Its research orientations include the ecosystem structure of wetlands,their ecological processes,environmental effects,cataloging and dynamic changes in natural endowment,the assessment of the ecological ambience of representative or distinctive wetlands,countermeasures for the protection of biodiversity,the classification system of wetlands,related evolutionary patterns,and biomass productivity.The aim of the center is to accomplish high-level results in basic research and applied research in wetland research so as to serve eco-environmental protection and socio-economic development in a steady and sustained way. The main research tasks of the center is,by uniting all academics engaged in wetland research in the Academy,to host investigative surveys of and application for key R&D topics in the field, organize theoretical probes into the disciolinarv basics,establish China’s own scientific system and databases展开更多

They occur in landscapes that favor the ponding or slow runoff of surface water, discharge of ground water, or both. Wetlands are not only important for maintaining plant and animal diversity, but also for balancing global carbon budget via sequestrating or releasing CO2 from/into atmosphere depending on their management. Therefore, it is imperative to understand how wetlands form and function, then we can better manage, utilize, and protect these unique ecosystems. Hydrie soils,hydrophytic vegetation, and wetland hydrology are the three main parameters of wetlands. These parameters are interrelated with each other which jointly influence the development and functions of wetland ecosystems. The objective of this paper was to report the current understanding of wetlands and provide future research directions. The paper will first focus on aspects of hydrology research in wetlands, and then shift to soil hydrosequence and wetland vegetation to better understand processes, structure, and function of wetlands, and conclude with some possible future research directions.展开更多
