Taking the Loess Plateau as the research area, using the theory and method of the settlement landscape gene, the landscape gene of the cave building was identified and the variation of the gene was analyzed. Following the inherent uniqueness principle, the external uniqueness principle, the local uniqueness principle and the general superiority principle, the cave landscape gene elements are decomposed into four aspects such as the facet form gene, the plane layout gene, the building material gene, the local decoration gene and so on. The arch kiln face is the main symbolic feature of cave dwe...
