中文摘要	通过PHOENICS模拟研究莫高窟窟区及窟前林带风环境特征.结论如下:当各风向风速为最大值时,莫高窟地形地势削弱东、西向风风速,值均大于3m/S,西南风除外;除窟前广场区域外,窟区绿化降低整个区域风速,部分风向降低程度大于1 m/s;窟前广场背风区域有绿化后风速不降反增,东北风4 m/s时72窟窟前风速由3.52 m/s增至4.87 m/s;窟前风向(0.34)比窟顶风向(0.4)稳定;风速比与来流风速大小无关,与有无绿化及风向有关,东北风无绿化及有绿化时分别为1.27和1.08.
英文摘要	According to the simulation of Mogao Grottoes by software of PHOENICS, this paper comparatively studies the wind environment of the whole green area of and that in front of the forest belt. The results of simulation comparison are as follows. The block effects to the directions with east and west wind were more than 3 m/s when each direction wind has the maximum wind speed, except the southwest wind. Greening in the whole area reduces the wind speed to about 1 m/s. The velocity of wind in some leeward area increases but not decreases. The wind speed 4 m/s in the northeast direction in front of No. 72 grottoes increases from 3.52 m/s to 4.87 m/s. Wind direction change rate in front of grottoes is lower than the one above grottoes. The former is 0.34, and the latter is 0.40. Wind speed rationever change with the numerical size of velocity, but change whether with greening or wind direction. The of greening and non-greening are 1.27 and 1.08.
