The basic green infrastructure in urban areas, urban green space typically performs important ecological and socio\|economic functions. It is the most important spatial type in the urban planning construction. As the spatial base of the harmony between human and nature in urban area, urban green space is a spatial adjuster that improves the structure and function of urban system and is viewed as an important spatial carrier to guarantee the sustainability of urban development. In this study, Shanghai city was chosen as a case. Based on 689 resident samples, by the support of spatial analysis function of GIS, the amenity value of urban green space was estimated through twenty three variables out of four types of factors (house structure, accessibility, area, landscape metrics) using Hedonic Price Model (HPM). The results showed that: (1) urban green space had amenity value, and the spatial distribution, size and types had significant influence on the price of house, but the influence was different; (2) the residents had the trend to live close to green space, and then there was a ring social pattern around the large green space; (3) the influence of landscape metrics on house price indicated that the pattern of green space was also an important factor; (4）the characters of house structure such as size, age are the basically internal factors, while the extrinsic factors comprise the time to urban center, to the nearest hospital, college, Metro station, in addition to urban green spaces. The amenity value analysis on green space can put forward useful information and reference which can be used for the urban green space plan and urban development strategy plan by urban planners and policy\|makers.
