塔里木河干流区地方性氟病区水化学成分的多元分析

Multi-variable Analysis of Chemical Components in Water in Endemic Fluorosis Region of Tarim River Mainstream Basin

本文运用相关分析、回归分析及Ｒ－型系统聚类分析等方法，研究了塔里木河干流地区地方性氟中毒病区内，氟斑牙患病率与饮用水中氟元素及其它化学成分的定量关系，并建立了生活饮用水中氟元素与其它化学成分的回归计算模型．揭示了区域内氟斑牙治病的主导因素以及水体中各化学成分和化学性质指标间的相互关系，为探求饮用水型地方住氟中毒的病因提供了科学依据。

This paper mainly studied the relationship between the ratio of suffering from dental fluorosis and chemical components in drinking-water in endemic fluorosis region of Tarim River mainstream basin by means ofcorrelation analysis, regression analysis and R-cluster analysis.
