摘要 湿地是由陆地系统和水体系统相互作用形成的自然综合体.湿地具有的特殊性质--地表积水或土壤饱和、淹水土壤、适应湿生环境的动植物--是湿地系统既不同于陆地系统也不同于水体系统的本质特征.湿地具有水文功能、生物地球化学功能和生态功能.一般认为湿地是二氧化碳的"汇"和全球尺度上的气候"稳定器",在全球环境变化研究中具有重要意义.目前,要加强对湿地系统的基础理论研究,对湿地的概念、性质、功能,以及湿地科学的发展方向要有一个明确的认识. Wetlands are formed by the interaction between terrestrial system and aquatic system. Wetlands are among the world s most productive environment. They are cradles of biological diversity, providing the water and primary productivity upon which countless species of plants and animals depend for survival. Wetlands have hydrological function, biogeochemical function and ecological function. The interactions of physical、bio-logical and chemical components of wetland, such as soils, water, plants and animals, enable the wetland per-form many vital functions. Wetland research is very important in the research of global environment change because wetlands act as a 'sink' of carbon and climate 'stabilizer' on global scale. At present, the basal theory research of wetland system should be strengthened. We should take great effort to further understand the definition, property and function of wetlands. The developmental tendency of wetland science should be clear. Natural historic processes of wetland formation, classification of wetland function, effects of global changes on wetlands, structure and function of wetland ecosystem, dynamics of wetland ecosystem, and so on, will be important in future study.
