武夷山国家公园常绿阔叶林生物量分析
Analysis of Biomass in Evergreen Broad-Leaved Forests of Wuyishan National Park
摘要
Abstract
In Wuyishan National Park,fixed plots were established in evergreen broad-leaved forests with homogeneous habitats.From 2018 to 2023,we analyzed the dynamics of stand density,biomass,stock volume,and carbon storage across different diameter classes based on monitoring indicators,including plant number,diameter at breast height(DBH),and tree height,measured in the sample plots.The results showed that:(1)The stand density of the evergreen broad-leaved forest in Wuyishan National Park decreased as the DBH increased,forming an inverted"J"-shaped distribution,while biomass,stock volume,and carbon storage increased with DBH.Plants with DBH>30 cm had significantly higher biomass,stock volume,and carbon storage than those in other DBH classes(P<0.05).(2)The stand density of plants with DBH 1～5 cm decreased by 6.61%,while that of other DBH classes increased to varying degrees.Among them,plants with DBH 5～10 cm increased by 18.93%,showing a significant change(P<0.05).(3)The biomass,stock volume,and carbon storage increased across all DBHclasses,and plants with DBH>30 cm showed significant increases of 38.47 m3·hm-2 and 44.56 t·hm-2 in stock volume and carbon storage,respectively(P<0.05).The evergreen broad-leaved forest communities in Wuyishan National Park exhibit a relatively stable structure but have not yet reached the climax succession stage,with potential for further enhancement in productivity and carbon sequestration capacity.关键词
