- 摘要:
- 以成都市及其各区县为研究对象，评估成都市水资源承载力及其利用水平，并探究其内部区域差异。评价结果表明：从成都市总体情况来看，成都市实际经济规模超过水资源系统最大承载力，而实际人口规模小于水资源系统最大承载力，其承载力指数和协调指数分别为1.734 9，0.672 4，水资源的开发利用略有超载，可持续性不高；从区域内区县来看，其水资源可支撑的经济规模、人口规模，承载力指数和协调指数上呈现出较大差异。西部区县的承载力指数低于东部区县，水资源系统受到的压力较小，承载能力较强；西部区县协调指数同样低于东部区县，说明西部区县水资源利用方式有待改善，利用效率有待提高。
- 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.
