Abstract: Reservoir seismic monitoring network of Yalong river is the first reservoir seismic network designed and constructed basing on whole basin planning in Sichuan province. It is characterized by a large number of stations and complex terrain. Considering the terrain, environment, power supply mode, construction, investment, operation and maintenance of the station, the network is composed of 4G (3G) VPDN, satellite, ultrashort wave, wired fiber and the combination of the above communication modes to ensure the continuous and stable transmission of seismic data.

Key words: Yalong river network, reservoir seismic monitoring, complex terrain, communication networks

摘要： 雅砻江流域水库地震监测台网为四川省首个按全流域规划设计建设的水库地震专用台网，其台站数目众多且地形复杂，综合考虑台站所处地形、环境、供电方式、建设投资、后期运维等方面因素，采用了4G（3G）VPDN、卫星、超短波、有线光纤以及上述通信方式组合续传的方式组网，保证地震数据持续稳定传输。
