摘要
针对地下水水质越来越受到人类活动影响的状况,本文以聊城东阿地下水源地水质评价为例,结合Matlab编程,引入时间序列分析方法,对水质参数监测值序列进行分析。分析结果表明:总硬度序列在2013年初发生跳跃且跳跃后呈上升趋势,序列无周期成分,说明2013年初存在导致总硬度含量上升的开采行为,但无周期性影响总硬度变化的开采活动。根据分析结果对地下水水质变化进行短期预测,预测结果显示,现状水质状况下若不加治理,总硬度将于2018年达到Ⅳ类水范畴。本文为地下水水质综合评价提供新的思路,也为地下水生态环境评价和地下水源地管理提供技术支撑。
In light of the situation that the influence of human activities on groundwater quality is more and more serious the paper took comprehensive water quality assessment of Dong-E groundwater source for example,combined with matlab and introduced time series analysis theory to analyze the series of monitoring value of water quality. The results show that total hardness monitoring series jumped in early 2013 and then kept rising. There was not periodic component. There was unreasonable and random mining actives which leaded to the increase of total hardness content in early 2013,but there was not periodical mining actives which affected the change of total hardness. In addition,this article also made short-term prediction based on the analysis. The result showed that if the management of water quality is not strengthed,the total hardness content will reach 451 mg / L in early 2018 which means Ⅳ-class water quality. The paper can offer new idea for the comprehensive assessment of groundwater quality and provide technical support for the assessment of groundwater ecological environment and management of groundwater source.
