- 摘要:
- 近年来设施农业发展迅速，成为农业种植业中效益较高的产业，随着城镇化的不断发展，西青区农业生产主要以设施农业为主。该研究利用1971—2015年西青区气象观测站冬季（12月至翌年2月）的逐日气象资料，以线性倾向估计计算特征量变化趋势的方法，对该区日光温室农业气象灾害特征进行了分析。结果表明：西青区发生低温灾害以轻度低温灾害为主，近45年间发生低温灾害的次数整体呈减小的趋势；寡照日数和总连阴天次数呈显著上升的趋势，2001—2010年重度连阴天灾害发生次数增长至8次；低温寡照灾害以轻度为主，灾害发生次数总数呈缓慢上升的趋势；大风灾害以轻度灾害为主，且总发生次数呈先减后增的趋势，近5年内发生总的大风灾害次数为82次。
- 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.
