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, the urban population estimation method supported by the earth observation data is studied.Firstly, the residential area of the study area is divided into high density area, medium density area and low density area, and the IKONOS data is used to obtain various types of residential areas Then, through the linear correlation analysis, the relationship between residential area and resident population is studied and the correlation is established. Finally, the relationship between residential area and resident population is tested by using training data The results show that applying population - based observational data to urban population estimation is theoretically credible and methodologically feasible, which is a preferable method for population estimation in urban emergency situations.
