Urban planning, which has always been based on geographic space information for its design and management, and always been emphasized on basic accurate data, needs to based on more scientific information support. Geographic Information System (GIS), is playing a more and more important role in urban planning projects, with powerful functions in geographic information and space analysis. Its development promotes its applications in urban planning design, and vice versa.Taking the layout planning of primary schools and middle schools in Heping District, Shenyang City for an example, and through analysis in many factors associated with location planning of the primary schools and middle schools, including space distribution of the population, accessibility, and also the balance of school capacity and surrounding population, current situation of schools, and influence of purposes for land use, the paper makes comprehensive evaluation by space analysis and determines the optimized location zone as well as evaluation indexes.Finally the paper evaluates current situation of schools and original planning in two aspects, space distribution and school capacity, and came up with an improvement proposal of the primary schools planning. By comparison of current layout, original planning and improvement proposal, GIS's advantage in public facilities planning is certified. In addition, the conclusions of this paper have practical significance to optimization of planning proposal, site selection of new service facilities and etc., provide powerful support to primary and middle school layout planning and set up a reference platform for scientific decision-making.
