%X 以大洪山鸳鸯溪河漫滩为实验地点,采用样线法和随机样方调查法,开展不同水位点的河漫滩植物多样性的调查研究.研究结果表明:鸳鸯溪河岸带植物共有29科44属47种,其中草本植物30种,灌木6种,藤本植物5种,灌木或小乔木3种,乔木3种;离水越近的样地更多的物种是多年生草本,远离水的样地更多分布的物种是木本植物,1年生物种在2个样地中的分布无统计学意义上显著差异;鸳鸯溪河岸道分布有群丛类型16个,湿生类有2个,两栖耐受类有3个,陆生类有4个,灌木类有4个,乔木类有2个;2个样地多样性指数存在统计学意义上显著差异,离水越近的样地的物种数显著高于远离水的样地物种数.<br>To clarify how plant community in the riparian zone respond to the water level changes in the environment,the experiment was adopted the line transect method and random sampling investigation method to carry out the plant diversity research under different water levels with the riparian zone in Yuanyang Stream in Dahong Mountain as research sites.The study revealed that the plants in riparian zone belonged to a total of 44 genera,29 families and 47 species,including 30 herb plants,6 shrubs,5 shrubs or small trees and 3 trees.Most of species at the site closed to the riverside were perennial herbs,while main species distributing in the site far away from the riverside were woody plants.Otherswise,annual species had no significant difference at two sites.At the same time,the result showed that there were 16 plant association types distributing in the riparian zone of Yuanyang Stream,including 2 hygrophilous types,3 amphibious tolerance types,4 land plant types,4 bush types and 2 tree types.Finally,diversity index at two sites had significant difference,and the number of species at the site near the stream was significantly more than those at the site far away from the stream
