摘要
在分析九龙江河口海域流态和污染规律的基础上，考虑盐淡水混合河口海域的污染物非线性扩散现象，用有限元解法进行数值分析计算，并对数值解的稳性进行了探讨，通过计算值与实测值的比较、验证，具有较好的精度．
On the basis of analyzing the now regime and pollution pattern of the sea area of Jiulong Jiang Firth, the pollutant nonlinear diffusion phenomenum in the seaward firth with mixed-up salt and fresh water is taken into consideration. The finite element method is used for conducting numerical analysis and the stability of the numerical solution is investigated. Compering the calculation value with the measured one, it is verified that the result obtained has better accuracy.
