摘　　要：本文以贵州荔波水族地区森林林下层植被为研究对象,重点研究林下灌草层植物多样性与环境因子之间的相关性。选用Patrick指数,Shannon-wiener指数和Pielou指数,通过相关性分析,多元逐步回归及通径分析方法,研究影响森林群落多样性的影响因子。结果表明:地形因子对森林灌草层植物的Patrick指数有显著影响,干扰因子对森林灌草层植物的Shannon-wiener指数、Pielou指数有显著影响。In this paper,the correlation between plant diversity and environmental factors in the undergrowth shrub and herb around Shui area of Libo in Guizhou Province was mainly studied.Three biodiversity indexes of Patrick diversity index,Shannon-wiener diversity index and Pielou diversity index were selected to study the effect of influencing factors of forest community diversity by means of correlation analysis,multiple stepwise regression and path analysis.The results showed that the topographic factors had significant influence on the Patrick diversity index,and the anthropogenic factors had significant influence on the Shannon-wiener diversity index and Pielou diversity index.
