利用2010年贵州森林资源连续清查数据资料,采用一元材积表法对贵州省杉木蓄积量进行估算。分析贵州中心产区和一般产区杉木中龄林蓄积量在不同立地因子下的变化规律。结果表明:中心产区或一般产区的杉木单位面积蓄积量在不同立地条件下均有差异,地貌、坡位对杉木蓄积量有显著影响,坡向、坡度对其影响不显著。初步认为在中心产区与一般产区,不同气候类型是引起杉木生长差异的重要因素之一。
利用2010年貴州森林資源連續清查數據資料,採用一元材積錶法對貴州省杉木蓄積量進行估算。分析貴州中心產區和一般產區杉木中齡林蓄積量在不同立地因子下的變化規律。結果錶明:中心產區或一般產區的杉木單位麵積蓄積量在不同立地條件下均有差異,地貌、坡位對杉木蓄積量有顯著影響,坡嚮、坡度對其影響不顯著。初步認為在中心產區與一般產區,不同氣候類型是引起杉木生長差異的重要因素之一。

Based on the forest inventory data of 2010 in Guizhou province,this study aimed to estimate the stand volume of Chinese fir forest of middle age in the central region and ordinary regions with the method of single entry volume table,and analyzed the changing rules of the stand volume under different site fac-tors.There were some differences in per unit area of stock volume between the central region and ordinary regions under different site conditions,and landform and slope positions had significant influence on the stand volume of Chinese fir forest,while the slope direction or slope angle hadn’t.The study showed that the central region and ordinary regions were in different climate types which maybe was the important rea-son leading to differences of growth in Chinese fir forest.
