摘要
介绍浙江省数字地震台网基本情况,阐述功率谱分析的计算方法,并对各台站地动噪声计算分析。结果表明,各台站的台址环境和观测仪器的性能基本优良,能够适应宽频带地震观测要求。部分台址观测条件由于受到人为因素的影响,可以有针对性地对部分台站进行环境改造,为地震监测预报创造条件。
We introduce the basic condition at Zhejiang Digital Seismic Network,and state the computation manner of power spectrum analysis.We also computate and analyze the ground motion noise of each station.It shows that the environment of each station site and performance of instruments are basically good,and can meet the requirement of broadband seismic observation. Parts of station's observation constructions has been affected by artifical factors.It can be improved with environmental reconstruction and build better construction for earthquake monitoring and forecast.
