摘要
对不同类型的林带,分别模拟它们的宽高比在0.25、1、3、5、7、10、15下的绕林流场,分析比较了带后相对速度的变化情况。除宽度外其它条件基本相近的情况下窄林带比宽林带的防护效应好,而且当宽高比小于5时,其对林带防护效应影响较大,而当宽高比大于5时,影响较小。
The paper simulates the flow fields through shelter belt with different ratio of width to height, such as 0.25, 1, 3, 5, 7, 10 and 15, and compares the change of relative velocity in the horizontal level, In the other same conditions, the narrower shelter belt provides more effective protection and the width of belt has more effect on the protection when the ration is lower than 5.
