| 摘 要： | 通过关键词共现分析方法，对深地震测深技术在国内的发展及其应用现状进行研究。结果表明，深地震测深资料处理以二维动力学射线追踪的正反演方法为主，三维地壳结构模型的构建方法则以改进的克里金插值方法为主；深地震测深可用于揭示孕震构造环境，但对区域地壳结构与地震发生规律和活动性的总结较少；在地震测深成果方面，包括地壳结构类型和地壳厚度等，与地热、金属以及油气矿产资源的形成密切相关，但是目前尚未形成能够服务于矿产资源勘查的成果库和数据产品；海洋深部探测是目前深地震测深方法应用的热点，应当加强海陆联合地震观测，充分发挥两种观测模式的优势。

| Abstract: | Through the method of keywords co-occurrence analysis, we carry out an analysis of the development and application status of deep seismic sounding (DSS) technology in China. The results show that the data processing of deep seismic sounding is mainly based on the forward modeling method of 2D dynamic ray tracing, while the 3D crustal model is mainly constructed by Kriging interpolation. DSS method can reveal the seismogenic tectonic, but rarely summarizes the relationship between the regional crustal structure and earthquake distribution and activities. In terms of seismic sounding results, including the type of crustal structure and crustal thickness, are closely related to the formation of geothermal, metal, and oil and gas mineral resources. However, there are no available DSS database or data products for mineral resources exploration. Ocean deep exploration has become a focused area in the application of DSS method. The onshore and offshore deep seismic experiment should be strengthened to give full play to the advantages of the two different observation modes. |
