摘　　要：本文以不同树种人工林和无林滩地内草本植物群落调查资料为基础,从草本植物群落物种组成、群落类型、物种多样性、原生优势种的重要值以及物种丰富度、均匀度等方面对望江县长江外滩血防林下草本植物群落多样性进行分析。结果表明:(1)人工血防林造林后草本植物群落类型明显增多,草本植物物种增加了76种;(2)造林明显增加滩地草本植物群落的Shannon-Wiener指数和丰富度,对Pielou均匀度指数有一定影响,但不影响Simpson指数,其中重阳木林和枫香林林下草本植物种类最为丰富。本研究揭示不同林龄滩地造林与草本植物群落物种多样性的内在联系,旨在为促进人工林下草本植物群落物种多样性以及人工林生态系统下物种多样性的保护与持续利用提供最基本的经营管理依据。In this paper,based on the survey data of herbaceous communities in the plantations of different tree species and non-forest marshlands,an analysis was made on the diversity of herbaceous communities in Oncomelania hupensis control and schistosomiasis prevention plantations along the beaches of the Yangtze River within Wangjiang County from such aspects as species composition,community types,species diversity,importance value of indigenous dominant species,species richness and evenness.The results showed:1.The types of herbaceous communities increased significantly after the establishment of Oncomelania hupensis control and schistosomiasis prevention plantations with 76 more herbaceous species added;2.Afforestation significantly increased the Shannon Wiener index and richness of herbaceous communities in the beach and improved the Pielou evenness index to some extent,but did not affect the Simpson index,in which the richness of herbaceous species in plantations of Bischofia polycarpa and Liquidambar formosana was the highest.The study revealed the internal relationship between different-aged marshland plantations and species diversity of herbaceous communities,which could provide basic management reference for promoting species diversity of herbaceous communities in the plantations and conservation and sustainable utilization of species diversity in the plantation ecosystem.
