摘要:
以新垦植橡胶林、成熟橡胶林、高海拔橡胶林为研究对象,对其进行人为固碳增汇管理,比较三种复合农林模式橡胶林与同条件下橡胶纯林的植被碳储量及其未来固碳潜力,并分析三种复合农林橡胶林土壤碳储量。植被生物量碳储量通过各类增汇植物的生物量回归模型、热带树种生物量通用模型、异速生长模型进行拟合预测; 土壤碳储量通过土壤剖面分层采样(0～10 cm,10～20 cm,20～30 cm,30～50 cm,50～100 cm)进行估算。研究显示:1. 复合农林橡胶林现存生物量碳储量为1.19～52.89 t/hm2,10 a后固碳潜力为1.28 ～106.08 t/hm2,20 a后固碳潜力为2.23～233.89 t/hm2; 2. 林下添加增汇植物后土壤碳储量显著高于橡胶林,新垦植模式中,橡胶+大叶千斤拔土壤碳储量比橡胶林增加54.95 t/hm2; 成熟橡胶林模式中,橡胶+大叶千斤拔土壤碳储量比橡胶林增加35.58 t/hm2,橡胶+可可土壤碳储量比橡胶林增加4.33 t/hm2。结果表明:构建复合农林橡胶林可总体提高橡胶林植被碳储量及固碳潜力,提高土壤碳储量,但增汇植物种类、种植密度、生长速度不同,固碳潜力大小不一。
Abstract:
Carbon sequestration management was operated in newly-planted rubber plantations, mature rubber plantations and high-altitude rubber plantations. We compared vegetation carbon storage, carbon sequestration potential, and soil carbon storage in different agro-forestry systems and pure rubber plantations. The vegetation carbon storage was estimated by tree biomass regression model, tropical trees biomass universal model, and allometric model. Soil carbon storage was estimated by soil profile stratified sampling(0～10 cm, 10～20 cm, 20 ～30 cm, 30～50 cm, 50～100 cm). The results showed: 1. The existing biomass carbon storage was 1.19～52.89 t/hm2, and the carbon sequestration potential was 1.28～106.08 t/hm2 in 10 years later and 2.23～233.89 t/hm2 in 20 years later. 2. After carbon sink plants were added in rubber plantations, soil carbon storage was significantly higher than that of pure rubber plantations. For newly-cultivated rubber plantations, soil carbon storage of rubber with flemingia macrophylla increased 54.95 t/hm2 than that of pure rubber plantations; for mature rubber plantations, rubber with flemingia macrophylla increased 35.58 t/hm2, and rubber with cocoa increased 4.33 t/hm2. The carbon sequestration management can improve the overall vegetation carbon storage and carbon sequestration potential, meanwhile increase soil carbon storage. However, carbon sequestration potential varies due to different plant species, planting density, and growth rates.
