摘　　要：文章从经济系统、城镇化系统、生态系统与水资源系统四个方面建立指标体系,运用因子分析法评价了江西省宜春市的水资源承载力。结果发现,宜春市水资源承载压力总体呈现曲折上升趋势。其中公共因子中的经济城镇因子、产业需水因子与水资源承载压力之间为正相关关系,水资源供应因子和水生态因子的不同二级指标与水资源承载压力之间的相关性存在异质性。据此,在经济发展和城镇化进程不断加快的同时,需优化产业结构,提高人们节水意识,加强污水排放监管,提高污水处理能力,保护水生态环境,进而提高水资源承载力。An index system from four aspects of economic system,urbanization system,ecosystem and water resources system is established to evaluate the water resources carrying capacity of Yichun city in Jiangxi province by using factor analysis method.The results show that the carrying pressure of water resources in Yichun city tends to wind upward.Among the public factors,economic town factor,industrial water demand factor and water resources carrying pressure are positively correlated,while the correlation between water resources supply factor and water ecological factor and water resources carrying pressure is heterogeneous.Therefore,in the development of economic growth and urbanization,it is necessary to optimize the industrial structure,improve people’s awareness of water saving,strengthen the supervision of sewage discharge,and improve the sewage treatment capacity to protect the water ecological environment,thus improving the carrying capacity of water resources.
