Fugitive dust has been recognized as an important contributor to air pollution, and artificial porous fence is one of the most effective management strategies to reduce fugitive dust in open areas. To improve the shelter effects and efficiency of Particulate Matter (PM) reduction of traditional fences, this study proposed five bionic fences and their capability was evaluated through wind tunnel tests. The results indicated that all of bionic fences presented better efficiency in reducing wind speed and PM concentrations compared with traditional fences, and they were more efficient in capturing PM₁₀. Among the bionic fences, the non-woven cloth material with four-leave opening presented the best capability both in wind speed and PM reduction. The proposed bionic fences may be further developed and studied for future application in capturing fine PM and adapting to the wind.

生物启发性设计和多孔栅栏用于减轻逃生性粉尘的评估

扬尘已被认为是造成空气污染的重要因素，人造多孔栅栏是减少空旷地区扬尘的最有效管理策略之一。为了提高传统围栏的遮挡效果和减少颗粒物的效率，本研究提出了五种仿生围栏，并通过风洞测试对它们的性能进行了评估。结果表明，与传统围栏相比，所有仿生围栏在降低风速和PM浓度方面均表现出更高的效率，并且在捕获PM ₁₀方面更有效。。在仿生围栏中，具有四叶开口的无纺布材料在风速和降低PM方面均表现出最佳性能。拟议的仿生围栏可能会进一步开发和研究，以用于将来捕获细微PM和适应风的应用。
