Abstract: Wetland is one of ecosystems with important environmental functions and habitats for various biota on the earth. It is composed of hydrology, biogeochemical cycling and adaptation and improvement of biota for it. The interaction among those factors creates the entire function of wetlands. The role of wetlands in global environment is mainly found in the two aspects amongst health of wetlands themselves and function of wetlands in global environmental change. A wetland without being disturbed by unusual natural and human activities is in health statue since its diverse species, complex structure, function integration and stability of resisting disturbance. If disturbance is beyond the repairing ability of wetland environment, the health of wetland will be deteriorated, function of wetlands will be degenerated, consequently, will affect local and global environment. Wetland environmental change is sensitive to the responses of global environmental change and effect of global change to the wetland environment, especially human community activities on wetland. Global environment will inevitably affect wetland ecosystem and local environment, conversely, wetland ecosystem and local environment problem probably turn into global environment prblem.
