摘要
为研究正蓝旗地区的地下水资源情况,利用正蓝旗气象站1960-2013年气象资料和多年地下水长期观测数据,通过对研究区水量补给、径流和排泄的计算,并基于水均衡法和开采系数法,对研究区进行了地下水资源评价和可开采潜力分析。经计算知,研究区多年平均可开采资源量为25 800.23×10^4m^3/a,多年平均总补给量37 797.44×10^4m^3/a,总排泄量为38 018.96×10^4m^3/a。该区地下水资源整体处于负均衡状态,但多年计算均衡差较小,地下水处于天然状态,水位变化不大。通过可开采潜力分析发现,各富水地段开采潜力指数较大,拥有开采潜力,可合理规划使用地下水资源。
The meteorological data of the Zhenglan Banner weather station from 1960 to 2013 and the observation data of groundwater for many years were used to study the condition of groundwater resources in the Zhenglan Banner area.The water supply,runoff and discharge in the study area were calculated based on the water balance and mining coefficient method to evaluate the groundwater resources and the exploitable potential of the area.The results showed that the average annual exploitable resource of the region was 25 800.23×10^4m^3/a,the average annual total recharge was 37 797.44×10^4m^3/a,and the total excretion was 38018.96×10^4m^3/a.It was also revealed that groundwater resources in the region were in a negative equilibrium state for many years,but the equilibrium difference was small,indicating that the groundwater was in a natural state and the water level did not change much for many years.The analysis of exploitable potential demonstrated that the exploration potential index of each water-rich section in the region was larger and the area had higher mining potential,suggesting the groundwater resources should be planned and used rationally in the area.
