Abstract:

To fully utilize of climate resources to adapt to climate change and avoid the risk of meteorological disasters of the facility agriculture in frost period, the meteorological data of northwest of Liaoning was used to analyze the climate resources change in frost period, and the countermeasures of meteorological service for frost period agriculture facility were discussed. The results showed that the temperature in frost period increased and was unstable in northwest of Liaoning Province, the extreme minimum temperature was more prominent, the snow in frost period increased, the number of cloudy days increased, the sunshine time decreased, the total solar radiation weakened, the wind intensity increased, and the extreme weather phenomenon in frost period had a significant impact on the facility agriculture in frost period. To promote the development of facility agriculture in frost period, it was necessary to establish an integrated service system of evaluation, monitoring and early warning meteorological services from the aspects of facility agriculture engineering, environmental control, energy saving by using climate resources and adaptation to climate change. A professional, dynamic, diversified and refined facility agricultural meteorological service warning platform should be built to improve the ability of disaster prevention and reduction and ensure the sustainable development of facility agriculture in frost period.

Key words: facility agriculture in frost period, climate change, agrometeorological services, countermeasure
