摘　　要：在腾冲火山地区开展地球化学综合观测是监测火山活动重要而有效的方法之一。通过火山地区地下流体观测 ,可记录地壳应力应变、地温变化、气体及离子组份的释放量、释放方式和释放成分 ,进而可了解地壳内部岩浆活动与通道开启状况 ,为火山活动、构造活动、地震活动提供信息 ,开展监测、预测、对策研究。现腾冲火山地化综合观测站经科学论证、选井、选址、选项 ,已完成基建及仪器安装等建设 ,基本测项已投入正常观测。Performance of geochemical synthetic observation in Tengchong is one of effective methods. The observations of underground fluid can record stress and strain in crust, variation of geo-temperature, releasing of gas and concentration, releasing mode and component. Further, we can understand magma activity and channel opening condition, which can provide information for volcano activity, tectonic and seismicity, perform forecast, monitoring and countermeasure studying. The construction of geochemical observatory has finished proof, well selection, site selection, term selection and settlement of instruments, and put into operation.
