本文对河口的情况进行简化后,提出了一维的数学模式,导出了河口区非保守元素的含量与盐度的关系,讨论了河口区元素的平衡,并得出:(1)非保守元素在河口区的转移情况,除与化学和生物过程有关外,与河流的物理过程也有较密切关系;(2)在研究河口区元素的转迁时,应同时观测某些物理参数,可估计出河口区元素的平均逗留时间,这是一个有用的参数;(3)由于河口区情况不同,研究元素迁移时,测定方法的精度是需要考虑的。
After simplifying the estuary, this paper proposed a one-dimensional mathematical model, derived the relationship between the content of non-conservative elements and salinity in the estuary area, discussed the equilibrium of the estuarine elements, and concluded that: (1) non-conservative elements In addition to the chemical and biological process, the migration in the estuary area is also closely related to the physical process of the river. (2) When studying the estuarine element transition, some physical parameters should be observed at the same time, which can be estimated The average residence time of estuarine elements is a useful parameter. (3) Due to the different conditions in estuarine areas, the accuracy of the method for determining the migration of elements should be considered.
