这项研究的目的是通过确定和描述布隆迪Kigwena和Rumonge森林植物群落的特征来描述其植被的空间异质性。这项研究还强调了这两个森林的社会学组织，并有助于了解布隆迪森林生态系统的植物社会学，而布隆迪的森林生态系统仍然不完整。分析的基础是从基格韦纳森林的23个植物社会样地和鲁蒙日森林12个样带的胸径测量数据。分别鉴定了4个植物群落和3个植物群落，并对它们的高级分类群(纲、目和联盟)进行了分类。在基格韦纳森林，植被的类型学遵循湿度和人类化梯度。森林边缘效应明显影响植物群落的生物多样性。然而，在鲁蒙日森林中，植被的异质性似乎与相同植被背景下的局部退化现象相对应。
The aim of this study is to describe the spatial heterogeneity of the vegetation of the Kigwena and Rumonge forests in Burundi by identifying and characterizing their plant communities. The study also highlights the sociological organization of the two forests and contributes to knowledge on the phytosociology of Burundi’s forest ecosystems, which is still fragmentary. The analyses are based on data collected from 23 phytosociological plots in Kigwena forest and from measurements of tree diameter at breast height along 12 transects in Rumonge forest. Four and three plant communities, respectively, were identified and characterized and their higher taxa classified (class, order and alliance). In Kigwena forest, the typology of the vegetation follows a moisture and anthropisation gradient. The forest edge effect clearly influences the biological diversity of the plant communities. In Rumonge forest, however, the heterogeneity of the vegetation seems to correspond to local degradation phenomena in the same vegetation context.
