摘　　要：地下水动态的短期变化特征已有很深入的研究 ,本文根据唐山地区 6口井 1 982年～2 0 0 1年 9月的水位动态变化月均值资料探讨地下水的长期变化特征。初步研究表明 ,从多年较大空间的地下水动态变化看 ,可视为较平衡的随机过程 ,存在着 1 0年左右的周期结构 ,这种周期结构与地质构造环境、水文地质环境、地理地貌、观测层位、补给和排泄条件以及观测井结构关系不密切 ,这种现象可能与复杂的全息天体运动有关 ,是一种多种周期的叠加 ,是一种合力作用 ,代表着区域应力场。the short-term variation characteristic of groundwater dynamics has been studied deeply.The long-term variation characteristic is studied with the monthly mean data of groundwater level variation recorded in the 6 wells in Tangshan region from 1982 to Sep.,2001.The results show that the dynamic variation of groundwater in many years and large space is a smooth random course,with a periodical structure about 10 years.The structure is not relevant closely to geological tectonic environment,hydrogeologic condition,geographical physiognomy,surveying layer,recharge and discharge condition and the distribution of surveying wells.This phenomenon may be relevant to complicated holographic celestial motion,which is a stack of many kinds period,or may be an action of resulting force representing the local stress field.
