| The Impact of Tourist Activities on PO43- Concentrations and Aquatic Algae Growth at the Huanglong Scenic Spot, Sichuan Province |
| The Huanglong scenic spot, well known for its unique natural landscape, was listed by UNESCO in 1992 as an entry in the World’s Nature Heritage, and has attracted tens of thousands of tourists from various counties of the world every year. Due probably to the impact of tourist activities in recent years, Huanglong travertine landscape has shown serious degradations, one of which is the accelerated algae propagation and travertine darkness. To understand whether this degradation has relation with tourist activities, the authors used automatic logging in field combined with laboratory analysis in the wet period of 2010 from late May to early November to study temporal variations in algae chlorophyll concentration and phosphate concentration in stream water. The results show that, with the increase or decrease of tourist number, the phosphate concentration shows the same change trend, and so does the chlorophyll concentration. Therefore, it is concluded that the tourist activities have affected the phosphate concentration in Huanglong stream water, and the latter promotes the algae growth. This may be the main reason why algae has shown accelerated growth in recent years. |
