摘　　要：秦巴山区地处夏热冬冷地区北部高纬度区域,建筑冬季室内热环境恶劣,提高和改善室内热环境质量对建设可持续发展的乡村人居环境具有重要意义.以位于秦巴山区腹地的汉中为例,依据标准气象数据资料,确定汉中乡村建筑围护结构传热系数的修正系数,通过对比分析建筑窗墙比、围护结构传热系数等参数对建筑耗热量的影响,研究乡村建筑构造热工性能及其优化设计方案,并做出相应的经济技术分析.结果表明,建筑热工优化后,屋面传热耗热量由38.92W/m^2减少到6.53W/m^2,墙体传热耗热量由16.72W/m^2减少到4.83W/m^2,有效地降低了冬季建筑耗热量,明显改善了该地区乡村建筑冬季室内热环境质量,且建筑热工优化前后的成本相差不大.该优化方案在秦巴山区乡村具有可行性,可为该地区乡村建筑的设计提供参考.Qinba mountain area is located in the high northern latitudes of the hot summer and cold winter zone,and the indoor thermal environment of the residences is harsh.Enhancing and improving the indoor environmental quality has an important significance on the construction of human settlements.Taking Hanzhong located in the hinterland of Qinba Mountain Area as an example,the correction coefficient of envelope heat transmission coefficient of building envelope in Hanzhong is determined according to the standard meteorological data.According to analysis affected by the parameters of window-wall ration,heat transmission coefficient of envelope,an optimal design for the architecture thermal performance is carried out,and the economic-technology analysis is made as well.The results show that through the optimal design of envelope,the consumption value of heat transmission on the roof decreases from 38.92 W/m^2 to 6.53 W/m^2,and the consumption value of heat transmission of exterior wall decreases from 16.72 W/m^2 to 4.83 W/m^2.The architecture heat consumption is reduced and the indoor thermal comfort of the rural architecture in winter in the region is improved,and there is little difference in cost before and after thermal optimization.The optimization scheme is feasible in Qinba Mountainous Area,and can provide references for the design of rural architecture in this area.
