Box dimension and information dimension based on individual and leaf number were applied to analyze the distribution patterns of Plantato asiatica and P. viriginica in suburbs of Jinhua. The results showed that both the box dimension and the information dimention of P. virginica were obviously higher than those of P. asiatica in the high human-distributed environment. P. asiatica was mostly distributed in the environment with compacted soil. The information dimension on the basis of leaf probability in the boxes showed that the populations of P. virginica and P. asiatica in low density could exploit environmental resources effectively. 展开更多
