拉萨地区民居是在高原寒冷干燥气候条件下形成的一种特殊的居住形态.随着时代的发展,大量新式民居已逐步开始替代传统民居,其围护结构及建筑材料的使用也有较大差异,与传统民居相比,新式民居在围护结构热工性能及室内热环境方面的变化是值得关注的问题.本文选取拉萨赤角林村传统民居和新式民居进行了冬季室内热环境参数实测和计算机模拟,比较了2类民居的室内热环境及围护结构热工性能,分析了新式民居室内热环境的变化与特点,为该地区民居室内热环境的改善和对比研究提供量化依据.%Traditional rural dwellings in Lhasa is a special building type which is come into being according to local climatic characteristics. With the society development, modern rural dwellings gradually began to replace the traditional one. Comparing with the traditional rural dwellings, the changes of building envelope thermal performance and indoor thermal environment of modern rural dwellings should be paid more attention. In this paper,the modern and traditional rural buildings in Chijiaolin village were selected to carry out the measurement and simulation study. Based on the comparison of these two dwellings' building envelope thermal performance and indoor thermal environment, the changes and characteristics of the modern one were analyzed. The conclusions could provide references for improving the indoor thermal environment of rural dwellings in Lhasa.
