服务于地震应急的人口格网精细化研究——以合肥市为例

Earthquake Emergency Servicel:Taking Hefei City as an Example

运用遥感、GIS技术和数学建模理论,结合DMSP/OLS夜间灯光数据、人口统计数据、建筑数据对人口格网数据进行精细化、实时化研究,模拟合肥市500m×500m的格网人口分布数据,并进行精度验证。研究结果表明,网格精细化的人口数据能够客观的反映研究区的人口密度分布情况,为地震灾害损失快速评估提供数据支持。

Using remote sensing,GIS technology,and mathematical modeling theory,combined with DMSP/OLS nocturnal light data,demographic data and building data,we carried out a refined and real-time research on population grid data to simulate the distribution data of population density for the grid of 500 m × 500 m in Hefei city and verified its accuracy. The results show that the population distribution data in refined grid can objectively reflect the distribution of population density in the study area,which could provide effective data support for the rapid assessment of earthquake disaster losses.
