不同降深的稳定流抽水试验求参在梭罗树水源地地下水资源评价中的应用
Application of Steady Flow Pumping Tests with Different Drawdown Depths in Evaluation of Groundwater Resources in Thoreau Tree Water Source Area

岚山区是日照市重要的工业基地，经济发展及人口增加迅速，工业项目较多，而岚山区主要供水水源地为绣针河水源地，该水源地下游汾水–荻水水源地由于海水入侵已报废。现在只有中游大朱曹水源地能够利用，但因其水量小且已不能保障，供水不足已严重制约了岚山区的经济发展。而梭罗树水源地由于距岚山城区较近，该水源地淡水资源丰富，可作为城市生活用水，应急供水水源地。因此，文章在查明梭罗树水源地的水文地质条件后，预测了地下水动态变化，并利用2次不同降深的稳定流抽水试验计算有关水文地质参数，最终算出地下水允许开采量，这对水资源紧缺导致的岚山区经济可持续发展、居民饮用水等问题提供了数值化的建议，对于我国其他区域水资源的开采利用也具有一定的参考价值。
Lanshan District is an important industrial base of Rizhao City, with rapid economic development and population growth, and more industrial projects, while Lanshan District’s main water supply source is the Xiuzhen river source, which is the downstream Fenshui-Dishui water source, but has been abandoned due to seawater invasion. At present, only the middle reaches of the Dazhucao water source can be used, but because of its small water quantity and inability to guarantee, the shortage of water supply has seriously restricted the economic development of Lanshan District. As the water source of the Thoreau tree is close to Lanshan City, the water source is rich in freshwater resources, which can be used as urban living water and emergency water supply sources. So, after finding out the hydrogeological conditions of the water source of the Thoreau tree, this article initially predicts the variation of groundwater, and calculates the hydrogeology parameters by two steady flow pumping tests with different depths, finally gives the allowances production of groundwater. It not only provides the numerical value of advice to the shortage of water resources of Lanshan District about the problems of drinking water for residents and economic sustainable development, but also gives reference value to other areas of water resources exploitation in our country.
