| Abstract | 為了降低莫高窟壁畫由于賦存環境改變而引發病害深度惡化的風險,本文選取2011年8月-2012年8月間的監測數據,分析在突發性強降雨條件下,崖體同層、大小與形制相似的開放洞窟和不開放洞窟微環境的變化規律及差異性。研究表明,強降雨對窟內溫度影響較小,但相對濕度出現了較大波動,具有時間滯后性。開放洞窟和不開放洞窟相比,相對濕度波動頻率更明顯,滯后時間均為10小時,要持續7小時才可達到另一種相對穩定的狀態。本研究結果有助于洞窟管理者及調度人員合理安排洞窟排查時間及游客參觀時間,并為決策者制訂及時有效的防范措施提供理論依據。
In order to reduce the risk of severe deterioration in the Mogao Grottoes murals caused by unexpected environmental changes,the monitoring data from August 2011 to August 2012 were selected to analyze the regular patterns and differences of the micro-environments of caves under sudden rainfall vis-à-vis open caves and closed caves of similar size and shape situated on the same level of the cliff.The research results show that rainfall has little influence on the temperature inside the caves,but the relative humidity fluctuates obviously with a time-lag effect.Comparing the open caves with closed caves,the fluctuation frequency of relative humidity seems to be more obvious with the same lag time of 10 hours.It has to last for seven hours before reaching another relatively stable state.Therefore,the results provide evidence for a reasonable cave checking and visiting schedule.Meanwhile,this paper provides a theoretical basis for decision-makers to establish effective preventive measures in a timely manner. |
