边陲新疆,多大风区,多大风口。当你乘坐去新疆的火车,总会看到在铁路沿线有多种形式的挡风墙,或水泥墙,或土墙,或用旧枕木筑起的木墙,这是挡风用的。这要比在内地植一行树的代价高,新疆干旱多风,唐时就有“轮台九月夜风吼,一川碎石大如斗,随风满地石乱走”的诗句。 Xinjiang border, how big wind area, how much tuyere. When you take a train to Xinjiang, you will always find various types of wind walls, or concrete walls, or earth walls, or wooden walls built of old sleepers along the railway. This is for windshield use. This is more costly than planting trees in the hinterland. When there is arid and windy weather in Xinjiang, there is a poem in the Tang Dynasty such as “the night roar of September at the Taiwan Strait, the unification of the shrubs in the Chuanchuan, the chaos of the rocks everywhere”.
