摘要
本文针对地区性的重金属污染评价和污染源的确定进行了充分的分析与合理的假设,利用MATLAB将所给数据进行整合,从高污染浓度点所在区域分析出大致的污染原因,利用SPSS分析数据得到各污染元素的相关性以及主要原因的贡献度,确定污染的主要原因,并建立二维离散模型。
In this essay, regional heavy metal pollution assessment and the determination of pollution source are fully analyzed and reasonably assumed. The given data is integrated with MATLAB, and the pollution reasons are analyzed according the area where has high pollution concentration. Subsequently, the relativity of each pollution element and the contribution degree of main reason is obtained with SPSS, so the main reason of pollution can be determined. At last, a two-dimensional separation model is built. -
