| The Impact of Tourist Activities on Hydrochemistry and Travertine Deposition Rate at Huanglong, Sichuan Province |
| Huanglong, well known for its unique travertine landscape, was listed by UNESCO in 1992 as an entry in The World’s Nature Heritage and, since then, has attracted tens of thousands of tourists from all over the world each year. Maybe due to the impact of tourist activities in recent years, Huanglong travertine landscape has shown serious degradations, one of which is the declined travertine deposition rate. To understand whether this degradation has relation with tourist activities or not, the authors used water sampling combined with laboratory analysis in the wet period of 2010 from late May to early November to study temporal variations in concentrations of phosphate and dissolved organic carbon (DOC) in stream water and in travertine deposition rate. The results indicated that, with the increase/decrease of tourist number, the concentrations of phosphate and DOC showed the same variation trend, and the negative correlation was found between travertine deposition rate and concentrations of phosphate and DOC, especially at Wucaichi and Yingbinchi sampling sites. Therefore, it is concluded that the tourist activities have affected concentrations of both the phosphate and DOC in Huanglong stream water, the latter inhibiting travertine deposition rate. This may be the main reason why the travertine deposition rate has declined in recent years. |
