Abstract: According to the scientific theory and logic of biological evolution, this paper analyzed the evolution strategy selection of anti-erosion wear of the desert lizard, and proposed that wind was the major factor and main contradiction of anti-erosive wear. On the basis of the typical pit form extracted from the desert lizard’ s skin, the combined method of numerical simulation and theoretical analysis were used to analyzed the air flow field form of pit surface and explained the anti-erosion wear mechanism of bionic pit form, and also supplemented the anti-erosion wear evolution strategy of desert lizards, which provided a theoretical reference for the engineering bionic design.
