摘　　要：通过对断层气Rn、CO_(2)、H_(2)逸出浓度详细勘测,沿断裂破碎带选取合适场址建设了10个固定观测站,形成覆盖郯庐断裂带江苏段的断层气连续观测站网,为监视郯庐断裂带江苏段活动情况、获取区域内构造地球化学场变化、捕捉地震前兆信息提供了重要的监测平台。根据数据变化特征和环境影响分析,在仪器运维和数据处理过程中排除外界干扰因素,提高监测数据质量。Based on the detailed investigation of the escaping concentration into fault gas(Rn,CO_(2),H_(2)),10 fixed observation stations have been built along the fracture zone to form a continuous network of fault gas observation stations covering the Jiangsu segment of Tanlu Fault,it provides an important monitoring platform for monitoring the activity of the Jiangsu segment of the tan-lu fault,capturing the changes of the tectonic geochemistry fields in the region and capturing the earthquake precursor information.According to the characteristics of data change and environmental impact analysis,external interference factors are excluded in the process of instrument operation and data processing to improve the quality of monitoring data.
