Based on literature review method,Kriging interpolation,GWR model and analysis on spatial variation characteristics of 2004-2011 residential land price in Wuhan city,this paper screens factors of residential land price and builds GWR model(geographically weighted regression) to explore the regional differences of residential land price influenced by each factor which will provide advice to urban planning and real estate development from the micro perspectives.The result shows that,first,the space of residential land price in Wuhan demonstrates single-centered structure on the whole,and shows a diminishing circle style with the increasing distance from the city center; second,the main road,metro and planning control (floor area ratio) have the big influence on residential land price; thirdly,planning control,main roads,supermarkets and educational resources have obvious spatial differentiation characteristics to residential land price.All the above factors on residential land price have great influence in different micro-locations and the obvious difference is statistically significant.
