摘　　要：毛竹林下草本层是森林生态系统的重要组成部分,对维持生态多样性、促进养分循环和保持水土等具有关键作用。研究通过野外样地试验,探讨龙栖山毛竹林下草本植物群落的组成和多样性特征及其影响因素,以期为亚热带森林生态系统的保护与管理提供理论支持。研究结果表明,龙栖山毛竹林下草本植物群落具有良好的物种多样性,淡竹叶相对丰度、相对生物量较高,为优势种;群落的密度、平均盖度存在显著空间差异;群落的多样性特征与土壤含水率、容重、有机质含量等环境因子存在显著相关性。未来,研究应结合长期监测数据揭示土壤因素与植物多样性之间的复杂关系。The herbaceous layer under Phyllostachys edulis forest plays a key role in maintaining ecological diversity,promoting nutrient cycling,and soil conservation.This study investigates the composition and diversity characteristics of the herbaceous plant community under the Phyllostachys edulis forest in Longqi Mountain to provide theoretical support for the protection and management of subtropical forest ecosystems.The results showed that the herbaceous plant community in Longqi Mountain Moso bamboo forest has good species diversity,with Lophatherum gracile having a high relative abundance and relative biomass,making it the dominant species.There were significant spatial differences in the community′s density and coverage.The diversity of the community is significantly correlated with environmental factors such as soil moisture content,bulk density,and organic matter content.Future research should combine long-term monitoring data to reveal the complex relationship between soil factors and plant diversity.
