针对常绿阔叶林树种组成结构复杂,种类繁多的特点,对林分树种组成结构、数量结构和产量结构的动态变化规律及其相互关系进行了10年的研究,结果表明:(1)林分树种划分为重要速生树种、重要慢生树种和次要树种3类;(2)3类树种组成结构和株数比例(N%)随年龄(A)增加呈规律性变化。重要速生树种株数比例与年龄呈线性关系,组成和数量结构较稳定;重要慢生树种株数比例与年龄呈双曲线关系,相关密切;次要树种株数比例与年龄呈二次抛物线关系,相关密切;(3)3类树种材积比例(V%)随年龄的变化规律与株数比例的变化规律相类似,但相比之下,重要速生树种的材积比例的变化尤为重要,而另2类树种的株数比例的变化更重要些。(4)3类树种材积比例与株数比例之间均存在线性相关。其中重要速生树种在林分中生产力较高。
In view of the complicated structure and wide variety of tree species composition of evergreen broad-leaved forest, the dynamic changes of compositional structure, quantity structure and yield structure of tree species were studied for 10 years. The results showed that: (1) The species of tree species are divided into three categories: important fast-growing tree species, important slow-growing tree species and minor tree species. (2) The compositional structure and the number of tree species (N%) of the three tree species change regularly with age (A). The proportion of important fast-growing tree species has a linear relationship with age, and its composition and quantity structure are stable. The proportion of important slow-growing tree species has a hyperbolic relationship with age, which is closely related to each other. The proportion of secondary tree species has a quadratic parabola relationship with age, (3) The variation of volume percentage (V%) of three tree species with age is similar to that of the number of trees, but in comparison, the change of volume ratio of important fast-growing tree species is especially important. Changes in the proportion of more important. (4) There is a linear correlation between the proportion of three tree species volume and the number of trees. Among them, the important fast-growing tree species have higher productivity in the forest.
