摘　　要：研究朝阳市设施农业生产期气候资源。结果表明,在设施农业生产期朝阳地区太阳总辐射和日照时数都存在减少趋势,太阳总辐射量趋势减少12.56～28.05kJ/cm2,气候跃变前、后太阳总辐射平均减少7.12～11.72kJ/cm2;日照时数趋势减少104～233h,气候跃变之前、后,平均减少58～104h。热量资源趋势增加,平均气温升高2.6～2.9℃,气候跃变前、后气温平均升高1.3～1.5℃。阴天日数和冻土深度趋势减少和变浅,这对发展设施农业十分有利。The climate resource of facility agriculture in production period in Chaoyang City was studied.The results showed that：in the facility agriculture production period,global solar radiation and sunshine duration were present downward trend,the trend in global solar radiation reduced 12.56-28.05 kJ/cm2,climate jump before and after the global solar radiation reduced by 7.12-11.72 kJ/cm2;sunshine trend decreased 104-233 h,before and after climate jump,the average reduction of 58-104 h.Increase the heat resource trends,the average temperatures 2.6-2.9 ℃,climate jump before and after the temperature increased an average of 1.3-1.5 ℃.Cloudy days and the trend to reduce and shallow depth of frozen soil,which is very beneficial to the development of facilities for agriculture
