Google Earth是Google公司发布的当前非常流行的一款三维虚拟地球软件,已在许多行业得到了广泛应用.采用传统方法研究地壳形变时,对点、线、面的分析一般是基于地理信息系统软件,通常在三维功能上较为欠缺,而引入Google Earth软件可较好地进行三维地形等要素的显示.介绍Google Earth的KML语言格式、功能与特点,采用Visual Basic编程,充分利用KML功能,将中国大陆的地震、GPS观测站及其运动矢量等要素很好地展示在三维地球上,直观地显示出地震的地理分布和中国大陆的地壳运动状况,取得较好的效果.%Google Earth is a popular three dimensional virtual earth software release by Google. It has applied in many domains, such as pipeline engineering, geography teaching, geology and earthquakes. Usually, the crustal deformation impressions by the geography information system software are researched. Shortage for their three dimensional functions,the Google Earth to accomplish them is introduced. This research briefly introduce the language formations, functions and characters of KML ( Keyhole Markup Language) language of Google Earth. Using the Visual Basic and according to the CNSS formation description of earthquake catalogs, a good expression of earthquake on Google Earth is gived with full utility the point, line and polygon of KML. It more directly shows the geographic distributions of earthquake, at the same time, we overlap the GPS velocity arrows with different color, it is a optical display result with the crustal movement and earthquake location on the three dimensional image of Google Earth.
