摘　　要：为研究内蒙古自治区多伦县地下水资源情况并保证多伦县地下水资源的可持续利用,采用水均衡法和开采系数法,对多伦县地下水资源进行评价和可采潜力分析。结果表明,研究区在均衡期总补给量为13768.72×10^(4)m^(3),总排泄量为13784.44×10^(4)m^(3),补排差为-15.72×10^(4)m^(3),即地下水资源在均衡期内呈现负均衡。但多年平均计算均衡差较小,说明多年来地下水处于天然状态,水位变化不大。通过可开采潜力分析,全区富水地段可开采资源量为2072.53×10^(4)m^(3),现状开采量为312.93×10^(4)m^(3),潜水开采潜力指数均大于1.2,说明多伦县地下水资源具有开采潜力,需要合理规划使用。In order to study the groundwater resource and ensure its sustainable utilization,the groundwater resource in Duolun County of Inner Mongolia was evaluated and the exploitable potential was analyzed through the water balance and exploitation coefficient methods,respectively.Results show that the total recharge of the studied area during the equilibrium period is 13768.72×10^(4)m^(3),the total excretion amount is 13784.44×10^(4)m^(3),and the difference is-15.72×10^(4)m^(3).This is to say that the groundwater resource is negative balance during the equilibrium period.However,the average equilibrium difference is small,which indicates that the groundwater is in a natural state and the water level has not changed much over the years.According to the analysis of exploitable potential,the exploitable resource in the water-rich section of the whole region is 2072.53×10^(4)m^(3),the current exploitation is 312.93×10^(4)m^(3),and the potential index of unconfined water exploitation is more than 1.2.It shows that the groundwater resource in Duolun County has potential for exploitation and needs to be rationally planned and used.
