【摘要】 以成都沙河上游、中游、下游3段流域8块滨水绿地为例,采用样方调查方法,分析了植物种类构成、植物多样性指数和均匀度指数,以期为城市滨水绿地植物景观营造提供参考。结果表明:在32个样方中共有植物55科87属110种,其中乔木50种,灌木36种,草本24种;植物多样性Shannon-wiener指数、Simpson指数植物、丰富度Margalef指数和均匀度Pielou指数均表现为乔木层>灌木层>草本层,其中多样性指数为下游段>上游段>中游段;丰富度Margalef指数和均匀度Pielou指数以上游段乔木层最大,而中游段草本层最小,灌木层的物种丰富度和均匀性在3段绿地中差异不明显。更多还原

【Abstract】 Taking 8 waterfront green spaces in upstream,midstream and downstream sections of Shahe in Chengdu,the species composition,species diversity index and evenness index of plant community were analyzed in order to provide reference in plant landscape construction in city waterfront park.The results showed that there were 110 kinds of plants in 32 type places including 50 kinds of arbor,36 kinds of shrub,24 kinds of herbaceous,the four indexes as Shannon-Wiener index,Simpson index,Margalef index and the Pielou index appeared as arbor layer>shrub layer>herb layer and downstream>upstream>midstream in different section.The maximum Margalef index and Pielou index were appeared in upstream arbor layer while the minimum were in midstream herb layer.There were no obvious difference in species richness and evenness of the shrub layer in three sections of Shahe.更多还原
