The spatial heterogeneity is determined with the help of mathematical indices. Information index indicate order and disorder in landscape pattern formation. Fractal pattern of landscape indicate spatial heterogeneity. Propagation of disturbances across spatial pattern could also be described by percolation values. A comparison of three indices helps us to visualize the pattern formation across landscapes with probable causes. Two typical landscapes of north-western parts of Orissa, India is taken as sample study. The obtained entropy values, fractal dimensions and percolation pattern indicate complexity in the pattern development due to intense anthropogenic activities rather than natural one. http://pubs.sciepub.com/ajma/2/1/1/ajma-2-1-1.pdf spatial heterogeneityfractal patternpercolation patternanthropogenic activities
