摘要：【目的】为热带森林固碳增汇措施和精准评估海南生态碳汇对实现“碳中和”目标的贡献提供基础数据和科学依据。【方法】本研究利用最新的森林资源二类调查分布数据和野外监测样地调查资料,采用空间统计分析等方法,研究了海南热带雨林国家公园森林生态系统碳储量及其变化特征。【结果】结果表明:国家公园森林生态系统总碳储量为89.67 Tg,其中植被、土壤和凋落物的碳储量分别为39.38,49.65和0.64 Tg,所占比重依次为43.92%,55.37%和0.71%。森林生态系统平均碳密度为158.62 Mg/hm^(2),其中植被层、凋落物和土壤碳密度分别为95.91,1.55和120.91 Mg/hm^(2)。天然林和人工林生态系统碳储量分别为77.41和12.26 Tg,分别占总储量的86.33%和13.67%。不同植被类型中,热带雨林低地雨林和山地雨林的碳储量最高(73.94 Tg),占总碳储量的82.45%;热带山地雨林的碳密度最高(289.52 Mg/hm^(2)),最低为灌木林(81.95 Mg/hm^(2))。海南热带雨林国家公园森林生态系统碳汇平均强度为1.84 Tg/a。【结论】海南热带雨林国家公园森林生态系统具有较高的碳储量和碳密度,固碳能力较强。未来应加强天然林保护和低效林生态修复,进一步提升森林生态系统固碳增汇能力。
【Objectives】It will provide basic data and scientific basis for the carbon sink enhancement measures of tropical forests,and the accurate assessment on the contribution of ecological carbon sink in Hainan Island to the goal of carbon neutrality.【Methods】In this study,the latest data from forest resources surveys and forest plots were used to study the forest ecosystem carbon storage and its variation characteristics in National Park of Hainan Tropical Rainforest(NPHTR)by spatial statistical analysis.【Results】The results were as follows:the total ecosystem carbon storage of NPHTR was 89.67 Tg,and the carbon storage of vegetation,soil,and litterfall was 39.38,49.65,and 0.64 Tg.The ratio of the ecosystem was 43.92%,55.37%,and 0.71%.The ecosystem carbon density of NPHTR was 158.62 Mg/hm^(2),and the carbon density of vegetation,litterfall,and soil were 95.91,1.55,and 120.91 Mg/hm^(2) respectively.The carbon ecosystem carbon storages of the natural forest and the planted forest were 77.41 and 12.26 Tg,and the ratios were 86.33% and 13.67%.The carbon storage of tropical lowland rainforest and mountain rainforest were the biggest ones of tropical forest,and the ratio is 82.45%.The carbon density of the tropical mountain rainforest(289.52 Mg/hm^(2))was the biggest one of tropical forests,and the smallest one was in the shrub(81.95 Mg/hm^(2)).The carbon sequestration of tropical forests in NPHTR was 1.84 Tg/a.【Conclusions】The amount of forest ecosystem carbon storage,carbon density and carbon sequestration NPHTR is bigger than in other ecosystem.In the future,it is important to strengthen the protection of natural forests and ecological restoration of planted forests,to improve the quality of forests,and to increase the carbon sequestration of tropical forest ecosystems.
