摘　　要：对福建省内的福建柏人工林进行立地类型划分和立地质量评价与分级,筛选出较适宜福建柏造林的立地条件,以期为该地区福建柏人工林的经营和管理提供科学依据。在福建省内6个地区的福建柏人工林设置了104块标准样地并调查这些样地的立地因子和林分生长状况,应用数量化理论Ⅰ,筛选出主导因子来划分立地类型,构建数量化预测方程,进而确定立地质量等级并进行数量化评价。结果表明,海拔、土层厚度、坡度、坡位、土壤类型、腐殖质层厚度以及坡向7个环境因子与福建柏树高模型数量化拟合复相关系数为0.7451,模型的F检验达到极显著水平(P<0.01);海拔、土层厚度、坡位是影响福建柏林分生长的主导因子,根据这3个主导因子可划分出25个立地类型;从立地质量划分结果来看,福建柏立地质量优良水平的标准地占80%。福建柏最适宜在中低海拔、较厚的土层和腐殖质层、中坡位、坡度较缓以及阴坡、半阴坡或半阳坡的环境中生长,大部分林分立地质量良好,数量化理论方法可应用于评价立地质量和预测福建柏人工林生长趋势。The site type classification and site quality evaluation were carried out on Fokienia hodginsii plantations in different regions of Fujian Province,and the more suitable growth environment indices were determined to provide a scientific basis for the improvement of production potential.A total of 104 standard plots were set up in F.hodginsii plantations in 6 regions of the province.The site factors and stand growth status of these plots were investigated.By applying the theory of quantification I,the dominant factors were screened out to divide the site type,and then the quantitative prediction equation was constructed and the site quality grade was determined,and the site quality was quantitatively evaluated.The results showed that the 7 environmental factors,including altitude,soil layer thickness,slope,slope position,soil type,humus layer thickness and slope aspect had a complex correlation coefficient of 0.7451 for the quantitative fitting of F.hodginsii height model,and the F test of the model reached a very significant level(P<0.01).Altitude,soil thickness and slope position were the dominant factors affecting the growth of F.hodginsii stand.According to these three dominant factors,25 site types were divided.According to the site quality score of each standard site,the site quality of all standard sites was divided into three grades:excellent,good and poor.From the results of site quality division,the standard land with good site quality of F.hodginsii accounted for 80%.F.hodginsii is most suitable to grow in the sites with the characteristics of middle and low altitude,thick soil layer and humus layer,middle slope position,gentle slope,shady slope,semi-shady slope or semi-sunny slope.Most sites of F.hodginsii in Fujian Province have good quality.The quantitative theory method can be applied to evaluate the site quality and predict the growth trend of F.hodginsii plantation.
