以邵阳市资江上、中、下游区域10块城市滨水绿地为研究对象，采用样方调查方法，调查分析滨水绿地植物种类、植物丰富度、植物均匀度和植物多样性。结果表明：丰富度指数、均匀度指数、植物多样性指数均表现为乔木层＞地被层＞灌木层，3个区域滨水绿地均匀度差异并不明显，但乔木的均匀度、丰富度均高于灌木层和地被层，丰富度指数上游区域＞下游区域＞中游区域，多样性指数上游区域最大，下游区域最小。%studying on10 city waterfront greenbelt along the Shaoyang Zijiang River ,the authors investigated and analyzed the plant species,richness,evenness index of the waterfront greenbelt and species diversity index by using the quadrat samplings .The results indicated:the plant richness ,evenness and diversity index of tree layer >that of ground Layer >that of brush layer ,and there was no significant difference in the evenness among three regional waterfront green space , but the evenness , richness of trees were higher than those of shrubs and ground cover.The richness index of upstream region >that of downstream region >that of the middle rea-ches,and the diversity index of the upstream region was maximum while that of the downstream region was minimum .
