| Abstract: | In the new era, research about spatial expansion of urban residential land needs more accurate data to support. In this article, we take urban area of Chongqing as study area. Based on the multi origins of big data about urban residential quarter, this research aimed to investigate spatial characteristics and driving factors of expansion of residential land use in the past 20 years by borrowing a variety of models such as standard deviation ellipse, buffering analysis, extended intensity index, landscape pattern analysis and geographic weighted regression, etc. The research reveals: 1) The layout of residential quarters in urban area of Chongqing shows core-peripheral structure. The average area of residential quarter gradually increases from core to peripheral area. 2) The expanding process of residential land in urban area of Chongqing went through growing transition of from rapid growth phase to growth declining phase. Area of residential land expanded rapidly between 1999 and 2003. The expanding direction of residential land in urban area of Chongqing is mainly north-south direction in the former decade, and the east-west trend becomes increasingly significant in recent years. 3) The driving factors of expansion of residential quarters in urban area of Chongqing include the distance from Sub-urban center, road network, metro stations, density of hospital and slope. 4) The influence of the same driving factor on the expansion of residential quarters in different locations has obvious spatial heterogeneity. |
