摘要
为实现日照市付疃河流域地下水资源合理开发及持续利用,本文在采用均衡法计算傅疃河流域地下水资源量的基础上,运用GMS软件模拟预测3种开采方案下地下水资源水位变化情势。均衡法计算结果显示:综合考虑地下水补给量、排泄量后付疃河流域地下水资源总补给量(277,740.7 m3/d)≈总排泄量(260,893.29 m3/d),其出孔隙水的开采潜力指数为1.04及裂隙水的开采潜力指数为1.18,即该区域地下水资源总体处于采补平衡状态,全区地下水自然循环基本保持较好的态势。进而在此基础上,通过GMS (Groundwater Modeling System)软件模拟:(1) 现状开采条件下1年、5年、10年、20年后的地下水位;(2) 飞机场水场和河套水厂开采地下水后1年、5年、10年、20年后的地下水位;(3) 崮河汇入傅疃河处设置拦河坝后运行1年、5年、10年、20年的地下水位变化情势。模拟结果显示三种方案下,该区域地下水资源总补给量大于总排泄量。这为该区地下水资源的合理开发和利用提供量化的数据支持,具有重要的实践应用价值。
In order to realize the reasonable development and sustainable utilization of groundwater re-sources in Futuan River Basin of Rizhao City, GMS software is used to simulate the groundwater level changes under three mining schemes based on the calculation of groundwater resources in Futuan River Basin by using equilibrium method. The results of equilibrium method show that the total recharge of groundwater resources (277,740.7 m3/d) is approximately equal to the total discharge (260,893.29 m3/d) after considering the groundwater recharge and discharge. The exploitation potential index of pore water and fissure water is 1.04 and 1.18 respectively, which means that the groundwater resources in this area are in the balance state of exploitation and supplement, and the natural circulation of groundwater in the whole area basically keeps a good situation. On this basis, the GMS software is used to simulate: (1) The groundwater level under the current mining conditions after 1 year, 5 years, 10 years and 20 years;(2) The groundwater level after 1 year, 5 years, 10 years and 20 years after the airport water field and Hetao water plant exploit the groundwater;(3) The groundwater level changes under the conditions of 1 year, 5 years, 10 years and 20 years after the dam is set at the place where the Gu river flows into the Futun river. The simulation results show that the total recharge of groundwater resources is greater than the total discharge under the three schemes. It provides quantitative data support for the rational development and utilization of groundwater resources in this area, and has important practical application value.
