摘要
由于对混交林的研究数量有限,很难准确预测混交林的成功,特别是在生长、林下多样性和固碳潜力方面。本研究探讨了三种不同林分组合下五角木、冬绵、香柏木和花茶对林分生长、林下多样性和固碳潜力的影响。选择15年32公顷的混合树种林分组合作为研究对象。根据种属组合对种群进行分层。巢式样地(25 m × 25 m)随机设置在不同的种林分组合中,收集生长数据。在每个巢状样地随机设置1 m × 1 m样地,进行林下植物多样性研究。结果表明,五角木和毛缕木两种林分组合在生长、固碳和含碳量方面均优于其他林分组合。而三种林分组合样地的树苗多样性更高。4种林分组合样地的有效种数、物种丰富度、均匀度和优势度均较高。通常情况下,五角木和毛缕草是相容的,因为它具有最高的生长和碳固存潜力。
Growth Performance, Undergrowth Diversity and Carbon Sequestration Potentials of Tree Species Stand Combinations, Ghana
The limited number of studies on mixed plantations makes it difficult to accurately predict success of mixed-species combination especially with regards to growth, undergrowth diversity and carbon sequestration potentials. This study therefore provides information on the effects of Ceiba pentandra, Terminalia superba, Cedrela odorata and Khaya anthotheca in three different stand combinations on growth, undergrowth diversity and carbon sequestration potential. A 15-year-old coupe of 32 ha of mixed tree species stand combinations was selected for the study. The coupe was stratified based on the species combinations. Nested sub-plots (25 m × 25 m) were randomly laid in different species stand combinations for growth data collection. In each nested sub-plot, 1 m × 1 m plots were also randomly laid for undergrowth diversity study. The results revealed that two species stand combination of Ceiba pentandra and Terminalia superba performed better in terms of growth, carbon sequestration and carbon content as compared to the other species stand combinations. The saplings on the other hand, were more diverse under the three species stand combination plots. Also, the effective number of species, species richness, evenness, and dominance were higher in the four species stand combination plots. Generally, Ceiba pentandra and Terminalia superba are compatible as it produced the highest growth and carbon sequestration potential.
