通过对小良试验站不同类型、不同林龄的３种人工林群落（群落Ｂ：桉林；群落Ｃ：松桉混交林；群落Ｄ：阔叶混交林）与当地自然次生热带季雨林（乡土林）相比较，从群落结构的角度探讨人工恢复热带森林的可行性．结果表明：从桉林到松桉混交林到阔叶混交林，３种人工林群落的组成结构和空间结构向着复杂性和稳定性方向发展，并逐渐向地带性自然次生林方向演替；群落的相似性研究也表明，阔叶混交林是３种人工林中与乡土林最为相似．因此，对于极度退化的热带丘陵台地区，在一定工程和生物措施基础上，用先锋绿化树种造林成功后，及时用多层多种的阔叶混交林改造原有先锋林，可以加速人工林向地带性植被类型演替．
Through the experiment of three types of plantation communities with different types and ages in Xiaoliang Experimental Station (community B: eucalyptus forest; community C: Eucalyptus and cinnamomum mixed forest; community D: broad-leaved mixed forest) and the natural secondary tropical monsoon forest Native forest) compared to the feasibility of artificial restoration of tropical forests from the perspective of community structure. The results showed that the compositional structure and spatial structure of three kinds of plantations evolved toward the direction of complexity and stability from eucalyptus to pine-eucalyptus mixed forest to broad-leaved mixed forest, and gradually evolved into the direction of zonal natural secondary forest. Similarity studies also show that broad-leaved mixed forest is the three kinds of plantations and the most similar to the native forest. Therefore, on the basis of certain engineering and biological measures, after the success of afforestation with vanguard green tree species and the timely transformation of the original pioneer forest by multi-layer and broad-leaved mixed forest, Zonal vegetation type succession
