城市居住人口空間分布的模擬研究——以廣州市天河區(qū)為例
[Abstract]:In order to solve the problem that the spatial representation of population data in administrative regions can not accurately reflect the actual distribution of population, this paper takes Tianhe District of Guangzhou as an example, uses high-resolution remote sensing image data, adopts object-oriented method to extract and classify buildings, and verifies and modifies the classification results in combination with the present land use map of Guangzhou. On this basis, the population density of residential buildings in each street of the study area is estimated by using the land use density method, and the spatial distribution model of urban population is further constructed by using grid method to simulate the spatial distribution of urban residential population. The results show that the population density of Tianhe District in Guangzhou is mainly concentrated in the banded area south of Guangyuan Expressway, and the population density in the central business district and industrial dense area is the highest, and the population density in the area near the main road is significantly higher than that in other areas, and the population density in Xintang, Phoenix, Changxing, Longdong streets far from the city center is low as a whole, and the simulation results are consistent with the actual situation in the study area. In this paper, the data are available, the operation method is simple, and the estimation accuracy is high. The research improves the efficiency of architectural interpretation and classification, and truly reflects the spatial distribution characteristics of urban population. The modeling method and research ideas have certain popularization significance.
