摘要
按照LOICZ的模拟指南 ,九龙江河口区采用单箱模型模拟其生物地球化学元素的通量。结果表明 ,九龙江河流输入进河口系统的DIP通量为 2 .81× 10 7mol/a ,交换流带入河口区DIP通量为 10 .93× 10 7mol/a ,因此 ,净沉淀量为 8.0 5× 10 7mol/a。九龙江河流输送进河口系统的DIN通量为 73.47× 10 8mol/a ,它远高于DIP的通量。因此 ,此河口区系统内部有 7.6 6× 10 8mol/a的差额才能达到平衡。
The LOICZ biogeochemical element budget model was tested in Jiulong River Estuary, the result indicated that riverine input ot DIP is 2.81×10 7mol/a, and the DIP of 10.93×10 7mol/a of mixing flow is significantly larger than to DIP from river and residence flow, so the net internal sink of DIP totals 8.05×10 7mol/a across the system. The DIN input from river is 73.47×10 8mol/a which is much larger than the DIP from residence flow and mixing flow. The internal sink of △DIN, is 7.66×10 8mol/a in order to balance the river input.
