Abstract:: Facility agriculture become a high efficiency of agriculture planting industry due to the fast development in recent years.With the continuous development of urbanization，facility agriculture was the main agriculture production mode in Xiqing district.Based on the meteorological data of Xiqing meteorological observatory from 1971 to 2015，the characteristics of main facility agriculture meteorological disasters in Xiqing were analyzed by using linear climate tendency analysis methods.The results showed that low-temperature disasters in Xiqing was main mild low-temperature disasters，the frequency of low-temperature took on reducing tends in the recent 45 years.The trend of numbers of days of sparse sunlight was ascending significantly，the total number of severe few sunlight disasters was increased to 8 times.The major type of low-temperature and sparse sunlight was mild disaster，and the total number of occurrence was slowly rising.The occurrence of gale disasters was increased firstly and then decreased which also occurred more commonly light gale disasters，the total number of gale disasters was 82 times in recent 5 year.
