区域地震速度模型分析与应用系统的实现

为有效地管理地震速度数据，方便灵活地进行模型分析，并直观地以模型的形式反映地震速度在各个区域内的分布情况，“区域地震速度模型分析与应用系统”基于MapGIS-TDE平台的三维建模技术，应用属性建模和结构建模两种方式，使用插件技术完成地震速度数据的录入、管理、输出和三维可视化分析功能，该系统提供了方便快捷的地震速度模型（包括层速度模型和叠加速度模型）的分析功能和高效的地震速度数据管理功能。

Implementation of analysis and application system for regional seismic velocity model

In order to manage seismic velocity data effectively and analyze the model facilely,at the same time,reflect the distribution of seismic velocity in all regions in the form of model intuitively.This paper designs and implements the analysis and application system for regional seismic velocity model which is based on the Windows operating system takes project as the database unit.Based on the mature three-dimensional modeling techniques of MapGIS-TDE platform,by the ways of property modeling and structure modeling, this paper uses plug-in technology for the completion of the entry, management, output and three-dimensional visualization analysis about the seismic velocity data.The system has been proved convenient in analyzing the model of seismic velocity and efficient in managing seismic velocity data.
