摘　　要：甘肃省受环境与经济发展影响下,水资源极度匮乏,针对最重要的地下水水资源,出现开采过度等现象,令甘肃省水资源的可持续性极大程度被限制,基于此提出加强应用地下水勘探开发技术,对甘肃省区域内地下水存在的问题予以及时、有效地管控,实现甘肃省地下水环境的有效保护。文章主要基于甘肃省2014-2021年的水资源利用统计数据,模拟分析了地下水开发利用与平均地下水储量空间变化情况,并以某区域为研究对象设置监测点,通过文章方法监测地下水水文环境。结果表明,全省地下水资源多年平均利用量占全省水资源利用总量的22%;研究区域的降水丰富,在水汽、地理影响下降水全年分配不均,区域内地下水储备最少的地方是党河洪积扇,党河灌区南北侧的地下水储备情况存在明显不同的主要因素是党河对灌区的开发作用。Gansu Province is affected by the environment and economic development,water resources are extremely scarce,for the most important groundwater water resources,there is over-exploitation and other phenomena,so that the sustainability of water resources in Gansu Province is greatly limited,based on this proposed to strengthen the application of groundwater exploration and development technology,Gansu Province regional groundwater problems to be timely and effective control,to achieve effective protection of the groundwater environment in Gansu Province.The article is mainly based on the water resources utilization statistics of Gansu Province from 2014 to 2021,simulating and analyzing the spatial variation of groundwater development and utilization and the average groundwater storage,and setting up monitoring points with a region as the research object to monitor the groundwater hydrological environment through the article method.The results show that the average multi-year utilization of groundwater resources in the province accounts for 22%of the total water resources utilized in the province;the study area is rich in precipitation,with uneven distribution of precipitation throughout the year under the influence of water vapour and geography;the lowest groundwater reserve in the region is in the floodplain fan of the Dang River;the main factor for the marked difference in groundwater reserves between the north and south sides of the Dang River irrigation area is the role of the Dang River in the development of the irrigation area.
