This paper uses the travel cost method to estimate the recreational value of the glacier tourism resources of Yulong Snow Mountain(also called Jade Dragon Snow Mountain), which is the most developed glacier tourist attraction in China. First-hand information was obtained through field surveys, and the travel costs of visitors visiting the Yulong Snow Mountain glacier were calculated before the method was applied to evaluate the recreational value of the focal glacier resource. The results show that the Yulong Snow Mountain consumer surplus associated with its glacier resources in 2016 ranged from 645.59-3439.10 million CNY, and the total recreational value ranged from 1.97-8.17 billion CNY. Approaches allocating travel costs across multiple recreational sites, however, can vary, and there is large difference in estimated results depending on used approaches. Nevertheless, the results of the analysis can help understand the socio-economic value of glacier resources and provide a reference for their development and protection.展开更多

The pH of summer rainfall at Lijiang City ranges from 6.7 to 7.4, and alkaline mineral salts dominate the variations of rainfall acidity, pH values in the shallow firn profile at Baishui （白水） Glacier No. 1 range from 5.6 to 6.3, and EC values from 2.4 to 7.3 μs/cm. The ranges are lower than those in other firn cores from China because of stronger elution and the influence of marine aerosols. This indicates that environmental records from a monsoonal temperate glacier differ from those at continental glaciers.展开更多

This fault is called eastern piedmont fault of Haba-Yulong Snow Mountains (HYPF). The fault consists of two segments with differential trend; the northern segment is NW-trending and NE-dipping and the southern section is S-N trending and E-dipping. Three sets of fault scarps cutting late Quaternary landforms and their dating results indicate that the fault is a prominent Holocene active fault and its throw rates are 0.3―1.4 mm/a during late Quaternary. The geometry and kinematics of the fault suggest that the arcuate normal faulting or rifting are typical surface deformation pattern at the two tips of the Z-shaped rift zone of northwestern Yunnan, which is related to regional east-west extension accompanying clockwise rota- tion of micro-block.展开更多
