解釋
東綿馬-
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 ）縉雲黃芩各種群空間分佈格局基本呈聚集分佈，其中7個種群的分佈格局類型是聚集分佈，其聚集強度較高，另有一個種群為隨機分佈；其種群的離散分佈擬合結果也嚴格符合一定的數學模式，其中負二項分佈、 poisson分佈分別是該物種種群空間分佈的理論分佈模式，其中6個種群擬合出的結果是負二項分佈，種群i和種群m擬合出的結果是poisson分佈。 -
