable for diagnosing water shortage risks for different ecological conditions.
