Abstract:

There are some problems in making thematic maps, such as cumbersome model calculation process, large amount of data processing and heavy mapping tasks. To improve the production efficiency and timeliness of maps, Python language, ArcGIS and database are used to develop data processing and thematic map making software, and an automatic mapping system for regional crop productivity is built in this study. The system collects meteorological data in real time, runs productivity model, and designs thematic map of regional crop productivity. Based on the case analysis of crop productivity mapping in Anhui Province, the simulation results are similar to the actual situation. After adjusting the geographical base map and meteorological stations, the simulation results can be directly applied to the crop producing areas in the central and east of China, providing information technology support for the stable yield of regional food crops.
