摘要

采用流动采样、定点观测分析方法,对滇西北地区部分典型活动断裂带上天然出露的温泉,进行水汞背景值(本底值)调查和观测研究,得出各点位温泉中水汞的正常变化范围、空间分布特征,以及与活动构造的关系,用于滇西北地区地震短临跟踪加密观测,以及强震现场周围的前兆异常监视工作。
The author studied the background value of Hg in hot water through irregularly gathering and anlyzing water samples from hot springs which natively distributed along active faults in northwestern Yunnan Province.The results mainly included the mean and the variance of observing data as well as the relationship between spatial distribution of Hg and characteristics of active faults.This research would be an useful background knowledge to judge the observing data are normal or anomalous during dense precursory monitoring for short-term and imminent earthquake prediction in this area in future.
