Abstract 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.
