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.
