摘  要:
首次将连续型Weibull 分布用于珍稀濒危植物长苞铁杉种群空间分布格局的研究,取得理想效果,长苞铁杉种群分布符合Weibull 分布。并根据Weibull 分布建立了长苞铁杉种群最适抽样式,为长苞铁杉种群抽样技术和取样数量确定提供了理论依据。

摘  要:
The Weibull model of spatial distribution pattern was used to simulate spatial distribution pattern of the endangered and rare plant tsuga longibracteata for the first time. The results showed that the spatial distribution pattern of the endangered and rare plant tsuga longibracteata was conformed to Weibull model in population. According to the parameters of Weibull model, the theoretical sampling model of forest survey was established under different population densities and allowing errors, which would provide basic theory for deciding sampling technique and sampling numbers to tsuga longibracteata population.
