Point pattern analysis of Phyllostachys bissetii ramet population in West China Rainy Area
摘要
Abstract
In this paper, point pattern analysis was conducted to study the spatial distribution of Phyllostachys bissetii ramet population and the spatial association between different age-class P. bissetii ramet populations in West China Rainy Area. The ramet population had a clumped distribution at the scale 0-0.32 m, a regular distribution at the scale 0. 64-4. 48 m. and a random distribution at the scale >4.48 m. Different age-class ramet populations mainly had a random distribution at the scale 0-8.00 m. though a slight difference was observed among different age-classes. The spatial association between age-class Ⅰ and age-classes Ⅱ and Ⅲ at the scale 1.76 -4.16 m and 0. 32-4.16 m approached to or reached to negative, respectively, while the spatial association between age-classes Ⅰ and Ⅳ at the scale 0. 32-3. 04 m was significantly negative. indicating that the spatial negative association between younger and elder ramet populations increased with enlarged age-class difference. The spatial pattern of P. bissetii ramet population and the spatial association between different age-class ramet populations were depended on spatial scale. ramet age, and environmental factors.关键词
