Abstract: Meteorological disasters are one of main reasons affecting modern agricultural production．Strengthening meteorological monitoring, forecasting, and early warning work, and providing timely meteorological information, can effectively reduce agricultural production losses．An agricultural meteorological system was developed based on LBS, location-based agricultural activity reminders and agricultural meteorological disaster prediction warnings were released to users, achieving refined meteorological services for agricultural conditions．The system relied on Zhejiang intelligent grid meteorological data and agricultural meteorological service indicators to release LBS based agricultural suitability and meteorological disaster risk reminders for different crops at different times; by matching the user's farm location and associated crop types, agricultural suitability and meteorological disaster level of each crop owned by the user at different times were obtained, and agricultural meteorological impact situation in the next 6 days was dynamically displayed to the user．Since its launch in 2018, the system has achieved good application results in helping farmers cope with meteorological disasters．
