莫高窟地区降水变化特征分析

Characteristics in Precipitation Variations over Mogao Caves

莫高窟是被国务院首批列为全国重点文物保护单位,也是世界文化遗产之一。暴雨引发的洪涝灾害对莫高窟的保护带来巨大的威胁,因此研究莫高窟及其周边地区的降水特征具有重要意义。利用大泉河流域上游的肃北和下游的敦煌气象站的地面降水观测数据分析了莫高窟及周边地区的降水变化特征。

Mogao Caves is listed as the first national key cultural relics conservation unit by the State Council and is also one of the world cultural heritages. The flood disaster caused by heavy rain brings great threat to the protection of Mogao Caves, so it is of great significance to study the characteristics of precipitation in and around Mogao Caves. In this paper, the long-term surface precipitation observation data at two meteorological stations, Dunhuang and Subei along the Daquan River Basin, are used to analyze the characteristics of precipitation variation in and around Mogao Caves.
