摘要
介绍了人口、房屋数据空间化的方法,以伊犁地区为例建立了一个符合非均匀密度分布的公里格网人口和房屋数据模型,并将其进行空间化,最后利用实地调查数据对结果进行了验证。通过数据检验,公里格网的人口密度数据、房屋密度数据客观地反映了伊犁地区统计单元内承灾体的空间分布,具有较高的精度,为地震应急救援和决策提供可靠的依据。
This paper introduces the data space method of population and the housing,taking Yili area as an example to establish a consistent with km grid population and housing data model of non-uniform density distribution,and its space,finally the result was verified by the field survey data.Through data inspection,population density data,1km grid housing density data reasonably reflect the demographic unit and the actual housing distribution,has higher precision,and provide reliable basis for earthquake emergency rescue and decision.
