摘　　要：在黑龙江省北部岛状冻土带上,使用WDJD-1多功能数字直流激电仪试验性找水,利用观测参数半衰时th、极化率ηs、衰减度D、视电阻率ρs等来推断含水层位、设计井深、估算涌水量、优选井位,研究结果表明该方法有一定的实用性。On island tundra of Heilongjiang province ,we used WDJD -1 to hunt water .By means of the information of observed parameters as half decay time t_h,polarization ηs,decay factor D,apparent resistivity ρ_s.We determine water-bearing layer, devise the depth of well,estimate water gushing volume,choose the best location of well.The result made know the method has definite practicability.
