| 摘 要： | 本文概述了南北地震带南段的水文地质条件和水文地球化学特征，并编绘了B、F、Li、Sr等微量元素的异常图，分析了水文地球化学与地震的关系。认为(1)构造对地震、地下热水和微量元素的高值区均具有控制作用，它们在空间分布上具有较明显的一致性；(2)高中温热水区(尤其是高中温热泉密集带)，常常是地震活动的强烈区，但强震区不一定有高中温热泉密集；(3)在地震孕育过程中，温泉和热水井中的水温、流量和水化学成分均可发生变化。温泉热水中的水化学成分，特别是微量元素变化是地震预报的前兆信息之一。

| Abstract: | This paper outlines hydrogeologic condition and hydro-geochemical feature in the Southern part of North-South Earthquake Belt in China and maps abnormal map of microelements of B,F,Li and Sr. At the same time,the relationship between hydro-geochemical feature and earthquake is analyzed. The research results indicates:(1) Earthquake,geothermal heat and microelement abnormal areas are controlled by tectonic.Their distributions in space are obviously same.(2) High-middle temperature water areas,especially the areas of high-middle heat spring,are always the strong regions of earthquake activity.But the strong earthquake area does not always occur in high-middle heat spring.(3) During the process of earthquake formation water temperature,flow quantity and hydro-geochemical component in geothermal wells and hot springs may be changed. The change of hydro-chemical components,especially microelement in hot springs may be one of information to forecast earthquake. |
