摘要
通过样本数据建模,改进传统的人口分布模型中"行政区划的统计样本"与"网格单元"尺度不一致的问题,并将湖北省人口数据空间化结果应用于巴东Ms5.1地震灾情盲估。结果表明,人口数据空间化方法可以较好地反映人口分布情况,用该数据得到的灾情盲估结果有较高的可信度。
The method of population gird data spatialization base on sample instend of region＇ s statistical data and rapid loss assessment in Badong earthquake was introduced in the paper. The results show that the method reflects actual population distributio, and the result of assessment is credible. The method the can quickly provide disaster information of spatial orientation after the Earthquake.
