1995年3个航次调查研究结果表明，九龙江口水体总有机物的含量受悬浮物含量控制。在S＜5的低盐度区，悬浮泥沙和有机物产生明显的絮凝沉降；在S＞5的广阔海域，它们的迁移接近于理想混合。估算得出九龙江河流的入海通量约：悬浮泥沙为9．8×105t／a；总COD为3．2×104t／a，其中溶解态COD为2.1×104t／a，约占2／3，为水体有机物的主要形态，如换算为溶解有机碳，则DOC的平均通量为3．2×104t／a。
The survey results of three voyages in 1995 showed that the total organic matter in Jiulong River Estuary was controlled by the suspended matter content. In the low salinity area of S <5, the suspended sediment and organic matter produced obvious flocculation and sedimentation; in S> 5, their migration was close to ideal mixing. It is estimated that the flux of water entering the Jiulong River reaches about 9.8 × 105t / a for suspended sediment, and the total COD is 3.2 × 104t / a. The dissolved COD is 2.1 × 104t / a, accounting for about 2 / 3, the main form of organic matter in water, such as dissolved organic carbon, the DOC average flux of 3.2 × 104t / a.
