全国水温台网井水温度2008年动态及其汶川地震前后的异常变化

在全面收集与系统分析全国水温台网近300口观测井2008年动态的基础上，梳理出井水温的正常年动态与固体潮，并进一步识别与分析2008-05-12汶川MS8.0地震震前、震时及震后的异常变化；归纳出全国井水温动态的正常年动态类型、特征及水温潮汐的基本特征，识别出汶川地震前14口井出现的异常，并分析该异常的形态与时空分布特征；分析125口井的同震响应与震后变化特征，进一步论证利用井水温动态监测地震前兆的可能性与存在的问题，提出把现有的水温观测网进一步改造与升级、开拓地壳热动态与地震活动关系观测与研究的创新思路。

Dynamics of Water Temperature in China Geothermal Network: Anomalous Changes before and after Wenchuan MS8.0 Earthquake in 2008

Based on comprehensive collection and systematical analysis of China water temperature observatory dynamics in 2008 within nearly 300 wells, we first ascertain the relationship between water temperature dynamics and earth tide and analyze anomalous change before and after the May 12th Wenchuan MS8.0 earthquake. Second, we clear the normal drill water temperature dynamics in year time and the basic features of temperature tidal effects, determining that there are 14 abnormal wells before earthquake. We summarize anomaly patterns and the spatial-temporal characteristics, analyzing coseismic corresponding characteristics of 125 wells. Finally, we further demonstrate possibilities and problems in water temperature and seismic monitoring, and come up with upgrading the hydrothermal observation network to a geothermal observation network, to explore the new ideas in the study of the relationship between crust thermal and seismic activities.
