Extracting indication information of floating population using SPOT5 and ground data: A case study of Xiamen, P. R. China

The floating population (FP) is a concept in the background of China´s particular household registration system. Most of the reported researches on FP were conducted with the census data and few of them concerned the potential value of remotely sensed (RS) data in the area. A methodology was described on how to extract indication information of the spatial distribution of FP using SPOT5 and ground data. The census data and the pollution source were obtained by field survey in Xiamen, P. R. China on the subdistrict scale in 2007. Meanwhile the land use and cover information was extracted from the fused SPOT5 image of the same temporality. According to the distribution of FP and pollution source point data, the built-up area was classified. The correlationships between FP and total population, type of built-up area, distribution of point source pollution respectively, were explored with SPSS (Statistic Package for Social Science).
