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。
Research on Chaoyang City facilities agricultural production climate resources. The results showed that the total solar radiation and sunshine hours in Chaoyang area during the period of agricultural production were decreasing, the trend of total solar radiation decreased 12.56 ~ 28.05kJ / cm2, and the average solar radiation before and after climate change decreased by 7.12 ~ 11.72kJ / cm2; sunshine duration decreased 104 ~ 233h, before and after the climate change, an average reduction of 58 ~ 104h. The trend of heat resources increased with the average temperature rising 2.6 ~ 2.9 ℃. Before and after the climate change, the average temperature increased by 1.3 ~ 1.5 ℃. The trend of cloudy days and permafrost has been declining and shallowing, which is very beneficial for the development of facility agriculture.
