Özet
The factors of slow degradation of travertine in Pamukkale Turkey were discussed by comparing the basic environmental geological characteristics，hydrochemistry of travertine landscape，and biological factors of travertine sedimentation in Huanglong，Sichuan，Baishuitai，Yunnan，China，and Pamukkale，Denizli，Turkey. The results showed the species of algae in Pamukkale was single with about 38 species，and the vegetation coverage rate was low. Besides，travertine deposition was mainly controlled by abiotic factors，and the deposition rate was relatively high. Travertine had a good layered structure，low primary porosity and compact structure，so it was not easy to collapse and damage. However，the species of algae in Huanglong and Baishuitai were diverse with about 86 and 196 species，respectively. And both vegetation coverage rates were above 80%. Travertine deposition was mainly controlled by biological factors with the low-rate deposition，the porous structure，the loose or porous coral-like and the high primary porosity，resulting in easy degradation Besides，the contents of ions in the spring water of Pamukkale travertine were higher than that of Huanglong and Baishuitai travertine，especially Ca2+ and HCO-3，which could effectively promote the deposition of CaCO3 © 2021 Institute of Karst Geology of Chinese Academy of Geology Sciences.
