【摘要】：通過(guò)PHOENICS模擬研究莫高窟窟區(qū)及窟前林帶風(fēng)環(huán)境特征.結(jié)論如下:當(dāng)各風(fēng)向風(fēng)速為最大值時(shí),莫高窟地形地勢(shì)削弱東、西向風(fēng)風(fēng)速,值均大于3 m/s,西南風(fēng)除外;除窟前廣場(chǎng)區(qū)域外,窟區(qū)綠化降低整個(gè)區(qū)域風(fēng)速,部分風(fēng)向降低程度大于1 m/s;窟前廣場(chǎng)背風(fēng)區(qū)域有綠化后風(fēng)速不降反增,東北風(fēng)4 m/s時(shí)72窟窟前風(fēng)速由3.52 m/s增至4.87 m/s:窟前風(fēng)向(0.34)比窟頂風(fēng)向(0.4)穩(wěn)定;風(fēng)速比與來(lái)流風(fēng)速大小無(wú)關(guān),與有無(wú)綠化及風(fēng)向有關(guān),東北風(fēng)無(wú)綠化及有綠化時(shí)分別為1.27和1.08.
[Abstract]:The characteristics of wind environment in the Mogao Grottoes and the fore-forest belt of the grottoes are studied by PHOENICS simulation. The conclusions are as follows: when the wind speed of each wind direction is the maximum, the topography of the Mogao Grottoes weakens the wind speed in the east and west directions, and the wind speed is more than 3 m / s, except for the south-west wind; In addition to the Grottoes Piazza area, greening in the Grottoes area reduces the wind speed in the whole area, and the wind direction decreases by more than 1 m / s; the wind speed increases instead of falling after greening in the Grottoes Piazza Leeward area. The wind speed in front of 72 grottoes increased from 3.52 m / s to 4.87 m / s when the northeast wind was 4 m / s (0.34) was more stable than that of the top wind (0.4), the wind speed ratio was not related to the wind speed of incoming flow, but was related to the greening and direction of greening, and the northeast wind was 1.27 and 1.08 when there was no greening and greening, respectively.
