摘　　要：通过FLUENT软件模拟对比研究乔木的遮阴作用对莫高窟热环境的影响。结论如下:三维乔木阴影区的空气温度较低,背风区域出现高温;三维乔木的遮阴作用仅对局地热环境产生影响,而对窟区整体的热环境及热岛强度影响微弱;通过调整窟区绿化的种植密度,能够改善甚至消除窟区背风区域的高热环境。This paper used the software of Fluent to simulate thermal environment with or without shading effect. The conclusions are as follows. The air temperature of three-dimensional tree is low, but the air temperature of leeward area is high. The shading effect of three-dimensional trees works only for geothermal environment, but works little for the whole area of thermal environment and heat island intensity. Through the adjustment of the planting density in the area of greening, can we improve and even eliminate the heat environment in the leeward area.
