Abstract:: We built economical scale and population size assessment models to evaluate regional water resources carrying capacity of Chengdu and the districts, and the structural index model to evaluate structural state of water resources system. The results showed that the actual economical scale exceeded water resources maximum carrying capacity, and the actual population size is less than it. Carrying capacity index and coordination index of Chengdu are 1.734 9 and 0.672 4, respectively. From the district perspective, the economical scale, population size, carrying capacity index and coordination index showed the great differences. The carrying capacity index and coordination index of western district are lower than those of the eastern district, which means that its carrying capacity is stronger and the efficiency of water resource need be improved.
