成都市商品住宅价格空间分异特征与规律

The Characteristics and Laws of Spatial Differentiation of Housing Prices in Chengdu

以成都市商品住宅为研究对象,通过ArcGIS等方法,研究成都市商品住宅价格空间分异特征和规律。结果表明:成都市商品住宅价格总体上呈现出由中心向外围降低的趋势,中心城区主要呈团块状分布,近郊区主要呈放射状分布,远郊区主要呈星岛状分布;低房价区段在西部—北部—东部地区呈现2条“半环状”分布;中低房价区段呈“环状+放射状”分布。在中心城区形成了环状分布,在近郊区及远郊区形成了自中心城区向外延伸的放射状分布特征;中房价区段在中心城区分布相对集中并呈团块状分布,在近郊区呈放射状分布,远郊区呈零星分布特征;中高房价区段在中心城区、高新区、天府新区呈组团状分布,在近郊区呈放射状分布,远郊区呈零星分布的特征;高房价区段自中心城区沿天府大道向南延伸至天府新区,形成了南—北走向的峰值带。

This paper studies the differentiated spatial characteristics and laws of housing prices in Chengdu with ArcGIS.The research shows that the housing prices drop from downtown areas to suburbs.In central areas, housing prices surge in certain residential clusters;in suburban areas, prices decline from near suburbs to remote suburbs.But in outer suburban areas, the prices show a dispersive layout.The low housing price zones are identified as two “semi-loops” lying at the west-north-east part of the city.The medium-to-low price zones are identified as laying out in the “circular and radial” shape, with loops in the central areas radiating from the center to the outer areas.The medium price zones are identified as clusters in the downtown areas, radials in the near suburban areas, and sprinkles in outer suburban areas.The high price zones concentrate in the central districts of Gaoxin District and Tianfu District as clusters, locate in the near suburban areas in ray-shape, and sprinkle in outer suburban areas.The high price zones extend south from the central areas to Tianfu Zone as a peak housing price belt.
