Research advance in mining subsidence wetland landscape pattern and hydrological process

Mining subsidence has a strong disturbance to the ecological environment of resource-based cities which produces a large amount of surface water and forms wetland gradually in the high diving plain of eastern China.The change of landscape pattern and hydrological process is the key content of the research on the formation and evolution of mining subsidence wetlands.It has become an important subject of ecological restoration of mining area and protecting resource-based city ecological security.In this paper, the analyzing method of landscape pattern change of mining subsidence wetland analysis is summarized, including landscape pattern index and landscape dynamic model.In addition, the driving forces of mining landscape pattern change has been summarized systematically.This paper also presents a comprehensive review of hydrologic process, including hydrologic regime, hydrologic cycle, the interaction between hydrological processes and landscape patterns.Finally the research focus on the future development from the perspectives of the coupling mechanism of landscape pattern and hydrological process, comprehensive utilization of ecological service function and optimization for regional landscape pattern.
