This paper analyzed the landscape pattern changes and the ecological effects before and after the governance in Zhonghu coal mining subsidence area in Huaibei based on the interpretation of remote sensing images in 2005, 2014 and 2018. The results showed that in this area before the governance, cultivated land fragmented severely, the landscape advantage was the greatest but continued to weaken, water tended to gather in subsidence area, while after the governance, the landscape matrix changed from cultivated land to waters. The area of woodland and grassland significantly enlarged and the landscape advantage increased, the degree of water aggregation in artificial lakes was high. The regional landscape fragmentation weakened, and the degree of fragmentation in the central area was lower than that in〖JP〗 the northwest. Besides, the landscape spread degree was stable, the landscape diversity increased, the positive edge effect strengthened, and the ecological environment quality improved. In the governance of resource exhausted mining areas, it was necessary to rationally optimize the water land landscape pattern, improve the ecosystem structure, and reduce the landscape fragmentation in urban development. |
