  • The competition among those species like s . tsinyunensis , dryopteris erythrosora and veronicastrum stenostachyum etc . , is intense in the communities , which may be one of the reasons why s . tsinyunensis is going to be endangered and with a very restricted distribution . the distribution patterns of the seven populations of s . tsinyunensis are clumped among the eight populations we studied , except population v of random distribution . the spatial pattern of 6 populations of s . tsinyunensis have high consistency with the negative binominal distribution , while another 2 populations , i . e . , i and iii are poisson distributions
    6 )縉云黃芩各種群空間分布格局基本呈聚集分布,其中7個(gè)種群的分布格局類型是聚集分布,其聚集強(qiáng)度較高,另有一個(gè)種群為隨機(jī)分布;其種群的離散分布擬合結(jié)果也嚴(yán)格符合一定的數(shù)學(xué)模式,其中負(fù)二項(xiàng)分布、 poisson分布分別是該物種種群空間分布的理論分布模式,其中6個(gè)種群擬合出的結(jié)果是負(fù)二項(xiàng)分布,種群i和種群m擬合出的結(jié)果是poisson分布。
