In the critical period of the transformation of China's construction mode,the light prefabricated construction system has shown a vigorous development trend.Combined with multiple influencing factors such as"geography,climate and culture",this paper takes residential buildings as an example,aims at the regional creation problems of light prefabricated buildings in northern Tibet,and summarises three key points:"inner inheritance of traditional Tibetan architecture construction culture","local translation and application of light prefabricated building system",and"innovation and reconstruction under new materials and new technologies".From"meaning"to"form",it is expected to provide reference for the local creation of light prefabricated buildings in northern Tibet.
