摘　　要：对林分的生长过程、形成原因和功能特征进行了分析 ,建立了马尾松低质低效林综合等级的判别函数 ,将林分划分为 4种类型 :极低质低效型、生长潜力型、低质型、综合低质低效型 .对林分立地因子的逐步回归分析表明 ,在不同的区域范围内 ,影响马尾松生长的主导立地因子有所不同 ,但海拔、土层厚度和坡度是影响马尾松生长排在前三位的 3个主要因子 ,它们的组合可以构成不同的立地条件类型 .根据对各等级的林分生长过程及其立地特征的分析 ,提出了划分马尾松低质低效林的技术参数标准 .Analysis on the growth procedure,the courses that results the stand development and the function features of the stands, we established the judge function of incorporate grades of the low quality and low benef it Masson Pine secondary stands and divided it into four types: the extreme low quality and low benefit type, the potential type, the low quality type and the incorporate low quality and low benefit type. Gradual regression analyses on the site factors shows that in different areas the main site factor that effects the growth is different. The altitude above sea level, the lopes and the soil deep are still the former three main factors, the combination of them can constitute various site types. Based on the analysis of the stands growth procedure and the site features, we provided the parameter criterion used to sort the low quality and low benefit Masson Pine secondary stand.
