赤水河中段清香木天然群落物种多样性研究
Study on the Diversity of Main Community of Pistacia weinmanni f olia in Natural Forest in Chishui River
摘要
Abstract
Chishui River is rich of biodiversity in the region ,in order to accurately and reliably grasp the middle of the Chishui River community biodiversity information of Pistacia weinmanni f olia ,along the Chishui River in the domain of altitude (445~933 m) highly ,taking seven distribution typical of natural Pistacia weinman‐ni f olia plots of 20 m × 20 m ,using contiguous grid survey method ,the dominance of species ,species richness degree ,species diversity index and evenness were analyzed .The results showed that 1)The main advantage of the shrub layer was Pistacia weinmannifolia ,followed by the Osteomeles schwerinae ,species richness was small ,56 species were investigated including 42 woody plants and only 14 herbaceous layers .2)Shrub layer , species richness and species diversity index were significantly greater than the herbaceous layer ;3)Shrub layer Sirnpson average index was 0 .827 0 ,Shannon‐Wiener index was 2 .054 8 ,average evenness was 0 .793 9 , 0 .899 7 ,which indicated a low diversity index .关键词
