Abstract: Background, aim, and scope Coal mining leaded to large land subsidence. Due to the groundwater level in the central and eastern plains of China is shallow, forming water areas in the mining areas and changing the regional ecological environment. The Panxie coalmine area we selected area was the main mining area in Huainan, facing significant change of land use and landscape pattern. This research would have addressed the impact of land use of mining areas on regional landscape patterns, to provide a certain theoretical basis for local social and economic sustainable development. Materials and methods The land use maps of five phase of the study area, covering 1980, 1990, 2000, 2010 and 2015 respectively, were selected to analyze the change of land use by using land transfer matrix. Then the change of landscape patterns was analyzed by calculating formula and significance of landscape index. Results The arable land, construction land and water area were the main land types in the study area, and the transition between the three was the closest. The cultivated land reduced in the region over the past 35 years, mainly converted into construction land and waters. The landscape superiority of the mining area decreased, the landscape diversity increased, resulting in more balance of the regional landscape pattern. Discussion The land use structure of Huainan mining area has undergone great changes in the past 35 years due to social and economic development, coal mining activity and population growth. As long with the continued mining activities, the area of subsided water area is becoming large with increased impact on regional landscape. Conclusions The change of land use mainly reflects in the reduction of arable land area, construction land, and the increase of water area, increased the regional landscape diversity and further reduced the dominance. The regional landscape pattern tended to be more diverse and balanced. Recommendations and perspectives While meeting the needs of social and economic development, the mining area needed to promote practical reclamation plans and comprehensive management plans to make rational use of subsided water bodies to minimize human interference with the environment, such as rational use of subsided water bodies, development of industry, agriculture, and fisheries. At the same time, we have to pay attention to the protection of water resources to keep the balance between their economic and environmental benefits.
