摘要:
研究以小班为基本研究单元,按起源分林龄对广东省肇庆市国有北岭山林场生态公益林碳储 量进行了研究。国有北岭山林场乔木林总碳储量为 278.0×106kg,其中生态公益林碳储量为 244.9×106kg。生态公益林中天然林在不同林龄间的林分间平均碳密度不存在显著差异,范围(25.24±1.02)~ (28.01±1.69)×103 kg/hm2;而人工林则存在显著的差异,以 20~40 a 林龄的林分最大,为(34.22±2.77) ×103 kg/hm2,其次为大于 40 a 林龄的林分,为(23.34±0.72×103kg/hm2。在 20~40 a 林龄的生态公益林中,人工林平均碳密度显著大于天然林,但在大于 40 a 林龄的林分中,则显著小于天然林。

Abstract:
Abstact The carbon storage and carbon density of ecological forest in Beilingshan State-owned Forest Farm were studied according to the forest origin and the stand age based on the forest compartment resource datasets. The total carbon storage was 278.0?103Mg and the carbon storage of ecological forest was 244.9?103Mg in Beilingshan State-owned Forest Farm. There were no significant differences in the average carbon density among the secondary forests with different age of ecological forest, and the average carbon density ranges from 25.24?1.02Mg/ha to 28.01?1.69Mg/ha. There were significant differences in the average carbon density among the plantations with different age of ecological forest, and the highest average carbon density (34.22?2.77Mg/ha) was observed in the 20?40 years old plantation followed by the >40 years old plantations (34.22?2.77Mg/ha). Among the 20?40 years old ecological forests, the average carbon density in the plantation was significantly larger than the secondary forest and vice versa among the >40 years old ecological forest.
