摘要

退耕还林等土地利用变化影响着土壤有机碳(SOC)的累积。笔者设置LA(天然马尾松林地)、LB(桤木林地,2002年营造,之前为玉米地)、LC(玉米地)3类采样区,将土样按粒径分为3类,再分离为8种土壤团聚体组分,测定所有组分SOC和δ¹³C值。利用土壤团聚体组分和稳定性碳同位素(¹³C)技术探讨三峡库区农地造林后SOC的动态累积机制。结果表明:农耕使0～10 cm土层的SOC密度降低了57.2%,≥10～30 cm土层的降低了32.2%; 而退耕造林11 a后的桤木林0～10 cm土层的SOC密度增加了34.5%,≥10～30 cm土层的增加了42.9%; 其中源自桤木林的“新碳”在0～10 cm土层中占48%,≥10～30 cm土层占52%,土壤原先存储的“旧碳”仅损失了9.2%,造林增加SOC含量的原因可能是增加了“新碳”的固定能力,加强了对原存贮的“旧碳”的物理保护。

Abstract

Land use change such as conversion of cropland to forest strongly affects the soil organic carbon(SOC)sequestration.The objective of this paper was to assess the dynamics mechanism of SOC sequestration in protection forest in Three Gorges reservoir area by means of organic matter fractionation and stable C isotopes(δ¹³C)technology. The soil of three land use patterns(LA. a permanent Pinus massoniana forestland, LB. a deciduous Sycamore maple forestland was planted on continuous maize field in 2002, LC. a continuous maize field)were sampled. Soil samples were separated into three aggregate size classes. And inter-vs.intra-aggregate particulate organic matter were isolated into eight soil aggregate fractionations by density method. All fractions were analyzed for their SOC content and δ¹³C. Results showed that long-term agricultural used land significantly decreased SOC content by 57.2%and 32.2% in the top 10 cm and in the ≥10-30 cm depth layer, respectively. But after 11 years afforestation, the total amount of soil C increased by 34.5% and 42.9% in the 0-10 cm and in the ≥10-30 cm depth layer, respectively. Forest-derived carbon(new C)contributed 48% and 52% to the total SOC storage in the afforested systems in the 0-10 cm and ≥10-30 cm depths, respectively. The stored SOC before 2002(old C)only lost by 9.2%in LB. Afforestation could significantly increase new SOC fixed and improve the old SOC physically protected.
