克拉玛依冬季气候变化特征及其对设施农业的影响

Climatic Change Characteristics of Karamay in Winter and Its Influence on Facility Agriculture

利用1961—2009年克拉玛依气象站气候资料,对冬季设施农业的主要生产阶段(12月—次年2月)的热量条件和光照条件进行分析。结果表明:克拉玛依冬季呈增暖趋势,平均最低气温增暖尤其显著,热量条件变化有利于设施农业;但日照时数显著减少,降雪日数、雾日数不显著增多,对设施农业生产有不利影响;同时,灾害性天气及极端气候事件的影响不可忽视。针对克拉玛依冬季气候变化特征,在发展设施农业的同时,需要加强气象灾害防御措施。

Using the climatic data during 1961-2009 from Kalamayi weather station,we analyzed the thermal condition and light condition during the main production stage of facility agriculture in winter（from December to the the next February）.The results indicated that the winter temperature assumes warming tendency,and mean minimum temperature increases remarkably.The thermal condition change was advantageous to the facility agriculture.But the sunshine hours reduced obviously,the snow days and foggy days increased,which affected adversely the facility agriculture production.At the same time,the disaster weather and extreme climate events could not be ignored.In view of the winter climatic change characteristic in Kalamayi,when developing facility agriculture,we should strengthen the meteorological disaster defensive measures.
