摘要：

为了提高设施农业气象服务水平，减轻气象灾害对日光温室蔬菜生产的影响，利用2008—2011年冬季日光温室内外气象观测资料，采用相关及逐步回归分析方法，对冬季日光温室内温度变化特征及最低气温预报模型进行分析研究。结果表明，晴天和多云天气下日光温室内的气温有明显的日变化，且晴天状况下温度变化幅度要大于多云天气；连阴天时日光温室内气温较低，严重影响植物正常生长发育。日光温室内最低气温与室外气温及室内湿度、气温、地温相关性较好。试验建立了日光温室内最低气温预报模型，利用最新资料对模型进行预报检验，不同天气状况下日光温室内最低气温预报值平均绝对误差小于1℃，平均相对误差低于10%。

Abstract:

In order to improve facility agro-meteorological services, and mitigate the impact of meteorological disasters on greenhouse vegetable production，based on the meteorological observation data inside and outside the solar greenhouse in winter during 2008-2011, the temperature characteristic and the minimum temperature forecast model inside the solar greenhouse in winter were studied by using correlation and stepwise regression analysis method. The results showed that the temperature inside the solar greenhouse had an obvious diurnal variation in sunny and cloudy days, and the range of temperature change was greater in sunny days than in cloudy days. The temperature inside the solar greenhouse was lower in continuous overcast days, and it seriously affected the normal growth and development of plants. The minimum temperature inside the solar greenhouse was preferably related to the temperature outside the solar greenhouse and the humidity, temperature and soil temperature inside the solar greenhouse. The minimum temperature forecast model inside the solar greenhouse in winter has been set up. The forecast model has been verified by recently data. The average absolute errors of the forecast minimum temperature inside the solar greenhouse in different weather conditions was less than 1℃, and the average relative errors were below 10%.
