摘　　要：在深汕特别合作区水文地质调查的基础上,结合水化学分析,研究区内地下水类型、含水层分布、水化学特征,并对地下水质量进行评价。区内地下水类型为松散岩类孔隙水和基岩裂隙水,含水岩组包含各时代地层,含水岩组的富水性差异较大,大气降水为主要补给来源,通过河流排泄;地下水类型划分HCO3、HCO3·C1、C1·HCO3、C14种类型;水质总体较差,区内地下水资源按功能规划分为4个区,为深汕特别合作区的地下水资源开发提供建议。On the basis of hydrogeological investigation in Shenzhen-Shanwei Special Cooperation Zone,combined with hydrochemical analysis,the groundwater types,aquifer distribution,and hydrochemical characteristics in the area are studied,and the groundwater quality is evaluated.The groundwater types in the area are loose rock pore water and bedrock fissure water,the water-bearing rock groups contain strata of various ages,and the water yield properties vary greatly.Atmospheric precipitation is the main source of supply and is discharged through rivers.The classification of groundwater types includes four types of HCO3,HCO3·C1,C1·HCO3,and C1.The water quality is generally poor,and the groundwater resources in the area are divided into four zones according to functional planning,which provides suggestions for the development of groundwater resources in the cooperation zone.
