Analysis of the Characteristics of the Frosty Agro-climatic Resources of Shenyang City
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 to 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 to 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.
