摘要
利用Kendall秩相关法判别辛安泉泉流量的变化趋势,建立1981—2006年的泉流量衰减方程,分析泉域内的降水规律和地下水开采量变化规律,并研究降水量变化和地下水开采对泉流量衰减的影响。结果表明:辛安泉泉流量在1980年以后有明显的衰减趋势,并服从负指数方程衰减;降水量变化和地下水开采是导致泉流量衰减的主要成因,地下水开采所导致的泉流衰减量占泉流衰减总量的83%。
The author of this paper tried to judge the change trend of the Xin＇an Spring flow by using Kendall rank correlation method, and set up an equation of Xin’ an Spring flow attenuation of the years from 1981 to 2006, analyzing the precipitation rule and the changing patterns of groundwater exploitation amount so as to study the influence of the variation of precipitation and groundwater exploitation on the spring flow attenuation.The results show that there has been an obvious attenuation trend in Xin＇an Spring since 1980, obeying a negative exponential decay equation; changes in precipitation and groundwater exploitation are the main reasons for the spring flow attenuation, and the spring flow attenuation resulted from groundwater exploitation accounts for 83% of the total flow attenuation.
