    摘要：以屋面生态节能板为研究对象，通过模拟试验，将播种密度和保水剂用量分别设计了3个处理组合，采用两因素交叉分组，加上对照组共10个处理组合，比较分析屋面生态节能板屋面内表面温度变化特征，研究了播种密度和保水剂用量对屋面生态节能板节能效应的影响。结果表明：屋面生态节能板温度效应的季节性差异明显，在夏季屋面生态节能板具有较好隔热效果，播种密度和保水剂用量对隔热效应有显著影响；在冬季屋面生态节能板体现出良好的保温作用，但播种密度和保水剂用量对保温效应影响不明显。

   Abstract：Based on the ecological energy saving board，the paper compared and analyzed the internal surface temperature variation characteristics of green roof. The seeding density and the amount of water-retaining agent were set 3 treatments respectively. There are 10 treatments including contrast by two factors cross grouping. It studied the effects of seeding density and water-retaining agent on the energy saving effect of roof ecological energy saving board. The results showed that seasonal differences have a significant effect on the temperature variation of roof ecological energy saving board. Roof ecological energy saving board has good heat insulation effect in summer and the seeding density and the amount of water-retaining agent have a significant effect on the insulation effect. Roof ecological energy saving board showed good insulation effect in winter but the seeding density and the amount of water-retaining agent had no significant effect on the insulation effect.
