The 9th International Conference on Energy, Resources, Environment and Sustainable Development (ERESD 2022)

A common environmental problem exists in coal resource-based cities in the eastern Huanghuai region of my country. Due to the high underground water level, the surface will sink and accumulate water after the mining of underground mineral resources, resulting in the formation of a large number of coal-mining subsidence wetlands. For a long time, coal-mining subsidence wetlands have led to poor ecological environment in the subsidence area, which has become an important restrictive factor affecting the natural ecological environment, economic development and social stability of the region. In view of this, this study takes the coal-mining subsidence wetland in Xuzhou as the research object, and on the basis of the current situation analysis, explores the space evolvement process, space evolution characteristics and evolution mechanism of the coal-mining subsided wetland, and clarifies the goal of the spatial optimization of the coal-mining subsidence wetland in Xuzhou City. This study proposes targeted optimization strategies for the spatial development of Xuzhou coal-mining subsidence wetlands. In order to provide theoretical guidance for promoting the ecological restoration of coal resource-based cities.
