我国水环境污染现状与化学计量应用分析

水环境的质量关系到个人的健康和国家的可持续发展,是环境领域研究和监测的重要组成部分。数据质量控制是水环境研究中的一个重要问题,其重要性早已受到重视。数理统计可对不同处理间的差异程度以及假设条件进行分析,但无法替代保证数据准确性的计量学方法。文章对我国目前水环境状况及研究进展进行分析,并对环境监测、评价和预警体系中核心内容的数据质量和溯源体系以及测试仪器性能评价进行介绍,从学科发展角度探讨水环境监测和治理对量值溯源和化学计量的需求,为水环境数据质量控制提供计量支持。水环境的发展要求从更大范围的时间和空间尺度对环境问题进行分析,依赖化学计量学手段提供的溯源支持和有效性证明。

Proceeding and Analysis of Water Environment and Chemical Metrology Application

Water environment quality may play important role,as one important part of environment study and monitoring,in people's health and the sustainable development of a country.It is well known that quality Control of data is an important problem for environment study.Statistics can compare the difference and test the hypothetical condition.However,statistics can not stand for the effect of metrology which focus on the accuracy and traceability of data.Proceeding and development of water environment of China wer...
