摘　　要：为了解日照水库水源地水质现状及变化趋势,该研究进行了多年的水质调查与监测,结合日照市环境监测站对日照水库例行监测点位的水质监测资料,在此基础上分析了当前的水质现状、水体的富营养化程度,探索其水质变化的趋势及动态规律。研究发现,日照水库水源地取水口区域水体富营养化水平呈现逐年增高的趋势,近年来富营养化水平达到轻度富营养化;COD浓度呈现逐年增高,其他有机化合物指标及非金属无机物指标等的变化趋势较为平稳,年际变化不明显。According to the routine monitoring data in recent three years by research group, and water quality moni- toring data about Rizhao reservoir monitoring point of Rizhao environmental monitoring station, based on analysis of current status of water quality and eutrophication, explore the dynamics of the water quality change trend. The study found that, the eutrophication level in the area of water intake of the water source in Rizhao reservoir shows an increasing trend year by year. In recent years, it has reached the light eutrophication. The COD is increas- ing year by year. The changes of other organic compounds and nonmetal inorganic indexes are relatively stable, and the inter annual variation is not obvious.
