In this study,15 plots of artificial saplings of Chinese fir were set as the research object in the Jiangle state-owned forest farm.Comparative analysises the outcomes of calculating the spatial structure indexes based on Voronoi diagram and the outcomes of traditional algorithms which the number of the nearest neighbor trees is 4.The result shows:the outcomes have agreement between the two when calculating neighborhood comparison,but the outcomes exist remarkably difference when calculating neighborhood pattern.It indicates that Voronoi diagram is flexible in detesmining forest spatial structural units,and the spatial structural units that are closer to the actual forest fraction distribution.Compared with traditional methods,Voronoi diagram can accurately describe the forest spatial distribution pattern and neighborhood comparison.
