武汉东湖落雁景区南部木本植物多样性研究

摘要

An investigation and statistical analysis was conducted on the tree species composition and diversity index etc., of the green space of the southern part of Luoyan Scenic Spot of East Lake, by using typical sampling method. The results showed that 116 plant species were identified in the green space of the southern part of Luoyan Scenic Spot of East Lake, which belong to 50 families, 86 genera. The Margalef richness index of arbor layer was 0.613 2~2.125 7 and the Margalef richness index of shrub layer was 0~1.321 1. The entire plant community's Shannon-Wienner index was 0.814 2, Simpson index was 0.819 5 and Pielou evenness index was 0.171 2.%采用典型抽样法，对武汉东湖落雁景区南部木本植物的树种组成、多样性指数等进行了调查统计分析。结果表明：东湖落雁景区南部木本植物种类共有116种，隶属于50科86属；乔木层Margalef丰富度指数为0.6132～2.1257，灌木层Margalef物种丰富度指数为0～1.3211；整体植物群落的Shannon-Wienner指数为0.8142，Simpson指数为0.8195，Pielou均匀度指数为0.1712。
