| 摘 要： | 社会经济数据是研究城市发展的重要因子,而传统的社会经济数据由于与空间坐标不统一,对城市发展的空间变化难以提供有力的支持。本文利用DMSP/OLS灯光数据,基于生态控制线,通过回归运算制定深圳市2010年人口指数模型,得到深圳市2010年1 km~2人口空间化图,有利于对深圳市人口的空间分布特征进行分析,为城市的绿色发展提供依据。

| Abstract: | Socioeconomic Data is an important factor in Urban development research,but traditional socioeconomic data does not has spatial coordinates;it is difficult to provide strong support for the research of spatial change in urban development.This paper used DMSP/OLS data and Land-Use Change Investigation Data to constitute Shenzhen 2010 population index model which is based on ecological control line and regression operation,and then there was a spatial population map which accuracy is one kilometer.This paper is helpful to analyze the spatial distribution of the population in Shenzhen,and to provide the basis for the further development of the city. |
