    Abstract: 隨著科技發展、醫學進步,人口逐漸現象,但在有限的土地上求生活空間,所以建築物有向上發展的趨勢,加上政府近年來推動都市更新的計畫,都市中存在著越來越多的高層建築。
    Before, we only have three typical terrain’s roughness blocks. If we want to know a real topography’s wind feature, we have to make a reduced scale’s model to simulate it. But it will be waste human resources and spend a lot of time and money. So if we can find some way to use roughness blocks to simulate the real topography, it will be more efficiently. On the other hand, in the field measurement we can’t got the information of the turbulence. If we successfully use the way to simulate terrain, we can got more information of terrain.
    The results show that we can use the mean height of the build and density of the terrain to simulate the real topography. In roughness block’s experiment, we successfully simulate the wind profile, turbulence intensity and turbulence length scale.
