暖棚夜宿+干草补饲组合是我国高寒草原冷季养殖牦牛的重要方式。然而，过于薄弱的围护结构导致暖棚夜间的增温效果仅为6.28℃，而干草作为一种价廉易得的高效保温材料，却需另建囤积空间，故应考虑如何利用干草加强暖棚围护结构的热工性能。基于EnergyPlus的模拟计算结果，分析各种干草保温措施对暖棚内热环境及增温效果的影响，确定合适的干草保温方案，暖棚夜间的增温效果提高到9.47℃。干草保温既提高了暖棚内热环境又节省了干草储备空间，生态环保，应在高寒草原大力推广。
暖棚夜宿+榦草補飼組閤是我國高寒草原冷季養殖牦牛的重要方式。然而，過于薄弱的圍護結構導緻暖棚夜間的增溫效果僅為6.28℃，而榦草作為一種價廉易得的高效保溫材料，卻需另建囤積空間，故應攷慮如何利用榦草加彊暖棚圍護結構的熱工性能。基于EnergyPlus的模擬計算結果，分析各種榦草保溫措施對暖棚內熱環境及增溫效果的影響，確定閤適的榦草保溫方案，暖棚夜間的增溫效果提高到9.47℃。榦草保溫既提高瞭暖棚內熱環境又節省瞭榦草儲備空間，生態環保，應在高寒草原大力推廣。

The assemble of resting in warm sheds at night&hay feeding is the important way to breed yaks in cold season in severe cold pasturing areas at high latitude in China. However, the too thin envelope induces the warming effect of the shed at night is only 6.28℃, and as a type of cheap, easily-obtained and efficient heat insulation material, hay have to be reserved in other spaces, so how to apply hay to reinforce the thermal performance of sheds’ envelope should be thought about. In this article, based on the simulation results by EnergyPlus, the influences of different hay insulation measures on the shed’s indoor thermal environment and warming effect were analyzed and the appropriate hay insulation plan was determined, which could gain higher warming effect with 9.47℃. Hay insulation can not only improve the indoor thermal environment of warm sheds, but also decrease the space to reserve hays. Therefore, this ecological and environment-friendly strategy should be popularized in severe cold pasturing areas at high latitude.
