摘要

<正>通过对湖北鄂州长江外滩草本植物群落进行调查,研究滩地造林和林下间作对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及生物量变化的影响。在此次观察期内的研究结果表明:(1)滩地造林使草本植物物种增加16种,群落类型增加7种;(2)滩地造林使原优势种芦苇(Phragmitesaus tralis)和荻(Miscanthussacchariftorus)的重要值和生物量都有所下降;(3)滩地造林明显增加草本植物群落的Shannon Wiener指数H’和丰富度R,使Pielou均匀度指数J有一定程度的提高,但不影响Simpson指数D;(4)林下间作能提高草本植物群落的物种多样性。

Abstract

The effects of afforestation and intercropping on herb species composition,type of herb community,species diversity,change of important value(IV) and biomass of dominant species were studied through investigating herb vegetation on beach land of the Yangtzi River along Ezhou,HuBei province.The results showed:(1)16 Herb species,types of herb community increased because of tree plantation on beach land.(2)Afforestation on beach land leaded to IV and biomass of dominant species (Phragmites australis and Miscanthus sacchariftorus) decreased in the herb community.(3)Plantation increased significantly Shanno-Wiener index H' and species richness R of herb community,increased eveness index J to some extent,but did not impose effect on Simpson index D.(4)Intercropping brought positive effect on herb community species diversity.
