[Objective] To simplify the production of agricultural drought monitoring, evaluate the operational procedures of products and improve the refinement of monitoring and evaluation maps. [Method] With GIS and mathematics, meteorology, management science, computer science and other technical means and subject knowledge as the core, a drought monitoring and assessment system based on GIS technology was developed. [Result] The system was used to monitor the drought in Guangxi on November 4, 2006 and tested with the actual situation, which proved that good monitoring results were obtained. [Conclusion] GIS-based agricultural drought monitoring and evaluation system realized the organic combination of GIS and professional monitoring and evaluation models, provided flexible human-computer interaction interface and visual expression, realized the monitoring and evaluation function of agricultural drought and had better performance Practicality and advanced.
