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 本文以珠江水體、懸浮物為研究對象,通過對西江馬口、北江河口、東江博羅斷面水體取樣,分析水體中不同形態碳含量,測定碳同位素值,并計算了河流碳通量值;還對珠江流域的侵蝕狀況及植被分布對流域侵蝕的影響進行了探討。

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 接著在gis支持下,選取以上8項土壤肥力要素并加上土壤質地作為參數,以各要素圖層疊加產生的圖斑作為評價單元,修改內梅羅公式,對武進市土壤肥力質量進行綜合評價,得出:土壤肥力質量中等偏下,其中,沿江圩田區、孟河平田區、太涌平田區和低山丘陵區主要處于“較差”水平,而鄭橫圩田區、沿湖圩田區、洮?平田區主要處于“中等”及“良”水平。

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 首先就機械和化學風化兩種不同的陸地侵蝕機制在提供河流碳源方面所發揮的不同作用作了詳細論述,并比較了季風流域和非季風流域間河流碳輸移在通量及性質上的差異。

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,人類活動對陸地侵蝕沉積過程及河流碳循環所產生的直接或間接的影響也有待于今后繼續深入探索。

But geochemical studies have suggested that little of the riverine carbon , derived from plants , actually makes it out 但是地球化學的研究卻顯示:河流中的碳,源自植物,實際上很少會流入海洋。

The riverine carbon transport is closely related to the processes of terrestrial erosion - deposition 摘要河流碳輸移與陸地侵蝕沉積過程緊密相關。
