Preliminary Investigation on Destruction of Tibetan Willow Resources by Making Prayer Flags in Tibetan Areas
Prayer flags can be found on the roofs of Tibetan houses and are replaced every year as a symbol of good fortune.According to survey,in Lhasa,Shannan and Shigatse,on every year Tibetan New Year,weddings and funerals,major festivals,every family will hang prayer flags on the roof.The trees that hang prayer flags are generally willow trees in Tibetan areas,which were cut from the willow mother tree with slender branches 4～5 m in height and 8～10 cm in diameter.Every year,a large number of trees are cut down in a disorderly manner in Tibetan areas to make prayer flags,which causes extreme damage to the vegetation and living environment of Tibet.Forest vegetation in Tibet is sparse and its growth is slow.Every household replaces prayer flags with a large number of willow trees,which seriously damages the ecological environment of Tibet,resulting in fre-quent natural disasters such as mudslides,landslides,soil erosion and snowstorms.Desertification is threatening the ecological environment of Tibet.In this paper,the author takes 15 administrative villages of Luojiang Town in Bailang County as the investigation area,and makes investigation and analysis on making prayer flags and cutting down trees in Tibetan areas every year,and gives corresponding countermeasures.
