Lianas play significant ecological roles in tropical forest ecosystems, so knowledge of the factors that affect them is key to forest management. Nonetheless, there is limited information on how wildfires influence liana communities. This study therefore sought to determine the effects of wildfires on liana community structure and liana–soil associations in the Asenanyo Forest Reserve, Ghana. Thirty plots (20 × 20 m) were established in each of three forest stands (9-month-old burnt, 15-year-old burnt, unburnt) and sampled for lianas (diameter at 1.3 m from the rooting base ≥ 1 cm). Liana diversity, abundance and basal area were significantly lower in the two burnt forest stands. The 15-year-old burnt forest supported significantly higher values for these liana community attributes than the 9-month-old forest. There was a shift in liana species composition towards a more homogenized composition in the burnt forest. Liana–soil associations differed between the unburnt forest on the one hand and the two burnt forests on the other. Thus, in all, fire caused shifts in liana community structure and liana–soil associations in the forests. The findings of the study have implications for liana, fire and forest management.

野火导致加纳潮湿半落叶林中藤本植物群落结构和藤本植物-土壤关系发生变化

藤本植物在热带森林生态系统中发挥着重要的生态作用，因此了解影响它们的因素是森林管理的关键。尽管如此，关于野火如何影响藤本植物群落的信息有限。因此，本研究试图确定野火对加纳 Asenanyo 森林保护区藤本植物群落结构和藤本植物-土壤关联的影响。在三个林分（9 个月大的被烧毁、15 年被烧毁、未烧毁）中的每一个中建立了 30 个地块（20 × 20 m），并对藤本植物（距离生根基部 1.3 m 处直径 ≥ 1 cm 处的直径）进行取样. 在两个被烧毁的林分中，藤本植物的多样性、丰度和基底面积显着降低。与 9 个月大的森林相比，15 年历史的烧毁森林支持这些藤本植物群落属性的值要高得多。在被烧毁的森林中，藤本植物的物种组成向更均匀的组成转变。一方面，未烧毁的森林和另一方面的两个烧毁的森林之间的藤本植物 - 土壤关联不同。因此，总的来说，火灾导致了森林中藤本植物群落结构和藤本植物-土壤关联的变化。研究结果对藤本植物、火灾和森林管理有影响。
