摘　　要：采用GIS技术、遥感技术、资料与图件收集和定量分析模型等相结合的综合研究方法,对鄱阳湖区1971-2010年来的水域变化进行分析。结果表明:近40年来鄱阳湖区水域面积呈减少趋势,其中水面面积变化表现为逐步降低再升高的"V"形趋势,滩涂、沼泽地面积分别为上升再降低的倒"V"形的趋势,草洲面积在1971-1985年间大幅度减少,后保持较稳定;水域面积变化在空间上也不尽相同,表现为南部变化快,北部、尤其是西北部变化较小,空间变化主要受自然因素影响。定量分析影响鄱阳湖水域因素得出,鄱阳湖水域的变化和社会经济指标没有显著的相关性,主要是受"围湖造田"和"平垸行洪、退田还湖"等政策的影响。In order to analysis the water area changes and protection of the water resources and ecological environment in Poyang Lake region,this paper adopts the comprehensive research method of GIS,remote sensing,information and map collection,the quantitative analysis model to Poyang Lake and the surrounding 11 counties（city,area） in recent 40 years to analyze the water area change and its＇ influencing factors.The results showed that the water area showed a decreasing tendency from 1971 to 2010,but the water changes experienced gradually decreased and then increased as the shape of ＂V＂ trend,and beaches,wetlands respectively up and down inverted ＂V＂ shape trend,grassland in 1971-1985 years after decreasing substantially remained relatively stable area.Water changes in space are not the same,the South changes quickly,but the north,especially northwest changes less,spatial variation is mainly affected by natural factors.Quantitative analysis of influence factors showed that Poyang Lake water area change have no significant correlation with the changes of social economic indicators,is mainly affected by the policies of ＂reclaiming land from Lake＂ and ＂returning farmland to Lake＂.Finally,countermeasures of the water protection in Poyang Lake region were put forward.
