基于对地观测数据的城镇人口估算方法研究(英文)

Research on the Method of Population Estimation in Urban District Based on EO Data

本文对对地观测数据支持下的城镇人口估算方法进行了研究.首先,将研究区的居民地划分为高密度区、中密度区和低密度区,并且通过解译IKONOS数据获取各类型居民地的面积;然后,通过线性相关分析,研究居民地面积与居民人口之间的相关关系,并建立了相关关系式;最后,应用训练数据对居民地面积与居民人口之间的关系式进行了检验.结果显示:应用对地观测数据进行城镇人口估算,在理论上可信、方法上可行,是城镇应急状态下进行人口估算的可取方法.

In this paper, a method to estimate the population in urban districts by using EO （Earth Observation） data has been studied and discussed. Firstly, in this investigation residential districts have been classified into three kinds, which are high-dense, middle-dense and low-dense, and the area of each kind has been calculated by interpreting IKONOS. Then, the correlation between the population and the residential area has been studied by using the linear analysis, and an equation showing the correlation between the population and the residential area has been determined. Finally, the equation between the population and the residential area has been tested. Results show that it is a reasonable and adoptable way to estimate the population by using EO data in some urgent situations in urban districts.
