| 摘 要： | 根据每日天气预报资料,构建了日光温室外太阳辐射推算模型；根据日光温室透光率,构建了日光温室内太阳辐射推算模型.模型中考虑了天空云量对太阳辐射的遮挡,并利用吉林省吉林市永吉县双河镇日光温室对模型进行了验证.结果表明,模型能预测晴天和多云的日光温室外和室内到达土壤表面的太阳辐射的动态过程,模型推算值与实测值极显著相关,相对误差小于9.5％.

| Abstract: | According to the daily weather forecast information,the projection model of solar radiation outside greenhouse was constructed.According to light transmission rate of greenhouse,the projection model of solar radiation in greenhouse was constructed.The factor that solar radiation was covered by mounts of clouds was taken into account.Through the use of greenhouse in shuanghe town,Yongji county,Jilin province,the projection model had been verified.The results showed that the projection model could predict the dynamic process of solar radiation reaching the soil surface inside and outside greenhouse in sunny and cloudy days.The relevance between projected values from model and measured values was significant.The relative error was less than 9.5%. |
