基于主成分分析法对开阳县岩溶地下水水质的评价

The evaluation of karst groundwater quality based on principal component analysis in Kaiyang

本文采用主成分分析法,对贵州省开阳县的9个地下暗河出口及岩溶泉的水质进行综合分析,选取其中具有代表性的13个实测数据进行定量化评价。结果表明,除城关镇石头村由于受到Fe、Na+等污染导致水质较差以外,该地区地下水水质总体都较好,与实际情况相符合,评价结果能为水资源合理开发利用和水污染的综合防治提供参考。

This paper analysed the water quality of nine underground rivers＆#39;exports and karst springs comprehensively in Kaiyang of Guizhou province with the method of Principal Component Analysis. 13 representative measured data were selected to make the evaluation. The results showed that the groundwater quality was generally fine in this area ,except one village,namely Shitou village of Chengguan Town,where the water quality was poor due to the contamination of iron and Na＋.
