摘要

城市供水水源地在促进城市的发展,解决城市水资源供需矛盾等方面发挥着重要的作用。目前山东省主要城市重点供水水源地共25处,采用水质综合指数法对2016年的水质状况进行评价,并根据2007～2016年期间水源地水质指标和水质指数WQI值分别进行了季节性Kendall检验和趋势线直观分析,通过两种评价结果的对比综合分析山东省水源地水质变化趋势,结果表明,山东省水源地现状水质较好。采用两种检验方法所得出的水源地水质变化趋势基本一致,避免了采用单一分析方法进行趋势分析的的局限性,互为补充和验证,分析结论合理可靠。
        The source of urban water supply plays an important role in promoting the development of cities and solving the contradiction between supply and demand of water resources in cities. At present, there are 25 main water supply sources in main cities of Shandong province. The water quality of these sources in 2016 is evaluated by the comprehensive water quality index method.The seasonal Kendall test and the trend line analysis are carried out according to the water quality indicators and the water quality index WQI values of the 2007～2016 years, and the difference between two evaluation results is given.The trend of water quality in Shandong is also analyzed.The results show that the water quality of the water sources in Shandong is good.The water quality change trend of the water source area obtained by the two methods is similar.Using the two methods avoids the limitation of the single analysis method and they can complement and validate each other,making the evaluation reasonable and reliable.
