根据2006-2007年、2008-2009年冬季日光温室内小气候和附近气象站观测资料,利用相关和逐步回归分析,对不同天气状况下石家庄地区日光温室冬季小气候特征及其与外界的关系进行了研究.结果表明,晴天和少云-多云天气下日光温室内的气温、空气相对湿度、接受到的最大太阳辐射有明显的日变化;连续寡照时,室内全天气温低,空气湿度大,不利于蔬菜正常牛长发育.影响日光温室内小气候的主要因子有外界的日照时数、平均气温、最低气温、最高气温、空气湿度、云量以及温室内前一天的最高气温等.建立了日光温室内外气象要素的相关模型,经拟合检验和应用检验,不同天气状况下日光温室内日最低气温、最高气温、空气最小相对湿度、接受到的最大太阳辐射的平均绝对误差分别在1.1℃、2.5℃、5.8%、58.3W·m~(-2)以内,平均相对误差大部分在10%以内,具有较高的精度.
根據2006-2007年、2008-2009年鼕季日光溫室內小氣候和附近氣象站觀測資料,利用相關和逐步迴歸分析,對不同天氣狀況下石傢莊地區日光溫室鼕季小氣候特徵及其與外界的關繫進行瞭研究.結果錶明,晴天和少雲-多雲天氣下日光溫室內的氣溫、空氣相對濕度、接受到的最大太暘輻射有明顯的日變化;連續寡照時,室內全天氣溫低,空氣濕度大,不利于蔬菜正常牛長髮育.影響日光溫室內小氣候的主要因子有外界的日照時數、平均氣溫、最低氣溫、最高氣溫、空氣濕度、雲量以及溫室內前一天的最高氣溫等.建立瞭日光溫室內外氣象要素的相關模型,經擬閤檢驗和應用檢驗,不同天氣狀況下日光溫室內日最低氣溫、最高氣溫、空氣最小相對濕度、接受到的最大太暘輻射的平均絕對誤差分彆在1.1℃、2.5℃、5.8%、58.3W·m~(-2)以內,平均相對誤差大部分在10%以內,具有較高的精度.

Based on the observed data of plastic sunlight greenhouse microclimate and neighbouring weather stations during the two winter periods following as 2006-2007 and 2008-2009, using the method of related statistical analysis, the characters of plastic sunlight greenhouse microelimate and the relationship between the microclimate and outside weather conditions in Shijiazhuang area during the winter are studied. The result indicated that the microclimatic factors have obvious diurnal variations under these weather condions such as sunny day, slight cloud-cloudy day. Persistent sunless days can result in lower temperature and higher air humidity inside greenhouse, which could be harmful to the normal growth of cucumber. The main factors affecting the microclimate were as follows, sunshine hours, average temperature, lowest temperature, highest temperature, air humidity, cloudage outside and the yesterday's highest temperature in-side. The correlation model of weather factors inside and outside the plastic sunlight greenhouse has been set up, which has high accuracy verified by historical data and application. The model's accuracies of low-est temperature, highest temperature, air relative humidity, and largest solar radiation under different weather conditions are within 1.1 ℃, 2.5 ℃, 6% and 58.3 W·m~(-2). Most of the average relative errors are below 10 percent.
