摘　　要：于2023年在福建省尤溪国有林场,以4种立地质量等级的45年生木荷人工林为研究对象,采用平均木树干解析的方法,分析人工林生长特征及其数量成熟龄。结果表明:4种立地等级的45年生木荷人工林平均单木年平均生长量表现为Ⅰ类>Ⅱ类>Ⅲ类>Ⅳ类,但其峰值出现的年龄则随林地等级的下降而提早。人工林数量成熟龄,Ⅰ、Ⅱ类地大于45 a,Ⅲ、Ⅳ类地则分别约为40 a、35 a。研究结果可为制定不同立地质量等级木荷人工林高效经营措施等提供参考。The average stem analysis method was used to analyze the growth characteristics and quantitative maturity age of the 45 a Schima superba plantations of 4 kinds of site quality grades.Results showed that:the average individual tree mean annual increment of the 45 a S.superba plantations of four site classes was in the order of ClassⅠ>ClassⅡ>ClassⅢ>ClassⅣ,but the peak age was advanced with the decline of the forest class.The quantitative mature age of the planted forest in ClassⅠandⅡland was more than 45 years,while that of ClassⅢandⅣland was about 40 years and 35 years,respectively.The results of the study can provide a theoretical basis for the development of efficient management measures for S.superba plantation according to site grade.
