摘要
对北川驴蹄草(Caltha dysosmoides)的种群分布格局进行相关研究分析,旨在为更好的保护和开发利用提供相关数据。以北川竹林沟保护站巡护点(E104°13'20.2″,N32°13'9.5″)为中心设置9个样地,调查北川驴蹄草174丛共计796株。通过等距取样法将其分为20个样方,采用方差/均值比率法分析北川驴蹄草的种群分布格局。结果表明:20个样方中1-a,1-d,2-b,2-c,2-d,2-e,2-f,4-a,5-a,6-a,6-b,7-a,7-b,8-a,9-a为集群分布;1-b,1-c,2-a,2-g,7-c为均匀分布。
Analysis was made of the population distribution pattern of Caltha dysosmoides,aiming to provide data for the protection and exploitation. A survey was conducted arourd patrolling point of Beichuan bamboo ditch protection station( E104°13'20. 2″,N32°13'9. 5″). During the investigation,9 plots were set,and there were 796 plants in 174 groves of Caltha dysosmoidea,which were divided into 20 samples by equidistant sampling method,and with variance/mean ratio method,the population distribution pattern of the Caltha dysosmoidea was analysied. The results showed that the 1-a,1-d,2-b,2-c,2-d,2-e,2-f,4-a,5-a,6-a,6-b,7-a,7-b,8-a,9-a were clump distribution in 20 samples,and the 1-b,1-c,2-a,2-g,7-c were uniformly distributions.
