摘　　要：雷州半岛地表水资源不足,火山岩及覆盖下的地下水资源十分丰富。近年来,随着地下水开采强度的不断加大,局部地区出现区域性水位降落漏斗,受人类影响的地表"污水"开始向地下倒灌,引发承压地下水水质恶化。该文以雷州半岛东部为研究区域,以不同地区不同层位地下水质量测试数据为基础,分析了火山岩孔洞裂隙水(Y11、Y12)、浅层水—微承压水(Y09、Y16、Y17、Y18、Y23、Y24)、中层承压水(Y07、Y25)和深层承压水(Y08、Y10)的地下水环境特征,然后对各层地下水主要离子含量、地下水化学类型、常规成分特征等因素进行分析,总结了研究区地下水环境特征。结果表明:研究区地下水环境整体较好,偏硅酸较高,适合生产生活用水,但近海岸近地表浅层水-微承压水受自然因素及人类活动影响较大,个别常规成分超标,极易影响中深层承压水。There are insufficient surface water resources,while groundwater resources under volcanic rock are abundant.Recent,with the increasing intensity of groundwater exploitation,regional drawdown funnel have appeared.It causes groundwater quality deterioration because of seepage of sewage influenced by human activities.As study area,based on sample test data of eastern Leizhou peninsula,the paper analyzes the features of underground water which contain volcanic pore fissure water(sample Y11,Y12),shallow phreatic water-confined water(sample Y09、Y16、Y17、Y18、Y23、Y24),medium confinedwater(sampleY07、Y25) and deep confined water(sample Y08、Y10).Then,it analyzes ain ion content,chemical type of groundwater and characteristics of conventional components of groundwater quality between the Aquifer.The characteristics of groundwater environment are summarized as follows:the groundwater environment as a whole is better in study area which contains more metasilicic acid for production and living water.But,shallow phreatic water-confined water which near the coast and surface is influenced by natural and human activities.It can influence the medium and deep confinedwater because of few indices beyond the standard.
