防风障是保护地中最简易的设施,可显著减弱风速,减少背风区气热、地热的散失,在干燥、寒冷、多风沙的地区效果尤佳。防风障的桩可用木棍、树枝、竹竿栽插于土埂中,高约2m;披风(笆档)用芦苇、玉米秆、稻麦草等织成,将披风编绑在桩上,基部用土封 Wind barriers are the simplest facilities in the protected area, which can significantly reduce the wind speed, reduce the heat and heat loss in the leeward zone, and dissipate the geothermal energy. It is especially effective in dry, cold and sandy areas. Windproof barrier can be used wood sticks, branches, bamboo planted in the soil 埂, about 2m; cloak (fence file) woven with reeds, corn stalks, rice straw, etc., will be tied to the ponchos on the pile, the base with soil seal
