天津近郊设施农业气候资源与气象灾害变化特征

Variation Characteristics of Facility Agro-climatic Resources and Meteorological Disaster in Tianjin Suburb Area

城市近郊是设施农业生产的重要区域,对近郊气候资源和气象灾害变化的研究有利于提高设施农业生产的防灾减灾能力。现对1971—2010年天津4个郊区在设施农业生产季的气候资源和气象灾害进行了分析,探讨在气候变化背景下设施农业气象灾害的变化规律。结果表明:在近40年中,该区域气温条件的变化利于设施农业生产,而光照资源则显著下降,低温、大风和降雪等灾害总体减少,寡照成为影响设施农业生产的首要气象灾害,尤为应引起注意的是极端气象灾害事件仍不时发生。

It has been known that suburban area is an important region for facility agriculture production.And do some research work on studying variation characteristics of facility agro-climatic resources and meteorological disaster would be beneficial to improving the ability of prevention and mitigation disasters.There were 40 years meteorological element and facility agro-meteorological hazard records of four suburbs around Tianjin from 1971 to 2010had been analyzed in this paper,to discuss change rule of facility agro-dimatic resources under background of climatic variation.The results showed that climate change has been becoming more and more favorable for facility agricultural production in the past 40 years.But less sunlight became the major disaster of facility agricultural production,and chilling weather,gale and blizzard became less and less.However,extreme weather events would happen from time to time.
