日光温室环境条件分析及其回归预测

本试验采用回归预测技术及相关关系分析，得出盖席后至揭席前这段时间内，室内气温与室外气温呈显著正相关，回归方程计算出，室外气温下降１℃，室内气温降低０．４℃；在有阳光条件下，室内气温主要与光照强度呈正相关，偏相关系数达到０．９１８５；室内地温与气温从下午３：００到第二天凌晨，呈显著或极显著正相关，上午至中午相关程度减弱甚至无关；湿度与气温间从早到晚表现为负相关→无关→显著正相关→无关→极显著正相关→负相关。掌握室内气温随外界条件变化的数字模型，对灾害性天气进行预测，主动地避免低温寡照的影响，使日光温室利用更趋合理。

Enviroment Condition Analysis and Regression Prediction in Sunlight Greenhouse

The utilization of sunlight greenhouse has been developed rapidly on north of China recently,but the researcg on relation between enviroment conditions in greenhouse and external meteiligecal factor was very few, By using regression prediction technoligy and correlation thet,the conclusion show that air temperature of inside and outside marked positive correlation from after cover met to before uncover regression quation indicate that temperature of outside dropes 1℃ the inside's fall 0.4℃;temperature is positive sorrelated to lightdensity in daytime. partial correlation coffcient is 0.9185,soil temperature is mared of most marked positive correlative to air's from 3:00 pm to early morning,but corrlation degree is weadend or uncorrelation from morn-ing to noon,Between humidity and temperature correlativity is negative correlation-uncorrelation- marked positive correlation-uncorrelation-most marked positive correlation-negative correlation. Regression equation is helpful to forecast disaster weather.
