【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]:In recent years, facility agriculture has developed rapidly, and has become a more efficient industry in agricultural planting. With the development of urbanization, the main agricultural production in Xiqing area is facility agriculture.Based on the daily meteorological data in winter (December to February of the following year) of Xiqing District Meteorological Observatory from 1971 to 2015, the characteristics of agrometeorological disasters in solar greenhouse in this area were analyzed by using the method of linear tendency estimation to calculate the variation trend of characteristic quantity.The results showed that the low temperature disaster occurred mainly in Xiqing area, and the frequency of low temperature disaster decreased in recent 45 years.The number of days and the total number of continuous overcast days increased significantly, and the frequency of severe continuous overcast disasters increased to 8 from 2001 to 2010, while the low temperature disasters mainly occurred slightly, and the total number of disasters increased slowly.The main gale disasters are mild disasters, and the total occurrence times show the trend of first decreasing and then increasing. In the last 5 years, the total number of windy disasters is 82 times.
