Abstract: Based on the 3S techniques, automation meteorological station, radar, satellite, mathematical forecast and SMS technique, the monitoring and early warning system for agro-ecological and agricultural meteorological disaster was built in Shaoxing city. Through this system, the areas of invaded and occupied cultivated land were monitored, distribution characteristics of agricultural natural resources such as water resource, land utilization coverage were analyzed, and the agricultural meteorological disaster was monitored and early warned. The system provides a technological support for using local natural resources advantage to lighten meteorological disaster loss effectively, and to promote sustainable development of agriculture.
