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.
