【摘要】 地震灾区人口数据是破坏性地震发生时震害快速评估中一项重要的关键基础数据。本文利用GM(1,1)模型建立了甘肃省县一级人口数量的增长模型,实现了静态人口基础数据在地震发生时的动态计算,使其更接近于人口发展的实际情况,为震害评估提供更准确的人口基础数据。更多还原

【Abstract】 Population data in stricken-region is a fundamental and significant aspect in fast assessment of destructive earthquake.In this paper,a county level population growth model for Gansu province is set up by means of GM(1,1),and dynamic computing is operated based on static population data to better fit the actual situation,in order to provide more accurate population foundation data to fast earthquake disaster assessment.更多还原
