摘　　要：地下水水质安全性评价是地下水资源保护的关键环节。为了阐明鲁中泰安-莱芜断陷盆地地下水水质安全性,本次研究系统评价研究区地下水水质现状、水质变化趋势和地下水污染风险,并以此为基础开展地下水污染预警分级,揭示地下水水质安全性。评价结果显示,研究区内地下水污染预警等级分为巨警、重警和中警3个级别。其中,巨警区占研究区总面积的21%,表明该区地下水水质极不安全;重警区占研究区总面积的26%,主要分布在巨警区外围约5km范围,地下水水质不安全;其他地区为中警区,占研究区总面积的53%,地下水水质临界安全。该研究可为鲁中地区泰安-莱芜断陷盆地地下水资源保护及合理开发利用提供有力支撑。Evaluation of groundwater quality safety is the key in groundwater resource protection.In order to clarify the safety of groundwater quality in Tai'an-Laiwu faulted basin in Luxi area,present condition of groundwater quality,the trend of groundwater quality change,and the risk of groundwater pollution in the study area have been evaluated comprehensively.Groundwater pollution warning grading has been carried out,and the safety of groundwater quality has been revealled.It is showed that the groundwater pollution warning level in the study area can be divided into three levels,they are huge alarm,heavy alarm and medium alarm.The huge alarm area accounts for 21% of the study area.It is indicated that the groundwater quality of this area is extremely unsafe.Heavy alarm area accounts for 26% of the study area,and mainly distributed in the outer area of about 5km of the huge alarm area with unsafe groundwater quality.The other areas are the medium alarm area,accounting for 53% of the study area,and the groundwater quality is critical safety.This study can provide strong support for the protection and rational exploitation of groundwater resources in Tai'an-Laiwu faulted basin in Luxi area.
