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。
In recent years, rapid development of facility agriculture has become a highly profitable industry in agricultural planting. With the continuous development of urbanization, agricultural production in Xiqing District is dominated by facility agriculture. Based on the daily meteorological data of Xiqing meteorological observatory during the period from 1971 to 2015 (from December to February of the following year), the linear trend was used to calculate the change trend of the feature quantity. The characteristics of agricultural meteorological disasters in the greenhouse were studied analysis. The results show that the low-temperature disasters in Xiqing are mainly mild low-temperature disasters, and the number of low-temperature disasters occurring in the past 45 years tends to decrease as a whole. The number of days with undeclared and the total number of cloudy days shows a significant upward trend. From 2001 to 2010 The number of severe and cloudy incidents increased to 8 times. The low and low-temperature disaster was mainly mild, and the total number of disasters tended to increase slowly. The main wind disaster was mild disasters, with the total number of occurrences decreasing first and then increasing Trend, the total number of wind strikes in the past 5 years was 82 times.
