柳林泉水化学特征及动态分析

柳林泉由100多个泉点组成,水质类型复杂、水温变化大。本文将其分为五个泉组,分别对各个泉组的水化学、水温及动态特征进行了分析,阐述了它们的分布规律及变化特征;对泉群流量的动态变化进行了相关分析、趋势分析和周期分析。结果表明: 自东向西,泉水水质逐渐变差,水温逐渐增高,泉水动态渐趋稳定。位于三川河南岸的泉点水温低,水质好;北岸的泉点水温高,水质差。泉流量的总体变化趋势呈指数曲线形式衰减,变化周期为16年,主要影响因素是降水入渗、河流渗漏及人工开采。 

ANALYSIS ON HYDROCHEMICAL CHARACTERISTICS AND REGIME OF LIULIN KARST SPRINGS

The Liulin spring consists of more than 100 springs, which can be divided into five groups. The hydrochemical types and water temperature of the springs are variable. In this paper, the hydrochemical characteristics, water temperature and regime of every group are analyzed, and the changing regulation is revealed, the relativity, tendency and periodicity of the springs flow are calculated. The results show that water quality becomes worse, the temperature gets higher, and regime becomes steadier from the east to the west. The temperature on the south bank of Sanchuan river is lower and the water quality is better than on the north. The general dynamic trend of the flow of the spring is reduced following an index law with a 16year period. The flow of the spring is impacted by infiltration of precipitation and leakage of river and exploitation.
