摘要
///According to the Technical guideline for delineating source water protection areas (HJ/T338-2007), taking Jingquan karst water system in Teng Zhoujing, Shandong Province as research object, the authors stablished groundwater solute transport model with MT3DMS module in Visual Modflow, made a numerical simulation research on the condition of mining plan. Based on the simulation results and technical requirements, the authors delineated 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.
