Simulation of Landscape Pattern of Old Growth Forests of Korean

Landscape can bc considered a spatially heterogeneous area. and spatial pattern refers 10 the arrangement of strucrural heterogeneity of environments. resource and biological systems in space (Forman et al 1986. Turner 1987. I9S9. Risser 1987. Turner et al 1991). Turner ( 1987. 1989) considered that spatial pattern has important consequences regarding the effective dispersal of organisms among landscape elements and the spread of disturbance across the landscape. In landscape ecology. spatial patrerns \\ere caused hy different natural proccsses and interactions under di flixtn scales. and were distributed regularity in landscape mosaic. Therefor. it is one of the nG1 questions in landscape ecokgical studiestI,i et al 1988. Wiens 1988. Turner 19891. There clists ;I vertical and borizonral varihtions of vegetationtc.g..
