对华北地区40多年来完成的50条深地震测深剖面的数据进行系统的分类和整理,利用分层插值并拼合的数值化方法对二维速度等值线图进行数字化,建立基于经纬度信息的二维速度结构模型和主要界面深度模型.基于MySQL数据库管理系统,实现了web浏览器对模型数据的快速查询功能.华北深地震测深成果库的建设为深地震测深成果的转化提供条件,为地球科学相关领域提供精细的地壳模型参考,也提高了该项数据资料服务于社会的水平.地壳二维速度模型和主要界面深度模型数据为深入研究华北地区地震发震构造、华北克拉通破坏等科学问题提供最基础的资料.
The data of 50 deep seismic sounding profiles completed in more than 40 years in North China are systematically classified and sorted. The two-dimensional velocity contour map is digitized by using the method of hierarchical interpolation and concatenation, and the data based on latitude and longitude information 2D velocity structure model and the main interface depth model.According to the MySQL database management system, the web browser can quickly query the model data.The construction of the deep seismic sounding database in North China provides the conditions for the deep seismic sounding conversion, Which provides a reference for the geosciences related to the fine crustal model and improves the level of data service to the society.DESCRIPTIONS OF CRUSTAL TWO-DIMENSIONAL SPEED MODEL AND MAIN INTERFACE DEEP MODELS In order to further study the seismogenic structure of the North China area and the damage of the North China Craton And other scientific issues provide the most basic information.
