贵州省境内乌江干流水质现状分析

摘要

根据贵州省环境监测部门资料显示乌江已成为贵州省水污染程度最为严重的流域，突出的问题是总磷、氟化物超标。本文用最小二乘法模型和t检验方法对贵州省境内乌江干流2006—2013年水质状况进行分析，结果表明乌江干流总磷、氨氮、氟化物，高锰盐指数浓度变化趋式为“无趋势”，乌江干流水质稳定，并提出流域污染防治的对策和建议。%According to environmental monitoring data,the Wujiang River in Guizhou Province has become the most serious polluted river basin,and standard-exceeding of phosphorus and fluoride was the prominent problem. This paper used the least squares method and t test to analyze the water quality of Wujian River in Guizhou from 2006 to 2013 ,and result showed that water quality has sta-bilized,and environmental protection work has made positive progress in the Wujiang River Basin.
