摘　　要：为了探索盘锦地区冬季日光温室光合有效辐射变化规律,更好地为本地区设施农业服务,利用2012年冬季日光温室内小气候和附近气象站观测资料,采用相关统计和逐步回归分析方法分析了冬季不同天气类型日光温室中光合有效辐射特征及光合有效辐射占太阳总辐射的比值,建立了冬季不同天气类型日光温室光合有效辐射的预报模型,并对其进行拟合检验。结果表明：（1）晴天和多云天日光温室内PAR具有明显的日变化。阴天时日光温室内接受到的PAR最大值一般在1~38W/m2。（2）冬季典型多云天ηPAR最高,阴天次之,晴天最低。（3）采用逐步回归分析方法分别建立日光温室内日最高光合有效辐射、日光合有效辐射总量、日最大总辐射、日总辐射总量与外界气象要素的相关模型均通过了0.01的显著性水平检验,并进行了拟合检验,晴天和多云天4个要素的拟合效果较好,阴天4个要素的拟合效果较差。In order to explore the law of photosynthetic and serve the region agricultural facilities better, microclimate and of the nearby weather station during active radxatlon m winter sunlight greenhouse ot ranjm based on the observed data of sunlight greenhouse winter in 2012, the methods of correlation analysis and stepwise regression analysis were adopted to study characteristics of photosynthetic active radiation in sunlight greenhouse and the ratio of photosynthetic active radiation to global radiation under different weather types during winter, and to set up forecast models of photosynthetic active radiation in sunlight greenhouse under different weather types during winter. The results showed that： （1） the daily variation of photosynthetic active radiation in sunlight greenhouse on sunny and cloudy days were both obvious, when it＇s cloudy photosynthetic active radiation in sunlight greenhouse was 1-38 W/m2; （2） ηpAR on typical cloudy day was the highest, on cloudy day was secondary and on sunny day was the minimum during winter; （3） the methods of stepwise regression analysis were respectively adopted to set up models of the highest daily maximum photosynthetic active radiation, the total daily photosynthetic active radiation, daily maximum global radiation, and the total daily global radiation in sunlight greenhouse associated with climate outside, the models passed the 0.01 level of significance, and fitting test had been carried out： 4 factors were fitted good on sunny and cloudy day, but poor on overcast day.
