ABSTRACT
Coal mining activities in high groundwater area will cause many damages, such as tie up of land and land subsidence. The coal mining activities will lead to the surface formation of perennial water area, the seasonal water area and water slope. These activities will make the land transform into aquatic-terrestrial complex environment. Due to coal mining activities have enormous influence on the landforms, terrain and many other aspect, and because of the period is short and hydrological conditions, the species and the environment have also changed much, in this long and seasonal water conditions form the new ecological environment[1]. This new environment make the mining subsidence area with high groundwater change the process of carbon source and carbon sinks, and will also change the function of water storage and flood detention. With the development of this new environment making these changes with wetland ecological characteristics. According to the definition of the ramsar convention in 2002, Wetland refers to natural, artificial or temporary marshes,
tures from the direction of different features of perennial water and seasonal water in high groundwater mining subsidence area. We hope this article can coordinate mining area land reclamation work and be able to provide the basis for wetland maintenance in subsidence area.
