摘　　要：选取鲁中山地有代表性的侧柏(Platycladus orientalis(L.)Franco)人工林,调查分析了侧柏各部位生物量差异;采用偏相关分析法,研究了土层厚度、坡度、坡向、海拔、坡位等主要立地因子与侧柏生物量之间的关系;依据偏相关分析结果对鲁中山地侧柏人工林立地类型进行划分。结果表明:坡向和坡位是影响鲁中山地侧柏林生长的显著因素;根据坡向和坡位的不同,侧柏人工林立地类型可划分东向上坡、东向中坡、东向下坡、西向上坡、西向中坡、西向下坡6个类型。Some typical plantations of Platycladus orientalis(L.)Franco in the central mountainous region of Shandong Province were selected to investigate and analyze the difference of biomass in various parts.The relationships between biomass of P.orientalis and different site factors including soil layer thickness,slope gradient,slope direction,altitude,and slope position were studied by partial correlation analysis,according to which the site types were classified.The results showed that slope direction and slope position had significant effects on the growth of P.orientalis.According to the different levels of slope direction and slope position,the plantations of P.orientalis in the central mountainous region of Shandong Province were classified into six site types involving eastward-uphill slope,eastward-middle slope,eastward-downhill slope,westward-uphill slope,westward-middle slope,and westward-downhill slope.
