子午岭次生林区的植被曾经历了人为破坏过程与自然恢复过程。研究结果表明:次生林恢复前该区土壤类似现在的黄绵土;在植被恢复过程中,土壤发育程度逐渐增强,具有一定的腐殖化过程和淋溶过程,土壤向褐色森林型土壤演变;林地被人为开垦破坏后,加速侵蚀迅速发展导致土壤剖面迅速遭到破坏,土壤向黄绵土演变。

The vertical difference of vegetation is one of the important law of vegetation ecology.On the basis of the vertical difference of shrub wood vegetation in flora,growth form,origin,dominant synusia,dynamics and human impacts,three vertical zones of shrub wood vegetation were distinguished in this basin:(1) Zone of subalpine evergreen/diciduous broad leaf bush wood,alt 2000-2600 m;(2) Zone of middle mountain deciduous broadleaf bush wood,alt.1000-2000 m;(3) Zone of low mountain deciduous broadleaf bush...

植被的垂直分异是植被生态学的重要规律之一,根据旬河流域灌丛植被分布的特点,首次提出该流域灌丛垂直带的划分:(1)亚高山凉温性常绿、落叶阔叶典型灌丛带(2000-2600m);(2)中山温性落叶阔叶典型灌丛、杂木灌丛带(1000-2000m);(3)低山暖温性落叶阔叶典型灌丛、草灌丛带(1000-600m)。各带灌丛植被有其各自的区系成分、起源、外貌以及与森林植被的关系等特征。流域灌丛植被垂直分异规律的研究,对流域灌丛植被的保护和森林植被的恢复以及流域的综合开发具有重要意义。

Three artificial forest communities (i.e. community B: eucalyptus forest; community C: pine and eucalyptus mixed forest; community D: broadleaved mixed forest) in the Xiaoliang Experimental Station were compared with a local secondary tropical evergreen monsoon forest to study the feasibility of forest restoration in the tropical areas. The results indicated the composition structure and spatial pattern of the three antificial forests became more complicated and stable from community B to community C and to community D, and developed gradually toward the local tropical monsoon forest. The studies on community similarity also indicated that community D was the most similar to the local tropical monsoon forest. Therefore, with some engineering and biological measures, after some pioneer trees are planted in extremely degraded tropical areas,the pioneer forest should be reformed by multilayer and multispecies broad leaved mixed forest in time, wihich could accelerate the development of artificial forest into local climax community.

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.
