摘要：采用综合评价法进行诏安县宫口半岛地下水质量评价。在检测的松散岩类孔隙水70组样
品中，Ⅰ类水2组，Ⅱ类水7组，Ⅲ类水0组，Ⅳ类水41组，Ⅴ类20组，Ⅳ类-Ⅴ类地下水占61组，
超标率达 87.14%。风化残积孔隙裂隙水质量类别为较差-极差(Ⅳ类-Ⅴ类)占 5 组，超标率达
55.65%。基岩裂隙水水质总体较差，共检测 4 组，其中Ⅳ类水 3 组，Ⅴ类 1 组，主要超标因子为
Cl 、NO 、矿化度。不同含水岩组地下水受人为影响较大，各含水层皆受到“三氮”污染，其来源

Abstract:The Environmental quality assessment was carried out for groundwater in Gongkou Peninsula of Zhao’
an County. 70 samples of pore water in loose rock zone of the quaternary totally were detected. The groundwater sam⁃
ples of quality evaluation from Ⅰto Ⅴ grade were 2,7,0,41and 20 respectively. The over standard rate of Ⅳ and Ⅴ
grade was 87.14%. Water sample quantity of Ⅳ and Ⅴ quality grade of pore-fracture water in weathered layer was 5,
and the over standard rate was up to55.65%. On the whole, the water quality of bedrock fissure water was poor with 3
- -
samples of Ⅳ grade and 1 sample of Ⅴ grade. The main factors influencing the groundwater quality were Cl , NO ,
3
and salinity respectively. Groundwater quality in various aquifers was dramatically affected by people activities. Each
aquifer was polluted by three nitrogen which was from domestic wastewater, domestic waste and random discharged
aquaculture wastewater.
