摘　　要：柞树红松林、鱼鳞云杉红松林、云冷杉红松林、椴树红松林、枫桦红松林和春榆、水曲柳红松林是小兴安岭南坡红松天然林中常见的６个立地类型。不同立地类型红松优势树高、胸径和年龄三者之间关系分析的结果表明年龄在决定红松优势树高上的意义不大．而优势树高与胸径的相关性密切．符合Ｒｉｃｈａｒｄｓ方程。采用优势树在一定胸径（４０ｃｍ）时的高度值表达立地指数。红松林６个立３也的立地质量差异明显，平均立地指数相差最大可达７ｍ。并讨论了这种新评价方法的理论基础、精度及其在天然复层异龄混交林经营实践中的意义。Six site types of Korean pine(Pinus Koraiensis)forest. Picea jezoensis/Korean pine forest,Picea Koraiensis-Abies nephrolepis/Korean pine forest. Quercus mongolica/Korean pine forest,Tilia amurensis/Korean pine forest.Betula costat a/Korean pine forest and Ulmus propinqua-Fraxinus mandshurica/Korean pine forest,are easily found on the south slope in Xiaoxing'an Mountains.By analyzing the relationships among height.diameter and age of dominant trees of Korean pine in each site type.the results showed that height at a particular age in uneven-aged stands of Korean pine forest often has little biological significance,while the correlativity of dominant height and diameter closely accords with Richards equation.A new method for estimating site quality using height and diameter of dominant trees independent of tree age was examined.Polymorphic site index curves for Korean pine were presented with a reference diameter of 40 cm.The estimated potential productivity was significantely different between six site types、maximum difference of average site index in six site types above can reach 7 m.The theoretical basis,estimation accuracy and significances of the estimation method in managing mixed、uneven aged.natural stands were also discussed.
