Abstract: Territorial spatial planning is a scientific guide to guide the national space development, coordinating all kinds of spatial planning. In the process of design and implementation of territorial spatial planning, it is necessary to use a large number of collected multi-source heterogeneous data after processing. This study aims at the differences of spatial planning data from different sources in format, coordinate reference, attribute structure and so on. Based on the technology of big data, GIS, artificial intelligence and various self-research algorithms, a method of spatial planning data fusion is proposed in this study, which consists of four steps: data cleaning, data conversion, place name and address matching connection and batch processing. The techniques and methods used are integrated into a“One-click” tool to realize batch fusion of multi-source heterogeneous spatial planning data. The fusion method of multi-source and heterogeneous spatial planning data designed in this study can share the data of different data sources, different storage formats, different space-time, different scales and different coordinate systems without loss, and process the data in batch and automatically, so as to improve the utilization efficiency and management level of territorial spatial planning data.

Key words: territorial spatial planning, multi-source data fusion, address matching
