摘　　要：通过对ArcGIS API for JavaScript、ArcGIS Server 和地理信息数据库等关键技术的研究,开发基于ArcGIS API for JavaScript 的地震人口热力图快速出图程序。利用移动互联网人口位置大数据和ArcGIS API for JavaScript 的符号渲染、图形绘制、查询分析、自动打印等功能,实现Web 端震中周边不同范围人口的秒级热力渲染、统计展示和自动出图,在河北永清4.3 级等地震事件中通过地震信息播报机器人及时产出,取得较好的应急实效。By researching the key technologies of ArcGIS Server, ArcGIS API for JavaScript and Geodatabase, the program of quick mapping for seismic population thermal map based on ArcGIS API for JavaScript is developed. By using big data of mobile internet population location and symbol render, graphics, query, automatic print of ArcGIS API for JavaScript, the program has realized the heat map renderer, statistics and automatic drawing of population in different ranges around epicenter on web within several seconds. The seismic population thermal maps were published through earthquake information broadcast robot in the earthquake events such as the Yongqing M 4.3 earthquake in Hebei and good emergency results are achieved.
