松潘黄龙钙华演化趋势研究

Evolutionary Trend of the Huanglong Travertine in Songpan

黄龙主沟露天钙华分布面积为634 712m2,最大厚度为19.72m。在3.5万年以来的演化过程中形成了绚丽多姿的钙华彩池、钙华滩流、钙华瀑布、钙华洞穴等景观。它被誉为"人间瑶池",是世界著名的旅游胜地。其中钙华彩池105 932m2,钙华滩流157 882m2。根据钙华在演变过程中所处的阶段可划分为成长区、平衡区、消退区、非沉积区等4个演化分区。钙华景观的发展演化不由其形成时代的新老决定,而与自身所处的地质背景、水循环系统控制下的钙华源泉的稳定性密切相关。目前,黄龙钙华景观主体处于青壮年期。

Huanglong is world-famous tourist scenic spot.The Hunaglong travertine consists of gorgeous travertine color pools,travertine beach,travertine falls and travertine caves which were formed during the past 35000 years and famed as 'abode of immortals in the human world'.The area of the Huanglong travertine is 634712 km2 with color pools of 105932 m2 and beach of 157882 m2.The largest thickness is 19.72 m.According to the evolutionary history,the travertine may be divided into 4 districts: growing area,balance area,degeneration area and nondepositional area.The development of the travertine is related to the geological setting and stability of travertine source spring.At present,the travertine landscape is mostly in stage of maturity.
