| Abstract: | 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. |
