【摘要】 针对娘子关泉域降水补给的时滞问题展开研究,根据泉域水文地质条件的灰色系统特征,提出了带有时滞的灰色关联分析模型,并运用该模型对泉域不同区域的降水量与泉水流量进行了时滞分析,结果表明,娘子关泉域不同区域的降水对娘子关泉的补给时滞存在差异,位于中间主流带的阳泉市、平定、盂县、昔阳与和顺的降水时滞为2年;位于西南、西北径流区边缘的寿阳和左权的降水时滞为4年。更多还原

【Abstract】 Niangziguan Spring, the largest karst springs in North China, is located in Mianhe Valley to the east of Yangquan City, Shanxi Province. From 1958 to 1996, the average discharge of Niangziguan Spring is 10.93m3/s. The area of the spring basin is 7217km2. Precipitation is the main source that supplies the karst water. The relation between precipitation and spring discharge is important for the exploitation and conservation of karst water. It is focused on the problem of the timelag from the precipitation to the supply of the Niangziguan Spring in this paper. Based on the greysystem characteristics of the springbasin’s hydrogeologic conditions, timelagexisting grey incidence analysis model is put forth. By using the model, the timelag is analyzed. It is proved that the precipitation in different regions has different timelag. The timelag of the major groundwater runoff region in the middle of the spring basin, including Yangquan City, Pingding County, Yuxian County, Xiyang County and Heshun County, is 2 years. The timelag of the weak groundwater runoff region in the southwest and northwest of the spring basin, including Shouyang County and Zuoquan County, is 4 years.更多还原
