A new modified random clusters method for the simulation of landscape the m
atic spatial patterns is presented. It produces more realistic and general
results than landscape models that have been commonly used to date in the f
ield of landscape ecology. Simulated patterns are said to be realistic, apa
rt from their patchy and irregular appearance, because the values of the sp
atial indices as a function of habitat abundance measured in real landscape
patterns (number of patches, edge length and patch cohesion index) can be
replicated with the proposed landscape model. It allows a wide range of spa
tial patterns to be obtained, in which fragmentation and habitat abundance
can be systematically and independently varied. Furthermore, a degree of co
ntrol over the irregularity of the shapes of the simulated landscapes can b
e achieved, and it is also possible to simulate patterns with anisotropy. T
he proposed method is easy to implement and requires little computation tim
e, which enhances the practical possibilities of this method in different a
reas of landscape ecology.
