摘　　要：在生态—经济系统基本理论的基础上,根据长江中下游地区湿地生态系统和社会经济系统的特点,构建评价指标体系,进行湿地自然生态系统和社会经济系统现状评价,同时也构建生态—经济系统耦合发展模型,利用协调度和协调发展度对长江中下游湿地地区生态—经济系统耦合发展水平进行分析,为区域未来可持续发展提供科学依据和决策支持.研究主要得出以下结论:1)研究区内鄱阳湖湿地区生态支撑力最高,其次是长江中游干流湿地区,洞庭湖湿地区最低.2)研究区内以武汉市为首的长江中游干流湿地区社会经济压力最大,其次是南昌市及洞庭湖湿地区,较小的是鄱阳湖的东部和长江下游湿地地区.3)通过协调发展度D分析发现:失调停滞区主要位于以长江干流一带,包括武汉市、洪湖市、公安县等,占研究区总面积的28.6%;过度调整区主要位于鄱阳湖东北部和洞庭湖东南部,和长江下游部分地区,占研究区总面积的53.2%;协调发展区以鄱阳湖西南部为主,还包括环洞庭湖西北部和安徽的贵池市和望江县,占研究区总面积的18.2%.This paper builds an evaluation index system according to characteristics of natural ecological system and social economic system,evaluates ecological support capacity and socioeconomic pressure,and analyzes driving factors with SPSS software.This will provide a scientific basis and decision support for regional sustainable development of the future.The following results are obtained.1)evaluation system was established of ecological support capacity and socioeconomy applied to the middle and lower reaches of Yangtze River wetland.Studies of ecological support capacity revealed that Poyang Lake wetland's ecological support capacity is the highest,followed by the Yangtze River wetland group,Dongting Lake wetland is the lowest,driving factors are NPP(net primary productivity),biological abundance and water conservation.2)Study of socioeconomic pressure revealed that the middle reaches of Yangtze River wetland group headed by Wuhan is the highest,followed by Nanchang and Dongting Lake wetlands,the east of Poyang Lake and the lower reaches of Yangtze River is the lowest.The driving factors are water consumption index,population density,urbanization rate and the emissions of pollutants.2)Study of coordination development degree Drevealed that the imbalance of stagnation zone mainly located in the Yangtze River area,including Wuhan,Honghu,Gong'an country and so on,is 28.6% of the study area;Excessive adjustment area mainly located in the northeast of Poyang Lake,the southeast of Dongting Lake and the lower reaches of Yangtze River,is 53.2% of the study area.Coordinated development area mainly located in southwest of Poyang Lake,also including the northwest of Dongting Lake,Guichi City and Wangjiang County of Anhui Province,is 18.2% of the study area.
