| 摘 要： | 根据朝阳县霜期设施农业的特点，结合地方气候条件，分析霜期农业气候资源变化趋势，为霜期农业顺利发展提供气象技术。结果表明．霜期总辐射平均为54．56KJ／m^2，气候倾向率为-0．835KJ／（m^2·10a），历年霜期总辐射趋势减少4．68KJ／m^2；霜期日照时数平均为1528h，气候倾向率为-41．021h／10a，趋势减少230h；霜期平均气温为0．1℃，气候倾向率为0．527℃／10a，趋势升高2．9℃。霜期阴天日数趋势减少2．9d，冻土深度趋势变浅27cm。气温升高热量资源增加，阴天日数和冻土深度趋势减少和变浅，可节省设施农业能源消耗。光能资源趋势下降警示人们要注意光资源的变化。低温、积雪和大风灾害天气是霜期设施农业的防御重点。 |
