研究了贵州遵义主城区23个地下水监测点2010—2012年（枯水期）水化学类型及水质的时空变化特征，用SPSS软件对水质测试结果进行统计，AquaChem软件对水化学类型进行分析，依据《生活饮用水卫生标准》（GB 5749—2006）并采用综合指数法评价了水质的状况及变化特征。结果表明：遵义主城区地下水化学类型主要为Ca－HCO3、Ca－SO4、Ca－Cl、Na－Cl型，时间变化对水化学类型变异性影响不显著；监测点中95.65％的地下水属于Ⅰ类水，其余属Ⅱ类水，水质较好；自2010—2012年，地下水监测点中17.4％的水质逐渐变差。

This study covers the hydrochemical types and spatial-temporal variations of 23 groundwater monito-ring sites in Honghuagang district and Huichuan district in Zunyi during 2010-2012 (dry seasons).SPSS soft-ware is adopted for the statistical analysis of the test of water quality,and AquaChem software for hydrochemical type analysis.Besides,sanitary standard for drinking water (GB 5749-2006)and synthetic index method are adopted to assess the water quality and variations.The results indicate that (1 )The principal hydrochemical types of groundwater in Honghuagang district and Huichuan district are Ca-HCO3 ,Ca-SO4 ,Ca-Cl and Na-Cl. (2 )Temporal variation does not have a significant impact on the variability of hydrochemical types. (3)95.65% groundwater in the monitoring sites is up to the GBI standard,and the rest is GBII,reflecting a good overall water quality.(4)The quality of 17.4% groundwater in the monitoring sites gradually degraded from 2010 to 2012.The research may serve as an important practical reference for local economic development and rational utilization of groundwater resources.
