Research of Digital Planning and Simulation Scheme of Reconstruction of Changchun Typical "Koa Architecture"——Take the Pseudo Manchuria State Council Site as an Example

After the massive investigation in Changchun "Koa Architecture" and by using the survey data collation and analysis,the article puts forward the report of digital planning and simulation research on the reconstruction plan.With the result,city planners could compare and balance the protection of historical buildings and rationality and economy of reuse technology in a new platform.Using 3D digital software in Changchun typical "Koa Architecture" —the Pseudo Manchuria State Council,the article makes an analysis of digital restoration and planning for the future simulation research,which would not only play a positive role in deep study of the style of architecture,but also promote the process of digital city.
