莲花山白盆珠省级自然保护区2017年——2023年森林动态变化研究

Study on Forest Dynamic Change in Baipenzhu Provincial Nature Reserve of Lianhuashan from 2017 to 2023

根据莲花山白盆珠保护区2017年建立的3个1 hm~2森林固定监测样地数据,分析了保护区2017年—2023年6年间的森林碳密度变化。研究表明,经过6年的自然更新,3个样地的物种数、个体密度和碳密度均有明显变化。通过分析样地主要树种的碳储量变化发现,大头茶、罗浮锥、广东润楠、黄樟、华润楠是适合南亚热带碳汇造林的优良阔叶树种。

According to the monitor data from three 1-hectare fixed plots established in Baipenzhu Provincial Nature Reserve of Lianhuashan in 2017,we analyzed the variation of carbon density of the forest in the reserve between 2017 and 2023.This study revealed that,after six years of natural regeneration,there were significant changes in species richness,individual density,and carbon density in the three plots.By examining the carbon storage changes of the dominant tree species in the plots,it was found that Camellia grandiflora,Castanopsis hystrix,Phoebe bournei,Cryptocarya concinna,and Cryptocarya chinensis are suitable broadleaf tree species for afforestation for carbon sink in the South Asian tropics.
