摘要

摘要: 在西江下游的马口水文站对径流进行了4个季节的有机碳采样分析。研究表明,西江径流有机碳的断面构成在各个季节均较为一致;季节性变化表现为,有机碳和悬浮物含量随流量的增加而增加。随着水体悬浮物含量的增加,悬浮物的有机碳含量呈对数趋势降低。西江流域的有机碳侵蚀通量为10.18×106gC/km²·yr.,是全球外流域有机碳侵蚀通量的2～3倍,其中以颗粒有机碳的侵蚀通量为主,达到8.30×106gC/km²·yr.,溶解有机碳的侵蚀通量为1.88×106gC/km²·yr.。反映了流域内较强的机械剥蚀过程,这与西江流域典型的季风气候、较大的地形高差,以及农业耕作历史长久、土地利用强度较大等因素有关。

Abstract: Riverine water samples were collected from the lower reach hydrometric station of Xijiang River, namely Makou, in four hydrological seasons. The samples were analyzed of their organic carbon. The analysis results demonstrated that the distribution of organic carbon, including particulate organic carbon (POC) and dissolved organic carbon (DOC), is fairly suitable in the sampling section in every season. The contents of organic carbon and total suspended substance (TSS) in riverine water body varied seasonally with the discharge in a positive pattern. With the content of total suspended substances increasing, the quality partition of organic carbon in TSS decreased in a logarithm tendency. The weathering flux of organic carbon in Xijiang River drainage area is about 10.18×10 6gC/km ²·yr., which is two to three times in quantiy of the average value in the global external drainage area. The POC is the main constitute of the riverine organic carbon, which weathering flux is about 8.30×10 6gC/km ²·yr. The weathering flux of dissolved organic carbon is about 1.88×10 6gC/km ²·yr. The mechanical erosion is very intense in this drainage area, which is considered to be related to the typical monsoon climate and to the comparatively great undulation of the landforms in this drainage basin. The long history and fairly intense utility of the land for agriculture use are all responsible for the serious soil erosion in this area.
