摘要
利用章丘市2005-2006年自动观测降水和泉水地下水位资料,绘制动态变化图进行直观分析,计算相关系数进行相关性量化分析,最终揭示降水对泉水地下水位变化的影响程度及两者之间的密切联系。结果表明,〈10 mm和10-30 mm的降水与泉水地下水位变化的相关系数较小,对泉水水位回升影响不大;〉30 mm降水与地下水位变化相关系数大,对泉水水位回升作用显著。
Using the data of rainfall and groundwater level of spring water through automatic observation in Zhangqiu during 2005-2006,the dynamic change map was developed for intuitive analysis.The correlation coefficient was calculated for correlation quantitative analysis.At last,the influence degree of rainfall on the groundwater level of spring water and the close correlation between the two were revealed.The results showed that the rainfall with the amount of less than 10 mm and 10-30 mm had smaller correlation coefficient with the groundwater level changes of spring water and had not great influences on water level rise.The rainfall with the amount of more than 30 mm had great correlation coefficient with the groundwater level changes and had significant influences on the water level rise of spring water.
