摘　　要：应用"全国生态环境十年变化(2000—2010年)遥感调查与评估项目"研究成果,分析了长江中下游湿地10年间的生态保护现状和景观格局变化,并应用CLUE-S模型预测了长江中下游湿地保护未来5~15年的发展趋势。结果表明:2000—2010年,长江中下游湿地构成比例发生了较大变化,自然湿地萎缩严重。其中,洞庭湖水域面积下降了63.4 km^2,降幅为11.9%;鄱阳湖的水域面积下降了176.3 km^2,降幅为13.4%。即使在优化情景下,未来5~15年长江中下游城市群湿地面积的持续减少趋势仍难以遏制。To assess the impact of a Rise of Central China Strategy＂ and “ Yangtze River Economic Belt Strategy”,the current situation of ecological protection and change of landscape pattern in the Yangtze River wetlands between 2000-2010 were analyzed in this paper on base of the research achievements of Remote Sensing Survey and Assessment Project for National Ecological ＆ Environmental Changes in Ten Years （2000-2010） . The results indicated that the proportion of the Yangtze River wetlands changed greatly from 2000 to 2010, and natural wetlands seriously decreased. On the basis of current situation analysis, challenges for the Yangtze River wetlands in the next 5 to 15 years were forecasted by applying CLUE-S model. The predication results suggested that the wetland area in Yangtze River would continue to decrease even under the optimal scenario.
