山東省濕地資源豐富,可分為自然濕地和人工濕地2類,自然濕地包括湖泊、海岸、沼澤、河口灣濕地,人工濕地主要為水稻田、水庫、池塘濕地等,濕地面積約為1.71萬km2。該文分析研究了山東省的濕地環境地質問題,并提出了工程措施和非工程措施2種防治措施。

　　濕地是位于陸生生態系統和水生生態系統之間的過渡性地帶,與人類的生存、繁衍、發展息息相關。濕地功能可分為直接的和潛在的功能,主要有提供水源、抵御洪水、蓄洪防旱、防止鹽水入侵、控制土壤侵蝕、降毒清污、調節氣候、維持生物多樣性、教育科研等功能[1]。山東省地處我國東

　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.
