Abstract: As the main text materials arising from the service that meteorology performs for agriculture, ten day, monthly agro meteorology report, or disaster report demands both high reliability and strict time effectiveness.Nevertheless, compiling reports, a task which entails considerable manpower and time, has high demand on compilers professional knowledge and writing ability.To tackle the above issues, a construction method of agro meteorological parlance dismantling and topological lexicon based on topological theory was advanced under the support of MeteoGIS platform and the reference of agro meteorological expert system.Thus, a knowledge base of classified parlance, which specializes in agro meteorological key feature temporal and spatial expressions, was built.Based on the preliminary research results of parlance reorganization model, summary statistics from the agro meteorological observation data, quantitative analysis, chart generation, language editing are realized automatically in the whole process, and automated generation of agro meteorological information documents was basically realized by taking advantage of the topological theory of the classified parlance knowledge base and model base of temporal and spatial expressions of agro meteorological key feature.The research results showed that automatically generated documents, which could be issued with little artificial polishing,enjoyed more objectiveness,comprehension, specification and accuracy than artificial writing.Time to compile documents was greatly shortened, and subjective deviation was weakened.This technique will contribute to the advent of a new stage where supportive technology served by scientific data shifts from data entry paperless, electronic management, statistical tabular, graphical analysis and visualization to documentation service.
