摘　　要：通过对比、分析滇西北香格里拉1981-2010年气象数据,以十年为一阶段划分比较,调查火灾后的独克宗古城,结合古城的地形、地貌特征,研究独克宗古城火灾的外部火环境。结果表明香格里拉冬季温度低,降水量少,但蒸发量大,空气很干燥,可燃物特别容易着火。风速大,有利于火灾扩散,但不利于灭火,要加强冬季火灾的预防。Through analysis and contrast of the meteorological data in 1981--2010 in Shangri La,northwest Yunnan, taking 10 a for a stage division,investigated Dukezong city after fire, combined with the topography and geomorphology study,the exter nal fire environment was researched. The results showed that Shangri-La in winter,it is of low temperature, less precipitati on, but the large amount of evaporation, and dry air, so corn bustibles are easy to catch fire;at the same time, with the big wind speed, fire spread is more easily while fire fighting is hard so fire prevention in winter should be pay more attention to.
