基于经验正交函数法的趵突泉泉域地下水位动态分析

采用趵突泉泉域2006～2008年28个岩溶水位长测点的监测数据,通过相关性分析、经验正交函数分析法对地下水位动态的空间变化特征进行分析。结果表明:(1)趵突泉水位与其他长测点水位呈现显著和中度相关性,趵突泉泉域含水层整体连通性较好,岩溶发育规律较为一致;(2)研究区岩溶发育程度中部弱,两侧逐渐增强,且东部区域小于西部区域;(3)受地形对地下水位动态的影响,趵突泉泉域地下水位动态具有高度的一致性。刘长山-郎茂山-万灵山一线两侧地下水位动态呈相反的变化趋势,主要是由于岩溶弱发育带的影响。

Dynamic Analysis of Groundwater Level in Baotu Spring Region Based on EOF Method

Based on the monitoring data of 28 karst water level long-term measuring points in Baotuquan spring region from 2006 to 2008, the spatial variation characteristics of groundwater level dynamics were analyzed by correlation analysis and EOF analysis. The results show that the water level of the Baotuquan spring is significantly and moderately correlated with that of other long-term measuring points. The overall connectivity of the aquifer in the Baotuquan spring region is better, and the karst development law is relatively consistent. Influenced by the topography on the dynamics of the groundwater level, the groundwater level dynamics in the Baotuquan spring region are highly consistent. The groundwater level dynamics on the two sides of Liuchang Mountain -Langmao Mountain -Wanling Mountain showed opposite trends, mainly due to the influence of the karst weak development zone.
