摘　　要：为提高人口、房屋数据空间化精度,在甘肃省内随机抽取311个网格单元(1km×1km)的人口、房屋数据为样本,建立基于抽样数据的人口、房屋分布模型。将其应用到2013年岷县漳县Ms 6.6级地震灾害快速评估中,结果显示,用人口、房屋空间数据得到的快速评估结果具有较高的精度和可信度。基于抽样的人口、房屋数据空间化方法可以较好地反映甘肃省实际人口、房屋分布情况。In order to improve the accuracy of population and housing grid spatialization,this paper introduced a population and housing gird spatialization module based on 311 random grid＇s samples（1 km ×1 km）from Gangsu Province.The module was then tested in the rapid earthquake loss assessment of the Ms6.6 earthquake in Min County and Zhang County in 2013.The results showed that the module had high accuracy and reliability of population and housing grid spatialization.

关 键 词：人口数据空间化 房屋数据空间化 地震快速评估
