　　湿地是位于陆生生态系统和水生生态系统之间的过渡性地带,与人类的生存、繁衍、发展息息相关。湿地功能可分为直接的和潜在的功能,主要有提供水源、抵御洪水、蓄洪防旱、防止盐水入侵、控制土壤侵蚀、降毒清污、调节气候、维持生物多样性、教育科研等功能[1]。山东省地处我国东

　Natural resources of wetlands are very rich in Shandong province.They can be divided into two types as natural wetland and artificial wetland.Natural wetlands are mainly composed of lakes,coastal areas,estuaries and wetlands in gulf,while artificial wetlands are mainly composed of paddy fields,reservoirs and ponds wetlands.The total square of wetland is about 17100km 2.On the basis of analyzing and studying geological and environmental problems of wetlands in Shandong province,two kinds of prevention and control countermeasures,such as engineering and non-engineering countermeasures are put forward in this paper.
