Why Has the Great Wall Preserved So Well The Great Wall,a symbol of ancient civilization,stretches across northern China.Despite its grandeur,(1) remains today is only a part of its former self,due to the wear and damage caused by time and nature. However,a recent discovery reveals that nature(2) might be playing a crucial role in preserving this historical wonder.Thin layers of bacteria and other organisms,known as biocrusts, have been considered (3) (protect)sections of the Great Wall,sheltering it from wind and rain,and other destructive elements. A study published in Science Advances highlights the significant role these "living skins"play in conserving this ancient architectural marvel.(4) advances in technology and research, scientists are now exploring the potential of cultivating new biocrusts to prevent further degradation of the Wall. Nichole Barger,an ecologist,praises the study as "innovative and creative",noting that the protective effects of biocrusts (5) (gain)increasing recognition in recent years.It is acknowledged that dryland ecosystems (6) (stabilize)and soil ero.sion(侵蚀)is prevented by these biological layers. (7) the more famous sections of the Great Wall are constructed from stones or bricks,other parts were built using packed soil.Yet,the same packed soils can also host biocrusts,(8) cover about 12%of the Earth's land surface,particularly in dry regions like northern China.These biocrusts vary in form,(9) (range)from thin bacterial networks to thicker layers of lichen(青苔). Soil scientist Bo Xiao from the China Agricultural University,along with his colleagues, conducted a study to investigate the role of biocrusts in preserving the Great Wall.Their research revealed that biocrusts,primarily(10)(compose)of moss or bacteria,covered more than two-thirds of the Wall's surface in the areas they examined.By studying the physical properties,they made a significant discovery.
