一、绪言时间序列分析是处理随机过程的一种数学方法。本文以贵州普定后寨和云南开远南洞两地下河流量为实例说明它在水文地质学中应用的前景。岩溶水的循环交替十分复杂,目前还不能精确地描述它的迳流特征,难以用确定的数学模 I. INTRODUCTION Time series analysis is a mathematical method of dealing with stochastic processes. In this paper, the case of Houzhai in Puding County of Guizhou Province and the underground river in South Cave of Kaiyuan County in Yunnan Province is described as an example to illustrate the prospect of its application in hydrogeology. The cycle of karst water alternation is very complicated. At present, it is not yet able to accurately describe its 迳 flow characteristics, making it difficult to determine the mathematical model
