摘要
通过收集整理10年的地表水环境监测资料,综合分析了钱塘江下游干流新安江和富春江区域的水质变化规律。应用斯毕曼秩次相关性检验、相关分析和方差分析,研究了两江流域内水质变化的趋势与联系,结果表明,两江流域内水质总体仍处于低风险水平,仅在部分区段和时段内出现个别项目超标。两江流域水质的主要胁迫因子均与社会经济活动有关,但尚未超出流域内环境容量容许范围,总体水质仍能满足功能区要求。说明通过合理控制污染排放,完全可能实现两江流域社会经济与环境保护协调发展。
In order to analyze the water pattern of Fu-chun River and Xinan River area, two downstream of Qiantang River,the water quality monitoring data in ten years of this area was collected. By application of Spearman correlation analysis, correlation analysis and analysis of variance, the trend and relationship of water quality in this area were researched. Results indicated that the water quality of this area is keeping in low risk level. Some major stress factors on water quality are concerned to activity of society and economy, but these stresses are still in the range of environment content. So it is possible to keep the balance between socio-economic development and environmental protection in this area.
