根据生物进化的科学理论和逻辑，分析了沙漠蜥蜴抗风沙冲蚀磨损的进化策略选择，并提出了风是风沙冲蚀磨损的主要因素和研究风沙冲蚀的主要矛盾点。在仿沙漠蜥蜴体表形态提取的典型凹坑形态的基础上，采用数值模拟和理论分析相结合的方法，分析了具有凹坑形态表面的空气流场形式，解释了仿生凹坑形态抗冲蚀磨损的机理，补充了沙漠蜥蜴抗风沙冲蚀的进化策略，为工程仿生设计提供了理论参考。
根據生物進化的科學理論和邏輯，分析瞭沙漠蜥蜴抗風沙遲蝕磨損的進化策略選擇，併提齣瞭風是風沙遲蝕磨損的主要因素和研究風沙遲蝕的主要矛盾點。在倣沙漠蜥蜴體錶形態提取的典型凹坑形態的基礎上，採用數值模擬和理論分析相結閤的方法，分析瞭具有凹坑形態錶麵的空氣流場形式，解釋瞭倣生凹坑形態抗遲蝕磨損的機理，補充瞭沙漠蜥蜴抗風沙遲蝕的進化策略，為工程倣生設計提供瞭理論參攷。

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.
