基于分形維數(shù)的煤礦區(qū)景觀格局特征——以徐州市沛北礦區(qū)為例
[Abstract]:Taking the SPOT-4/5 images of Peibei mining area in Xuzhou City as data source in 2000, 2004, 2008 and 2012, the complexity of landscape pattern in the study area was analyzed synthetically by using the theory and method of fractal theory, selecting the shape, radius, information and interspace of the four dimensions of landscape pattern in the study area. Concentric, balanced and clustered, the evolution characteristics of landscape pattern were studied from the two scales of mining area and mine field. The results show that: (1) the land use has changed dramatically from 2000 to 2012, a large number of cultivated land has been transformed into water area and construction land, and the water area and construction land have increased significantly. (2) the landscape patch tends to be regular and the complexity decreases; The spatial distribution developed to non-equilibrium, the degree of aggregation increased, and the centrality of cultivated land increased and tended to single center distribution. The concentric, equilibrium and spatial distribution of water area, construction land and unused land tend to be multicentric, and the unused land is concentrated around the collapsed waters. The circle structure of spatial distribution of construction land is obvious. (3) the shape of landscape patch is more complex, 2008 is the turning point of spatial distribution of water area, and then the spatial distribution tends to be uniform.
