摘　　要：根据2007年2月1日实施的《饮用水水源保护区划分技术规范》(HJ/T338-2007),以滕州荆泉岩溶水系统为研究对象,采用Visual Modflow中的MT3DMS模块建立地下水溶质运移模型,进行了水源地规划开采状况下的数值模拟研究。依据模拟结果和有关技术要求分别将污染物运移100d和1000d恰好到达水源地中心的捕获区划分为一级保护区、二级保护区,二级保护区以外的地下水补给区划分为准保护区。水源保护区的划分为保护地下水水质、保障城市供水安全提供了决策依据。According to the Technical guideline for delineating source water protection areas （ HJ/T338-2007 ）, take Jingquan karst water system in Teng Zhoujing, Shandong Province as research object, we establish groundwater solute transport model with MT3DMS module in Visual Modflow, make a numerical simulation research on the condition of mining plan. Base on the simulation results and technical requirements, we delineate the first-class protection area and the second-class protection area separately： the captive section which pollutant just arrived at the groundwater wellfield center by transporting 100 d and 1 000 d. And the ground water supply district that outside the second-class protection area is delineated the quasi-protection area. The water source protectorate division provide the policy-making basis for protect the ground water quality, safeguard the urban water supply safely.
