Abstract
The spatial pattern of landscape patches in forest area has been becoming clearer to have much effect on habitat distribution, thus landscape analysis is needed for conservation of biodiversity. Recently, abandoned private plantation forests have been ranging widely, and biodiversity loss in the forest landscape derived from enlarging unsuitable spatial pattern for habitats in addition to decline in quality within patches has been apprehended. This paper aimed at showing effects of the spatial pattern of plantation landscape structured through forest management on biodiversity. We simulated the spatial pattern structuring based on scenarios of 3 different thinning plans. Then we considered effectiveness of each spatial pattern changes structured based on scenarios in chronological order on biodiversity, measuring shape, density, nearest neighbor distance and splitting index of forest stand patches which were different manage ranks. As a result, both forest managements according to 2 actual thinning policies were seemed to be effective on conservation of biodiversity, while we could not show more effective management between them.
