Multi-source information fusion realizes the complementary integration and comprehensive utilization of multi-source informa-tion by integrating,processing and correlation analysis of multi-source heterogeneous data.GIS can achieve the integration and fusion of multi-source heterogeneous information services such as vectors,grids,3D models,and real-time sensor data.As for urban planning,decision-making level information fusion is available by targeted functional development based on data fusion.Combined with the specific practice of multi-planning integration and 3D digital urban decision-making system construction in Zhangqiu District,this paper expounds the implemen-tation process in detail for multi-source data acquisition,processing,integration,association fusion and system customization development.Facts have proved that multi-source information fusion is of great benefit to the upgrading of planning methods and the improvement of deci-sion-making level in Zhangqiu District.
