本文以植物群落调查样地资料为基础 ,从不同的类型、层次的丰富度、均匀度和多样性指标对山东胶南沿海地区的植物群落多样性进行了分析 ,分析表明 :本地区的植物生长型与群落多样性指数的关系表现为“乔木与灌木的丰富度指数相近且明显低于草本层 ,群落间变动幅度较小 ,乔木层则变动幅度很大 ;多样性指数多表现出草本层 >乔木层 >灌木层 ;群落物种多样性对小气候有一定影响 ,但与其区域环境有关。
Based on the data collected from plant community survey, the diversity of plant communities in Jiaonan coastal area of Shandong Province was analyzed from different types and levels of richness, evenness and diversity index. The results showed that the plant growth pattern The relationship between diversity index and community diversity was as follows: "The index of richness of trees and shrubs was similar and significantly lower than that of herbaceous plants, but the change of community was small and the variation of tree layers was very large. Stratum> shrub layer. Species diversity of community has some influence on microclimate, but it is related to its regional environment.
