In order to ensure that the control method and control variable of the caves will not damage the murals and statues to any degree,CFD technology was used to analyze the control means of the cave’s micro environment.The analysis results show that active ventilation creates lower pressure and mural surface wind speed than active air supply.The air exchange experiment in cave 131 confirms the results of CFD analysis.It can thus be concluded that using the active ventilation control method in smaller caves is effective in reducing air humidity and decreasing the concentration of carbon dioxide,lessening the influence on the cultural relics in the caves.
