Abstract: The occurrence and development of architectural heterogeneous factors transplantation in Beijing were studied for the purpose of reducing the impacts on the regional traits development,caused by the three typical heterogeneous factors,heterogeneous urban morphology,heterogeneous architectural type,and heterogeneous architectural style.By using the methods of inductive argument and case analysis,the two main courses of the heterogeneous factors transplantation was analyzed since China's reform and opening up,and the deep motivations behind the phenomenon,which were strong economic driving forces,rapid development of transport,and cultural diffusion in rapid rate were studied.Based on the global city positioning of Beijing,the development significance of the heterogeneous factors transplantation was discussed,and two principles,including the principle of reducing the destruction to the old city and the principle of making the meaning association between the new and the old city were put forward to guide and prescribe the development of heterogeneous factors transplantation.
