摘要：
A geographic information system (GIS) and exploratory spatial data analysis were used to explore the complex spatial morphology of the urban benchmark land price digital elevation model (DEM) for residential use with Wuhan, China as a case study. The multi-dimensional spatial visualization gives a better understanding of the spatial characteristics of urban benchmark land prices with the results used to validate the urban spatial structure assumptions. The results indicate that the inverse distance weighted (IDW) method is more suitable for estimating the "terrace" spatial form of the benchmark land price. The "distance to the center", a classical space variable, is the best for depicting the urban spatial structure, each side view of the spatial form and its "price skyline", the land price distribution along the ring roads from inside to outside the city and the gradient of the price curves in all directions. All these reflect the "center to edge" distribution with all the prices gradually declining away from the center with significant spatial heterogeneity between city sectors. The slopes, aspect ratios and terrain curvatures further confirm the spatial features of "terrace" and "ring road radiation" of the urban benchmark land price DEM in Wuhan. © 2018, Tsinghua University Press.
