Fractal Dimension of the Spatial Distribution of Dryobalanops lanceolata in a Tropical Rain Forest, at Lambir, Sarawak

Abstract

We analized the character of distributional pattern of Dryobalanops lanceolata by calculating the correlation dimension. We counted points reflected at the boundary as well as at the corner to correct the lack of points near the boundary. Its cerrelation dimension is about 1,33 with small scale and it has some remarkable decreases and increases in dimension, suggesting the change of the character of the distribution, Comparing the correlation dimension with the box dimension and I-delta index, correlation dimension is sensitive to the scale where the distributional character changes, Therefore the correlation dimension can be a new index that shows the change of the characters of distribution in scale.
