| 摘 要： | 在分析长潭自然保护区不同功能区土壤有机碳分布时，本研究发现，不同功能区土壤有机碳差异显著（P〈0．05），土壤有机碳含量为实验区〉缓冲区〉核心区；不同功能区各层土壤有机碳含量为：0～50cm土层土壤有机碳含量为实验区〉缓冲区〉核心区．50～100cm土层土壤有机碳含量为缓冲区〉实验区〉核心区，缓冲区土壤有机碳含量变化大于核心区与实验区。 |

| Abstract: | Spatial variability of SOC content of Changtan Nature Reserve was affected by different management regimes, i. e, the core zone, buffer zone, and experimental zone. Result showed significant difference in SOC contents existed among different management regimes（p 〈 0.05）, with a trend of SOC content in experiment zone 〉 buffer zone 〉 core zone, due to vigorous afforestation projects in the experimental and buffer zones. By stratum, SOC content in the 0 - 50 cm stratum showed ： experiment zone 〉 buffer zone 〉 core zone, while in the 50 - 100 cm stratum, the trend was： buffer zone 〉 experiment zone 〉 core zone. The variability of SOC content within buffer zone was greater than that within the core zone or experimental zone. |
