摘要
文章指出长江沿岸发育了大量湿地,类型多样、分布广泛,各具特色,包括湖泊、沼泽、滩涂和人工湿地.这些湿地在维系长江生态平衡方面,发挥了重要的生态、经济和社会功能.快速的人口增长、经济发展和全球气候变化等对湿地自然生态系统形成巨大压力和威胁,造成大量湿地退缩、咸化甚至消亡.加强现有湿地的保护和构建人工湿地是目前湿地治理的主要措施.
Along the Yangtze River there are large number of wetlands of various types,including lakes,swamps,bottomlands and artificial wetlands.These wetlands distribute in a wide range,with different features,and lead an important role in ecological,economic and social functions to sustain the ecological balance of Yangtze River.Wetlands ecosystems are under a great pressure and threat from rapid growth of population,economic development and global climate change,which result in the shrinking and salty or even disappearance of wetlands.As the main administrating measures,we propose to enhance the protection of present wetlands and the construction of artificial wetlands.
