重庆南温泉公园植物群落结构及物种多样性研究

Studies on Structure and Species Diversity of Plant Communities in Chongqing South Hot-spritay Park

调查了重庆南温泉公园植物群落的物种组成、群落结构及物种多样性,分析了植物群落的结构特点。南温泉公园物种多样性中,乔木层的Simpson指数非常高,其均匀度指数为3.4173,表明了群落物种的集中程度高,优势种突出。灌木层的Simpson指数相对较低。乔木层和灌木层的Shannon-Weiner指数和均匀度指数相差较大。

This paper based on the study of plant communities through the species composition, the structure and diversity communities of the investigation on Chongqing South Hot-sprtay Park .In South hot-spring Park species diversity, the arbor layer of Simpson index was very high, reached a basically, the index for the uniformity of 3.417 3, a community that the concentration of the species, the dominant species prominent, more species to 1-2.Simpson index of the shrub layer on the relatively low.Arbor and shrub layer of the Shannon-Weiner index and evenness index J were difference.
