【摘要】There is uncertainty and limited knowledge regarding stand characteristics and soil properties of middle-aged pure forest plantations in the mountainous area of Western Sichuan.Plantation forests are almost exclusively planted as monocultures in the Pengzhou forest farm in the western mountainous area of Sichuan Province.This study aimed to assess the spatial and ecological characteristics of middle-aged Cunninghamia lanceolata (Lamb.) Hook.and Cryptomeria fortunei Hooibr.in the Pengzhou forest farm.The relationships and differences between stand growth characteristics and forest soil composition were assessed on the two forests planted simultaneously within the same area and exposed to the same environmental conditions.Cr.fortunei

grew

sparse,and

slower

than

Cun.lanceolata.Principal component analysis indicated that the soil properties in the Cr.fortunei plantation were better than those in the Cun.lanceolata plantation.Redundancy analysis revealed that the differences in stand structure were affected significantly by the total
