利用频谱响应函数进行淄河流域地下水资源评价

THE USE OF FREQUENCY-SPECTRUM RESPONSE FUNCTION IN EVALUATION OF GROUNDWATER RESOURCES OF ZIHE AREA

本文采用系统方法,把淄河流域复杂的断裂岩溶含水系统划分为六个子系统。利用系统输入和输出的谱分析,认识系统特征,确定频谱响应函数,计算出系统参数,定量评价地下水资源。

The Zihe fractur-karst water-bearing system composed of four major faults and limestone blocks, which occupies an area of 1284 square kilometres, is a complex structure collecting and transporting groundwater 800 thousand m3/d. There are five large to medium- size groundwater source areas within the system connected with one another.The water-bearing system can be divided into six subsystems by means of systematology.Spatial and temporal variation of the spectrum function is used to analyze the connection characteristics of groundwater. On this basis, the recharge of groundwater under different recharge conditions can be determined by the frequency- spectrum response function. Similarly, the conversion between groundwater, surface water and meteoric water can also be determined. This method is applicable to the development and use of water resourses in large areas, originating from multiple water sources under complicated conditions.
