摘要
本文建立了干旱区湖泊水质的非线性数学模型 ,我们考虑了湖水的强烈蒸发因素 ,给出了适合干旱区的二维浅水湖的运动学方程组和污染物浓度场的扩散方程 ,作为水质分析的数学模型 ,对博斯腾湖两个典型水文年的矿化度浓度场进行了模拟计算 ,结果与实测值基本吻合 ,从而验证了该模型的准确性与可扩展性 .
In this paper, a non-Uniform, mixed type model for predicting the water quality of the Lakes in arid desert basins areas is presented. The law of variation describing the movement, distribution and concentration of pollution in the lake is controlled by a group of equations,with corresponding boundary conditions numerical computation and verification are made for the concentration field of mineralization and the result coincides with the data of observation, therefore,the program can be the mathematical model for predicting the water quality of the lakes in arid desert basins areas.
