摘要
专题图制作存在模型计算过程繁琐、数据处理量大、制图任务重等问题,为了提高制作效率和出图时效性,利用Python语言,结合ArcGIS、数据库,开发数据处理、专题图制作软件,搭建区域作物生产力自动化制图系统。系统通过实时采集气象数据,运行生产力模型,制成区域作物生产力专题图。对安徽省作物生产力制图的实例进行分析,系统模拟结果与实际情况相近,在调整地理底图和气象站点后,可直接应用于中国中东部作物产区,为区域粮食作物稳产提供信息技术支撑。
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.
