Riverine carbon flux and continental erosion 河流碳通量与陆地侵蚀研究
2.
The riverine carbon transport is closely related to the processes of terrestrial erosion - deposition 摘要河流碳输移与陆地侵蚀沉积过程紧密相关。

But geochemical studies have suggested that little of the riverine carbon , derived from plants , actually makes it out 但是地球化学的研究却显示：河流中的碳，源自植物，实际上很少会流入海洋。

In addition , we should further explore direct or indirect impacts of human activities on the processes of terrestrial erosion - deposition and the riverine carbon cycle 此外，人类活动对陆地侵蚀沉积过程及河流碳循环所产生的直接或间接的影响也有待于今后继续深入探索。

Using radiocarbon techniques on sediments collected from four rivers , they determined that bacteria may alter riverine carbon , making it indistinguishable from ocean carbon 科学家以放射性碳技术研究收集自四条河流的沉积层，发现细菌可以改变河水里的碳，使它与海水里的碳无法区别。

This paper firstly reviews two different kinds of terrestrial erosion ( the mechanical and chemical weathering mechanisms ) , discusses their respective roles in providing carbon to the river , and compares the differences between the monsoon and non - monsoon drainage basins in flux and the characteristic of the riverine carbon transport 首先就机械和化学风化两种不同的陆地侵蚀机制在提供河流碳源方面所发挥的不同作用作了详细论述，并比较了季风流域和非季风流域间河流碳输移在通量及性质上的差异。

Then , with the help of gis , i selected 8 soil fertility factors mentioned above and soil texture as parameters , used blocks generated by overlaying each factor theme as assessing unit , modified nemoro fomular , and then i assessed the overall soil fertility quality of wujin city , we know : the soil fertility quality of the city is generally medium or worse , in it , the district of riverine polder the district of menghe even fields the district of taige even fields and the district of hilly lands are on " worse " level , and the district of zhengheng polder the district of lakeside polder and the district of taoge even fields are on " medium " or " better " level 接着在gis支持下，选取以上8项土壤肥力要素并加上土壤质地作为参数，以各要素图层叠加产生的图斑作为评价单元，修改内梅罗公式，对武进市土壤肥力质量进行综合评价，得出：土壤肥力质量中等偏下，其中，沿江圩田区、孟河平田区、太涌平田区和低山丘陵区主要处于“较差”水平，而郑横圩田区、沿湖圩田区、洮?平田区主要处于“中等”及“良”水平。

This paper researches on the water and suspension in zhujiang ( pearl ) river and her three branches , sampling in makou hydrological gorge station of xijiang river , hekou hydrological gorge station of beijiang river and boluo hydrological gorge station of dongjiang river . the author calculated the riverine carbon flux and measured the content of different carbon forms and carbon isotope composition . furthermore , the author also studied drainage basin erosion and the influence of vegetation distribution on erosion 本文以珠江水体、悬浮物为研究对象，通过对西江马口、北江河口、东江博罗断面水体取样，分析水体中不同形态碳含量，测定碳同位素值，并计算了河流碳通量值；还对珠江流域的侵蚀状况及植被分布对流域侵蚀的影响进行了探讨。
