- Abstract:

The aim of this research is to study the spatial evolution of landscape pattern in Peibei coal mining area. Complexity of plaques, centrality, proportionality and cluster were selected as indicators of landscape pattern. Based on the ground of fractal theory, four fractal exponents, boundary dimension, radius dimension, information dimension and lacunarity dimension, had been explored at regional and mining-site scales by using SPOT-4/5 images in 2000, 2004, 2008 and 2012. The results show that:(1) the land cover had changed significantly during the period from 2000 to 2012; cultivated land reduced continuously while the water body and construction land expanded constantly; (2) the landscape patches became more regular, with the gradual loss of equilibrium, the increase of centrality of cultivated land resulted in a single-center distribution pattern; meanwhile, the centrality and the proportionality of the water body, construction land and unutilized land decreased in last decades, a multicenter distribution pattern of water body had formed while the unutilized land had maily distributed around the subsidence water areas; in addition, the obvious ring structure of construction land was detected; (3) the plaque complexity is different from the whole region. Year 2008 is a turning-point for the change of spatial distribution of water body, and the homogeneous distribution gradually formed after 2008.
