摘　　要：为了揭示水资源、经济和人口之间的关系,合理开发利用水资源,促进社会经济的可持续发展,选取鄱阳湖区11个县市为研究区域,利用GRACE卫星数据反演水量,采用生态服务评估方法计算了各县市水资源承载水平与水资源承载力,并对鄱阳湖区2010年水资源承载情况进行了评价。研究表明:鄱阳县、南昌县和进贤县水资源承载力较高,而德安县、星子县和湖口县较低;九江市市区水资源承载水平最高,南昌县、新建县、进贤县次之,德安县、星子县及其他县水资源承载水平较低;综合经济水平、文化水平、生态服务支撑功能与生态服务同化功能这四种因素,九江市市区、南昌县、星子县和湖口县单位水资源承载水平居高;新建县和九江市市区生态系统对经济发展产生污染的同化功能较差,其他9个县的同化功能均达标。In order to better reveal the relationship between water resources,economy and population,utilize water resources rationally,and promote the sustainable development of economy and society,water resources carrying capacity was researched indepth.Based on the new theories of water resources carrying capacity,water resources carrying level and water resources carrying capacity were calculated in 11 counties and cities of Poyang Lake area using the methods of GRACE water quantity inversion and ecological assessment,and the water resources carrying conditions of Poyang Lake area in 2010 were evaluated.The results suggested that the water resources carrying capacity in Poyang,Nanchang,and Jinxian counties is higher than that in Dean,Xingzi,and Hukou counties.The water resources carrying level is the highest in the urban area of Jiujiang,followed by Nanchang,Xinj ian and J inxian counties,while it is low in Dean,Xingzi,and other counties.Considering the factors of economic level,education level,eco-service support function,and eco-service assimilation function,the unit level of water resources carrying capacity is high in the urban area of J iujiang.Nanchang,Xinzi,and Hukou counties.The assimilation function of ecosystem on the pollution from economic development is bad in Xinjian county and urban area of Jiujiang,while it meets the standard in other 9 counties.
