摘要：以不同立地条件的69块山苍子人工林为研究对象,通过调查其生长及经济性状,利用主成分分析和数量化理论Ⅰ分析立地因子与山苍子树高之间的关系,评价山苍子立地生产潜力。结果表明,坡度、地貌、土壤厚度、土壤质地、坡向5个主导因子与山苍子树高数量化拟合复相关系数为0.47,达到了极显著水平(P<0.01)。采用坡度、地貌和土壤厚度3个因子组合,可将立地类型划分为20个;对每个立地类型立地质量评价分析得出,研究区有75%的样地立地质量在中等以上。山苍子栽培在坡度26°~45°、丘陵和平原以及中厚土层(>40 cm)立地条件下生长和产量较好。
In order to systematically evaluate the potential production of Litsea cubeba,the relationship between site factors and average tree height of 69 plots in L.cubeba plantation was analyzed by investigating the growth and economic characteristics,and using the principal component analysis and theory of quantification Ⅰ.The results showed that the quantized fitting complex correlation coefficient of the five leading factors of slope,landform,soil thickness,soil texture and exposure with tree height was 0.47,reaching an extremely significant level(P<0.01).The site type could be divided into 20 categories by using combination of slope,topography and soil thickness.Meanwhile,the site quality evaluation analysis showed that 75% of the sample sites in the study area were in medium or higher quality level.In conclusion,the growth and yield of L.cubeba were better in the slope of 26°~45°,hills and plains,and medium-thick soil layers(>40 cm).
