AN ATTEMPT TO USE MULTIVARIATE ANALYSIS IN THE STUDY OF GROUNDWATER POLLUTION TREND——TAKING KARST GROUNDWATER IN XUZHOU CITY AS AN EXAMPLE

本文是以不同时间的两次地下水质分析资料为基础,通过等比例类型抽样,分指数计算及两组判别分析,考虑各污染参数所起作用大小,研究岩溶地下水的污染趋势。

Based on the analyses groundwater quality of two groups of water samples collected at different times, the author has made equifractional type sampling, fractional index calculation, and discrimination analyses of the two groups of samples; and made a study on the pollution trend of groundwater in consideration of the harmful degree of individual pollution parameters.
