Abstract:

The study of the frosty agricultural climate resources change, frosty agriculture climate resources change, frosty agriculture in Shenyang City, the smooth development, while avoiding disadvantages to provide a scientific based on Shenyang 1951-2010 meteorological data conventional mathematical statistical methods, analysis of the frosty light and heat water variation. The results showed that: the past 60 years due to climate warming in Shenyang City frosty period was shortened obviously, the meteorological elements at less stable. Compared with 1951-2010, nearly 30 years, frosty temperatures increased 0.9℃, high temperature increased by 5.7%; sunshing time was reduced to 66 h, the increase of 16.7%, increased in precipitation 8.3 mm, much rain and snow, an increase of 5%; cloudy days increased 6 days, the probability increased by 8.3%; windy days in reducing, big blizzard number of changes smoothly. Continuous cloudy scant sunlight, temperatures rose to changes in unstable was climatic characteristics of the winter of Shenyang City, a greater impact on the winter agricultural development, only to improve the facilities for modernization of agricultural equipment, intelligent features, in order to play a better thermal efficiency of resources.
