Coal Ezploitation and Landscape Interaction Changes in Jinggezhuang Mining Area
The evolvement regularity of landscape pattern in mining area is the base of land use structure optimization and security pattern construction. In this paper, the study on mining process and the change characteristics of land types in 30 years in Jinggezhuang in urban-rural fringe shows that the landscape structure in mining area tends to complexity, and the landscape types changes from 4 to 10, and the landscape diversity increases, and the landscape with the greatest change area is still the cultivated land; it is estimated that after the mine closure the regional landscape structure will be optimized further through the comprehensive treatment of regional environment; before the coal mining the patches were irregular in shape, and the landscape diversity index was lower, and the value of landscape ecology was lower; with the exploitation of coal, the patch area decreases, and the density increases, and the shape becomes complex, and the contagion degree of landscape declines, and the quality of the regional ecological landscape declines constantly; after the mine closure and environmental treatment, the landscape shape index and the fractal dimension as well as the area and density of patches will be improved, and the landscape ecological quality will be improves greatly. The analyses indicate adequately that the mining and urbanization have great influences on the landscape pattern in mining area in urban-rural fringe. And the land reclamation is the critical measures on the security pattern in mining area.
