摘　　要：为了解盐城市地下水水质的污染程度及空间分布,本文采集了59眼地下水监测井水样,采用主成分分析法和水质标识指数相结合的方法对其进行综合评价,并用ArcGIS插值分析法评价其空间分布。结果表明:该方法能很好地应用到盐城市地下水评价中,并且能识别不同区域的主要污染物和污染程度。可为我国地下水资源水质时空评估实现数字化转型奠定扎实基础。In order to understand the pollution degree and spatial distribution of groundwater quality in Yancheng City,59 groundwater samples were collected in this paper,which were comprehensively evaluated by principal component analysis and water quality identification index,and their spatial distribution was evaluated by ArcGIS interpolation analysis.The results show that this method can be well applied to groundwater assessment in Yancheng City,and can identify the main pollutants and pollution levels in different regions.It can lay a solid foundation for the digital transformation of the spatial and temporal assessment of groundwater resources and water quality in China.
