北京地区日光温室室内外环境要素特征分析

Feature Analysis of Indoor and Outdoor Environmental Factors of Solar Greenhouse in Beijing

通过自动环境气象站连续观测了北京顺义地区2017年8月-2018年8月的日光温室室内外温湿度、太阳辐射和光合有效辐射4种环境要素,探究不同环境要素在室内外和季节之间的变化规律。试验结果表明,室内外温度具有极显著的相关性,室内温度始终高于室外,并随着春季到冬季季节的交替,室内外的温差逐渐增大。室外湿度受降水影响较大,因而夏秋季节室外湿度高于室内,而冬春季节则相反。一年中室外太阳辐射和光合有效辐射均高于室内,而季节间的辐射值受天气状况影响较大,各季节的辐射值以春季最大。

Four environmental factors,including indoor and outdoor temperature and humidity,solar radiation and photosynthetic effective radiation were continuously observed from August 2017 to August 2018 in Shunyi district,Beijing through automatic environmental meteorological station,to explore change rule of different environmental factors between indoor and outdoor and season. Results showed that indoor and outdoor temperatures had a very significant correlation,with indoor temperature always higher than outdoor,and the temperature difference between indoor and outdoor gradually increased with the spring to winter seasons. The outdoor humidity was greatly affected by precipitation,so the outdoor humidity was higher in summer and autumn than indoors,while the winter and spring were opposite. The annual solar radiation and photosynthetic effective radiation were higher in the outdoor area,and the seasonal radiation was greatly affected by weather conditions. Outdoor solar radiation and photosynthetic effective radiation were both higher than indoor radiation,and inter-season radiation was greatly affected by weather conditions,and the maximum value of radiation was in spring.
