摘　　要：分别对砖墙、加气混凝土墙、砖墙与珍珠岩复合墙以及砖墙与苯板复合墙这4种墙体的热阻、热惰性指标和热流密度进行计算,通过分析比较,得出砖苯复合墙体保温性最好,加气混凝土墙体热稳定性最好。综合保温和热稳定性以及保护耕地节约能源考虑,加气混凝土墙体是温室北墙的最好材料。Through computing the thermal resistance, thermal inertia index and heat flux, four types wall including brick, aerocrete, brick-perlite and brick-polystyrene foam walls were compared. Results showed that brick-polystyrene foam wall was the best one according to the heat preservation and the aerocrete was best according to the heat stability. Combining these two and cultivation soil protection and energy saving, aerocrete was the best one for greenhouse north wall.
