济南泉水水化学动态特征分析

Hydro-chemical Dynamic Characteristic Analysis on Springs in Jinan City

摘要:

济南是山东省省会城市，以泉水而闻名，济南泉域位于济南市中部，为掌握济南泉水水质变化情况，根据多年监测的泉水水质资料，采用年度及年内对比方法，分析研究了泉水主要离子多年动态特征及年内变化，研究结果表明，从1984—2013年近30年间，济南泉水主要水质指标呈恶化趋势，主要驱动因素是CO2，SO2-4，Cl-离子含量的增长，其与当地燃煤量持续增长联系密切；而年内主要离子含量动态变化，属短期波动，与泉区排泄点周边的环境影响有关。

Abstract:

Jinan is the capital city of Shandong Province which is famous for springs. Jinan spring area locates in the middle of Jinan city. In order to grasp the changes of water quality of Jinan sprins, according to monitoring data in many years, by using annual and year comparison methods, dynamic characteristics and annual variation of major ions for many years, it is showed that, in the past 30 years from 1984 to 2013, main indexes of water quality of Jinan spring have a deteriorating trend. Main driving factors are the increasing content of CO2, SO2-4 and Cl-. It has close relation with continued growth and local coal consumption. Dynamic change of main ion contents belong to short-term fluctuations. It has close relation with surrounding environmental impacts surrounding spring area discharge points.
