Abstract: Land suitability analysis is the necessary premise for spatial distribution planning of urban green space. Based on the status investigation and statistical data, and by using multi-factors evaluation method, this paper evaluated the land suitability of green space in Shenyang City. The weights of affecting factors were decided by analytic hierarchy process (AHP) and pair-wise comparison, the suitable area for green space construction was analyzed based on the spatial analysis module in ArcGIS, and the identified land resource for green space construction was determined for the green space system planning and development direction in Shenyang in the future. In the City, the most suitable area for urban green space construction took 11.1%, suitable area took 19.2%, basically suitable area took 23.3%, unsuitable area took 29.5%, and unavailable area took 16.5%. According to the results, suggestions were provided on the spatial distribution of the construction of urban ventilation, urban group green space, and urban green space ecological network to highlight the urban green space system planning of Shenyang.
