摘要
为评价农产品加工对企业周边地下水水质的影响,采用主成分和聚类分析10个不同类别的农产品加工企业周边地下水样的8个水样指标,测定其p H值、铵态氮(NH_4^+-N)、COD_(Mn)、总硬度、硫酸盐、砷、阴离子表面活性剂和溶解性总固体。通过主成分分析提取出3个主成分,应用聚类分析对该3个主成分的得分进行聚类,聚类分析后水样划分为4类,相同类型的农产品加工企业位于一类,根据加工企业的类型可分析和判别其可能的污染情况。
To evaluate the effect of processing agricultural products on the quality of surrounding groundwater,principal component and cluster analysis were used to analyze 8 indexes of 10 water samples from different categories of agricultural products processing enterprises. p H,ammonium nitrogen,CODMn,total hardness,sulfate,arsenic,anion surfactant and TDS were detected separately. 3 principal components were extracted by principal component analysis. Then cluster analysis was used to cluster the scores of the three principal components. After cluster analysis,the water sample is divided into 4 categories. The same type of processing agricultural products is located in one category. Therefore,the possible pollution situation can be analyzed and distinguished according to the type of processing enterprises.
