摘要
济南泉水源自区域降水,随降水的丰枯而变化。通过对济南泉群涌水量与区域降水的回归分析,得出济南泉水与济南东南部岩溶漏水山区的降水关联程度最为密切,说明济南泉水的主要补给区可能是济南泉群东南部岩溶漏水山区。根据区域内已有的降水和涌水量,预测预报济南泉群第二年枯水期应有的自然涌水量,为济南保泉供水提供有益的探讨。
The source of Ji'nan Springs comes from precipitation that varies due to the rich and poor of precipitation periodically.By means of regression analysis of Ji'nan Springs output and precipitation in the region,it is found that Ji'nan Springs has closest connection with precipitation in the karst mountainous area in the southeast of Ji'nan City.Thus,it is concluded that karst mountainous area in the southeast of Ji'nan is the main source feed the Ji'nan Springs.According to the observed data of precipitation and output of springs,the natural output of springs in the dry period of next year shall be forecasted,which is of great help for securing supply of Ji'nan spring water.
