摘要
通过胶州湾1991年5月至1994年2月的实测数据的分析,展示了Si∶N比值起因和Si生物地球化学过程,并且建立初级生产力与Si∶N的比值的动态方程。利用非保守性物质Si∶N比值作为湾内水的示踪剂,根据海湾的水交换完成的定义及海湾的充满和放空原理,应用作者提出的生物地球化学模型,计算得到胶州湾水交换时间的集合X={x︱10<x<15},其平均值为12.5 d。作者首次提出了新的海湾水交换时间(marine bay water exchange time)定义,包括从两个方面:海湾的充满和海湾的放空,来说明此定义。作者首次探讨了非保守性物质情况下,来确定海湾水交换时间的范围。作者首次给出了海湾水交换完成的定义,并且首次提出了海湾充满和放空的原理,然后利用了保守性物质或者非保守性物质作为湾内水的示踪剂,采用生物地球化学模型,计算得到海湾水交换时间的范围。作者的海湾水交换研究不需要以潮流动力学为背景,也不受到潮流模型的参数和变量影响。
By the analysis of the monitoring data from May 1991 to February 1994 in Jiaozhou Bay,the results showed the origin of specific value Si∶ N and the biogeochemical process of Si,and the dynamic equation of primary production and specific value Si∶ N.Using the non-conservative matter：the specific value Si∶ N,as a tracer,and according to the definition of marine bay water exchange accomplishment and the principle of marine bay filling up and discharging empty,and then applying the biogeochemical model put forward by the authors,calculated was the Jiaozhou bay water exchange time＇s aggregate：X={x︱10x15},unit：day,its average value：12.5 days.These calculation processes and results were proved and supported by the primary production variation,the critical value of nutrient Si concentration limiting the phytoplankton growth,the spatial and temporal distribution of nutrient Si concentration,and the results calculated by Chen＇s numerical model（1982）,by Wu＇s box model（1992）and by State Oceanic Administration and Qingdao Aquatic Administration＇s numerical model（1998）.The authors first put forward the new definition of marine bay water exchange time,which was explained by the two different aspect：marine bay filling up and discharging empty.The authors first probed into the fact that the range of marine bay water exchange time was determined in the case of using the non-conservative matter as a tracer.The authors first put forward the definition of marine bay water exchange accomplishment and the principle of marine bay filling up and discharging empty,and used the conservative matter and non-conservative matter as tracers in water body inside the bay,and applied the biogeochemical model,and then calculated the range of marine bay water exchange time.The authors＇ study on marine bay water exchange would not need the background of tidal dynamics,or would not be affected by the parameters and variables of the tidal model.
