摘要
河流水质状况的好坏是自然环境优劣的一个主要因素,以前对水环境的评价只局限在某些水质指标的化验成果来判断河流的水质类别,零散单一,且不直观。采用曲线图形判断和数理统计的偏差分析,可以直观地反应河流水质状况的历史变化过程和即时效应情况,可实用方便地对河流水质状况进行监控和分析。
The water quality is a major factor to assess natural environment quality. The previous assessment method is very simple, which is only limited to judge water quality categories of river flow according to the test results of some water quality indexes. The curve method and mathematical statistic deviation analysis can directly manifest the course of historical change and real-time reaction. In this way, it is convenient to monitor and analyze the river water quality.
