Abstract:

With well distributed weight linearity running mean processing method, Analysis all previous years grain yield, Will reduce production the scope ≥5% years to decide as the model underproduction year, Analyzes through the meteorological disaster, Discovers creates the grain underproduction the main meteorological disaster. The result indicated: The drought and the waterlogging caused by excessive rain disaster are create the local grain underproduction the main meteorological disaster. Along with grain yield level promotion, The meteorological disaster creates the economic loss assumes enlarges the tendency. While strengthens drought resisting, protection against waterlogging engineering construction's, Should strengthen to the airborne water resources development use, Simultaneously must promote the saving water irrigation technology vigorously, The full display limited water resources's maximum economic efficiency, is the agricultural sustainable development safeguard.
