| 英文摘要 | The dynamics of total organic carbon (TOC) in hydrological processes are important for understanding carbon cycling in forest ecosystems. TOC was monitored in precipitation, throughfall, stemflow, litter leachate and runoff in subtropical climax forestecosystem-monsoon evergreen broad-leaved forest (MBF), and its two successional forests of natural restoration-mixed Pinus mas-sonniana/broad-leaved forest (PBF), and Pinus massoniana forest (PF) at Dinghushan Nature Reserve (DNR) in southern China for 3 years (from April, 2002 to May, 2005). The major results and conclusions are as follows: TOC concentrations and fluxes of through- fall (DTF), stemflow, and litter leachate in PF were higher than those in MBF and PBF. TOC concentrations in dry season werehigher than that in rainy season, while TOC fluxes were in opposite situation. The contributions of different hydrological processes toforest SOC pools decreased in the order: litter leachate >DTF >stemflow. Forest canopy and litter appeared to be important sourcesfor TOC. Therefore, large TOC fluxes imported to soils with small amount of outputs by runoff may result in SOC accumulation.The net inputs of organic carbon to soil profile from the hydrological processes in MBF, PBF and PF were (27.1 ± 1.65) g·m -2 ·a -1 ,(28.9 ± 2.79) g·m -2 ·a -1 , (30.2 ± 2.65) g·m -2 ·a -1 , respectively. This part of carbon is usually negligible because it is only a small pro-portion of SOC. However, this part of carbon could be imported into the soil through infiltration. Through soil filtration and adsorp-tion, carbon should be distributed in soil evenly, which is helpful to long-term preservation of SOC. |
