Title: Geostatistical analysis on the spatial pattern of Pinus tabulaeformis population at different habitats in the Lingkong Mountain
Abstract: In order to reveal the distribution pattern and spatial correlation of Pinus tabulaeformis population,this research used geostatistical theory and methods to examine the distribution pattern and spatial correlation of P.tabulaeformis population in different habitats of the Lingkong Mountain.The results showed that the semivariograms well fitted the exponential model for P.tabulaeformis populations at the mountain ridge,and the spherical model for those in slow slopes and valley areas.All three populations showed aggregated pattern.The spatial heterogeneity of the habitats of ridge,slow slope and valley was mostly due to the spatial autocorrelation in the ranges of 11.16 m,9.99 m and 4.74 m,respectively.The populations at the ridges and gentle slopes showed greater sill values and determinant coefficient but lower fractal dimension than the pines in valleys,indicating that the first two habitats are characterized by higher degree of spatial heterogeneity and more significant spatial patterns,which is not found in the valley populations.Therefore the variations in the spatial distribution patterns of P.tabulaeformis populations is likely resulted from both the intrinsic biological characteristics and the environmental factors.
