经频谱统计分析表明,奇村地下水中成分在一个水文年与多个水文年内发生的变化具有周期性特征,其中一年的准周期最为明显。它表明谱分析方法为研究水点动态变化规律提供了重要线索和途径。
The frequency spectrum analysis shows that the composition of groundwater in Qicun has periodic characteristics in one hydrological year and several hydrological years, and the quasi-period of one year is the most obvious. It shows that the method of spectral analysis provides important clues and ways to study the dynamic variation of water points.
