Abstract

It is very important to study the application of fractal theory to further explore the spatial structure of herb populations，which applied the significance of fractal theory in the spatial structure of herbaceous plant populations. Fractal characteristics of two herb populations，Carex kobomugi and Parapholis incurve，on Taohua Island of Zhoushan City were studied using the contiguous grid quadrate sampling method from pattern research and the box-counting and information dimensions from fractal theory. Adjacent grid method to take four random quadrats for quadrat area 1 m1 m in transects C. kobomugi and P. incurva populations. Results showed that fractal dimensions could describe the distribution pattern of the populations with the box-counting dimension ranging between 1.454 2 and 1.745 6 for P. incurva and between 1.318 1 and 1.614 1 for C. kobomugi. Both populations had means greater than 1.500 0，and both had strong ability to occupy the space with P. incurva being stronger than C. kobomugi. The information dimension for populations of C. kobomugi ranged from 1.027 0 to 1.263 4 and of P. incurva from 1.022 7 to 1.381 2 with the mean of P. incurva populations greater than C. kobomugi. Also，the cluster index was higher. Thus，P. incurva population space had a more complex pattern but the difference was not significant. It is great significant to study the application of fractal theory for further exploring the spatial structure of the herb populations.［Ch，3 fig. 2 tab. 14 ref.］
