| 摘 要： | 文中重点研究了基于地震现场能够获取的离散的地震灾情点信息进行灾情的总体分析和模拟。依靠灾情速报人员或相关人员上报的地震现场灾情点信息,运用泰森多边形和GIS空间分析方法对离散点进行面插值分析和边界修正处理,形成适合计算离散灾情采样点的模型和算法,并借助GIS技术和WebService技术实现该模型和算法,建立相应的试验系统。该模型和系统能够随着灾情收集点的变化进行动态的分析模拟,从而能够在一定程度上及时快速地反映并确定地震灾情的基本分布情况,为地震救灾指挥提供相对确切的灾情分布信息。文中以汶川地震部分数据为例进行分析,结果基本与实际灾情吻合。选取的数据为73条有效短信,这些短信是从截至5月12日24:00收到的600余条灾情上报数据短信中分析提取出来的

| Abstract: | Earthquake always happens in an instantaneous and abrupt way,and the aftermath of an earthquake is difficult to be expected.The earthquake fieldwork teams are very difficult to arrive at the earthquake-stricken site and to provide the relevant information in 2 hours after an earthquake breaks out.We usually call this period of time as the "black-box" period of earthquake.The MS 8.0 Wenchuan earthquake caused extremely high damage and wide influencing range,and how to quickly obtain the information on the di... |
