星斗山自然保护区广泛分布着常绿阔叶林和常绿落叶阔叶混交林。他们生长繁茂,都是经过破坏后自然恢复起来的天然次生林。本文选择了钩栲林、水青冈、枫香、多脉青冈林为代表,研究了它们的种群结构状况,并探讨了其演替发展的前景。研究结果表明,这两种类型林分的种群结构都很复杂,组成林分的乔木树种分别为28种和29种,但前者常绿成分占88. 57%,后者常绿与落叶成分几乎各占一半。并且在海拔1000M 以下,以钩栲为主的常绿阔叶林是稳定的,而在1000～1500M 的范围里,只能形成常绿落叶阔叶混交林。
Xingdoushan nature reserve widely distributed evergreen broad-leaved forest and evergreen deciduous broad-leaved mixed forest. They flourish and are all natural secondary forests that have naturally recovered after their destruction. In this paper, Hooklin, Fagus, Liquidambar formosum, Cyclobalanopsis glauca were chosen as the representative, their population structure was studied, and the prospect of their succession development was discussed. The results showed that the population structure of these two types of stands was very complicated. The arborous species comprised 28 species and 29 species, but the former accounted for 88.57% of the evergreen, while the latter had almost the composition of evergreen and deciduous Half and half. And in the elevation below 1000M, the hook-based evergreen broad-leaved forest is stable, and in the range of 1000 ~ 1500M, only the formation of evergreen and deciduous broad-leaved mixed forest.
