摘要
以水文地球化学理论和水文随机模拟技术为基础,利用水文地球化学模拟方法对关中盆地混合地下热水中主要离子与主要离子总含量TDI的关系进行分析,采用最小二乘法及根据残差的偏态系数进行参数估计以确定最适线性方程定量模拟关中盆地水化学场的混合作用对水化学成分的影响.研究结果表明:关中盆地地下热水中的主要离子矿化度与TDI之间具有良好的相关关系,不同分区与TDI相关程度较高的离子类型有所差异,地下热水混合作用产生的一系列过渡型地下水的化学成分可以利用线性方程y=Ax+B得到较好的模拟结果.
Based on the hydrogeochemical theory and stochastic simulation technology,a quantitative analysis of the relationship between TDI and the main ionic mineralization of the underground thermal water in the Guanzhong Basin was conducted through hydrogeochemical simulation.According to the residual skewness coefficient and the least square method,the most suitable linear equation was determined for simulating the mixed effect on the chemical composition of the underground thermal water in the basin.The results show that there is a good correlative relationship between the mineralization of the main ions and TDI,that in different areas the ions with close correlation with TDI are different,and that the chemical composition of a series of transitional groundwater can be well simulated through the linear simulation equation y=Ax＋B.
