Abstract

The patchiness of local environments within a habitat is assumed to be a primary factor affecting the spatial patterns of plants, and a randomization procedure is developed for testing the null hypothesis that only spatial association with patches determined the spatial patterns of plants. Chloranthus japonicus (Chloranthaceae) is an herbaceous perennial and a member of the genus Chloranthus in the family Chloranthaceae. The spatial pattern of C. japonicus was analyzed according to several patchiness indices, population uniformity or aggregation under different sizes of plots by dispersion indices, and spatial autocorrelation. Population densities (D) varied from 0.356 to 2.270, with a mean of 1.527. The values of dispersion indices ( at Mt. Ahop were lower than 1 at six plots ($2m{\times}2m$, $2m{\times}4m$, $4m{\times}4m$, $4m{\times}8m$, $8m{\times}8m$, and $8m{\times}16m$), but the two large plots ($16m{\times}16m$ and $16m{\times}32m$) were higher than 1. Thus, the aggregation indices ( were negative at Mt. Ahop, which indicates a uniform distribution. The two large plots ($16m{\times}16m$ and $16m{\times}32m$) had positive CIs. However, the values were not large (0.009 for the $16m{\times}16m$ plot and 0.038 for the $16m{\times}32m$ plot). The mean crowding ($M^{\ast}$) and patchiness index (PAI) showed positive values for all plots.

지역 미세 환경의 패치는 식물의 공간적 분포에 일차적 요인이다. 식물의 공간적 양상을 결정한다는 귀무가설을 임의화 과정을 통해 검증하였다. 홀아비꽃대는 초본으로 홀아비꽃대과(Chloranthaceae) 홀아비꽃대속(Chloranthus)에 속한다. 홀아비꽃대의 공간적 양상을 여러 패치 지표로 분석하였고, 분산 지수에 따른 플롯 크기별 운집 분포, 균일분포, 공간적 상관관계를 분석하였다. 홀아비꽃대의 집단 밀도(D)는 0.356에서 2.270으로 평균은 1.527이었다. 아홉산 홀아비꽃대의 분산지표(C)는 작은 플롯($2m{\times}2m$, $2m{\times}4m$, $4m{\times}4m$, $4m{\times}8m$, $8m{\times}8m$, and $8m{\times}16m$)은 1보다 작았으며 큰 플롯($16m{\times}16m$ and $16m{\times}32m$)은 1보다 상회하였다. 따라서 홀아비꽃대의 운집지표(CI)는 작은 플롯에서 음의 값으로 균일한 분포를 이룬다. 큰 플롯의 운집지표는 양의 값으로 나타났으나 그 값은 높지 않았다. 평균 클라운딩($M^{\ast}$)과 패치지수(PAI)는 모든 플롯에서 양의 값을 보였다.
