摘 要:采用主成分分析法并结合MATLAB工具辅助计算,以阜新新邱露天煤矿排土场附近地下水污染区的水质监测点进行案例分析.从所有的污染因子中确定出主要的污染因子,对监测点进行了优化分类.通过实例计算对主成分分析中数据预处理方法进行了讨论,比较了标准化变换和归一化变换两种方法的计算结果,并对各组监测的优化点逐一作可靠性检验.结果表明,采用两种数据预处理方法所得结果基本一致,都可在分析中使用,各组优化点与其它点之间不存在明显的系统误差.By principal components analysis and MATLAB auxiliary tool, the case analysis was carried out by taking an example of the monitor of groundwater pollution area near the waste dump of open pit coal mine of Xinqiu in Fuxin. Main pollution factors were determined from all the pollution factors, and the monitors were optimized. The data pretreatment methods of principal components analysis were discussed by the calculation of this example; the calculation results were prepared with the two methods of standardization and normalization, and feasibility test for the optimization pollution factors of groups of monitoring. The result shows that the results analyzed with two kinds of pretreatment methods of data are basically consistent, and there is not consist in obvious system errors for groups of the optimization points and others points.
