Switzer(1965) has demonstrated the existence of a random process in the plane with Markov property. Based on Switzer's theorem, the author has developed planar Markov simulation models for pattern simulation which through program MARKOV Ⅱ have been used tentatively to analyze and simulate some geologic examples. Furthermore, Switzer's theorem is extended to the threedimensional space, and a set of spatial simulated patterns have been constructed by program MARKOV Ⅲ.
