Abstract: The reservoir earthquake monitoring system for Yalong river basin is the first real-time reservoir earthquake monitoring system in Sichuan province, which is based on integrated watershed design, cascade development and multiple sub-networks. The system has the characteristics of wide monitoring scope, high complexity of network integration, stable system operation and real-time sharing of monitoring data. This paper outlines the general situation of the system, the layout of stations, the design concept and construction of communication network as well as the central station for earthquake monitoring
network, and expounds the characteristics of the earthquake monitoring system for Yalong river basin reservoirs combined with years' operation practice.

Key words: basin monitoring system, earthquake monitoring, real-time monitoring, system construction

摘要： 雅砻江流域水库地震监测系统是四川省首个流域化统筹设计、梯级建设、一个中心，多个子网的实时水库地震监测系统，该系统具有监测范围广、组网集成复杂度高、系统运行稳定、监测成果实时共享等特点。笔者概述了系统概况、台站布置、通信组网和台网中心的设计理念和建设情况，并结合多年运行实践阐述了雅砻江流域化水库地震监测系统的特点及监测运行情况。
