摘要
湿地生物地球化学是湿地生态系统生态过程的核心研究内容。为了系统认识和了解这一核心内容的研究现状和发展趋势,通过对大量的文献和实践研究成果的分析,阐述了湿地生物地球化学的内涵、研究意义、主要研究内容和研究方法;阐明了湿地生物地球化学过程与气温、水文、植被、土壤、生物等环境要素的关系;论述了湿地生态系统对相邻生态系统的作用与影响;分析了湿地系统温室气体排放特征、影响因素及其区域响应。湿地生物地球化学信息的提取与环境变化的关系研究将成为湿地环境研究的热点领域;湿地生物地球化学过程模型的建立,以及模型模拟的时空尺度转换,碳、氮、硫、磷、等营养物质的生物地球化学过程的研究将成为湿地生态过程的研究核心内容。湿地生物地球化学将成为湿地环境功能和服务功能的评价、湿地系统健康与稳定的诊断和退化湿地系统生态修复的重要基础理论。
Wetland biogeochemistry is the core of wetland ecosystem ecology process. In order to know and understand the research actuality and the development tendency systemically, based on the analysis of the massive literature and the research achievement in practice, biogeochemistry connotation, the research significance, the main research content and the research technique were expatiated in wetland; the connection between wetland biogeochemistry process and environment factor, such as temperature, hydrology, vegetation, soil, biology and so on, was expounded; the function and influence of the wetland ecosystem on neighboring ecosystem was elaborated ; and the emission characteristic, influence factor and region response of greenhouse gases were analyzed in wetland ecosystem. It was given that the research of the connection between the gain of biogeochemistry information and environment would become the hotspot domain on research of wetland environment. The establishment of wetland biogeochemistry process model, as well as the simulation of spatial and temporal transformation, the research of the biogeochemistry process of carbon, nitrogen, sulfur, phosphorus and other nutrition, these would be the core content of research of wetland ecosystem process. Wetland biogeochemistry would become the critical basic theory of the assessment about environmental and service functions of wetlands, the estimation of health and stability in wetland system, and the ecological restoration of the degenerated wetland system.
