基于GIS的西安市人口空间分布变化研究
Study on spatial distribution of population in Xi'an city based on GIS
摘要
Abstract
Based on demographic data in Xi an city from 1985 to 2007, spatial distribution of population in Xi' an city was analyzed by GIS from spatial connection patterns, population density, gravity center of population, index of population concentration. Results showed that; (1) population distribution in Xi'an city significantly shows space assembling pattern on the whole, where in the part shows highly concentrated state in the city center, driving population growth in the peripheral urban? (2) the population increases continuously in Xi'an city, but growth speed is different among counties? The population in the center six areas increases quickly, while slowly in the near and far from the city? (3) population density is obviously distinct in spatial, which appears dense in the center and gradually sparse in the county around downtown area? (4) the gravity center of population changes with time, and change speed is different? The change direction can be divided into the northeast and northwest.关键词
