| Abstract: | 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. |
