摘　　要：基于水资源承载能力概念和通辽市水资源利用基本情况,构建了水资源可承载能力评价的递阶层次指标体系.结合可变模糊集理论,建立了通辽市多层次水资源承载能力可变模糊评价模型,并对通辽市各行政区现状年和规划年的水资源承载能力进行评价.结果表明,通辽市水资源承载能力全区均较弱,产业结构不合理和水资源重复利用率低是造成水资源承载能力低的主要因素.对2020规划年的评价结果显示,节水条件下通辽市水资源承载能力有所改善,但基本仍较弱,需通过合理调整产业结构、提高水资源利用率等来提高水资源承载能力.A multi-hierarchy variable fuzzy evaluation model for carrying capacity of water resources in Tongliao City is established to evaluate each district in current year 2013 and the planning year 2020 based on the concept of water resources carrying capacity,the variable fuzzy set theory and utilization status in the city.The result for 2013 shows that unreasonable industrial structure and low water reuse rate account for the generally weak carrying capacity;while the result for 2020 indicates that the city’s water resources carrying capacity will be improved a little under water-saving condition,but basically still weak.Therefore,only by rational adjustment of industrial structure and improvement of water use efficiency can the carrying capacity be improved.
