摘要
通过对辛安泉的泉水动态分析,获得了泉流量衰减变化的趋势。在岩溶水系统分析的基础上,采用数学相关模型对辛安泉的流量与大气降雨和人工开采进行了分析,研究了泉流量与大气降雨的延迟、滞后效应,分析认为20世纪70年代以来大气降雨的持续减少和80年代中后期人类的强烈活动,是造成泉流量衰减的主要原因。同时采用数学相关模型对辛安泉流量进行适时预测。
The trend of the spring discharge attenuation was given based on water dynamics in Xin＇ an Spring. On the basis of analyzing karst water system, the time delay and lag effect between spring discharge and precipitation was studied by use of mathematical model. The study shows that the continuous decrease of precipitation since the 1970s and the strong human activity at the middle-late 1980s were the important causes of the decline of spring discharge. Finally the flowrate of the Xin＇ an Spring was timely forecasted using mathematical model.
