摘要
湿地在生态系统中的功能和价值已得到公认 ,但对湿地的破坏却因种种原因仍在继续。根据国际上对湿地的不同定义 ,讨论了湿地定义对湿地保护的重要性 ,同时结合我国一些地区的研究成果 ,指出湿地保护应以保护从陆地到水体的过渡带为主 ,而将水体本身以及诸如稻田一类的人工系统包括在湿地中 ,则会对湿地保护带来负面影响。
Although the function and value of wetlands in the ecosystem have been well recognized, wetlands destruction is still ongoing for various reasons. In this paper, we discussed the importance of wetland definition in wetland protection according to different definitions proposed around the world, and pointed out that the focus of wetland protection should be on protecting the transitional zone between the terrestrial and aquatic systems, and defining general water surface as wetland has negative impact on wetland protection. Finally, we discussed the hydrologic criteria in wetland delineation according to 7 criteria used in the US.
