Studying spatial distribution of plant population with different crown breath can give the information for the mechanism of population distribution. Fractal geometry of crown is considered to be a very useful tool for dealing with the distribution of crown. In this paper,the fractal dimension of different species crown in the Shouning and Pingnan Pinus taiwanensis forests were calculated and compared. The results indicated that the fractal dimension of Pinus taiwanensis population in Shouning was larger than that of population in Pingnan. The fractal dimensions of different species in Pingnan were larger,which showed that the competition of variable populations was not intense. On the contrary,the smaller fractal dimension of Pinus taiwanensis population in Pingnan showed that the competition was very intense.
