By using SWOT Analysis, the internal strengths and weakness, and the external opportunities and challenges of Taohua Mountain Ecotourism Agricultural Park were discussed. The result showed that Taohua Mountain was unique in scenery, rich in rural tourism resources and broad in market prospect. However, the tourism products were monotonous, lack of characteristics and depth; the ecological environment was weak; the tourism staff was with low quality; some parts of the area were in poor sanitary condition, restrained by season and periodicity. Meanwhile, there existed some opportunities and challenges in this park. The opportunities mainly contained policy opportunity and transference of tourists’ preference. The challenges primarily included challenges from urban tourism spots of Ya’an City and surrounding cities, and threats of sustainable use of tourism resources resulting from blind exploitation of fruit production area. And the corresponding development countermeasures were put forward, that is, to develop diversified tourism programs, to allocate mountainous resources according to local conditions, to train the local tourism staff, to dredge the area with poor sanitation, to diversify business with other industries supporting the development of tourism agriculture. 展开更多

Ecosystem responses to climate change,particularly in arid environments,is an understudied topic.This study conducted a spatial analysis of ecosystem responses to short-term variability in temperature,precipitation,and solar radiation in the Qilian Mountains National Park,an arid mountainous region in Northwest China.We collected precipitation and temperature data from the National Science and Technology Infrastructure Platform,solar radiation data from the China Meteorological Forcing Dataset,and vegetation cover remote-sensing data from the Moderate Resolution Imaging Spectroradiometer.We used the vegetation sensitivity index to identify areas sensitive to climate change and to determine which climatic factors were significant in this regard.The findings revealed a high degree of heterogeneity and non-linearity of ecosystem responses to climate change.Four types of heterogeneity were identified:longitude,altitude,ecosystem,and climate disturbance.Furthermore,the characteristics of nonlinear ecosystem responses to climate change included:(1)inconsistency in the controlling climatic factors for the same ecosystems in different geographical settings;(2)the interaction between different climatic factors results in varying weights that affect ecosystem stability and makes them difficult to determine;and(3)the hysteresis effect of vegetation increases the uncertainty of ecosystem responses to climate change.The findings are significant because they highlight the complexity of ecosystem responses to climate change.Furthermore,the identification of areas that are particularly sensitive to climate change and the influencing factors has important implications for predicting and managing the impacts of climate change on ecosystems,which can help protect the stability of ecosystems in the Qilian Mountains National Park. 展开更多

Increasing use on mountain summits has both social and ecological implications.High numbers of visitors climbing mountain summits can be a safety issue,particularly in areas where terrain or elevation leads to queueing that may cause time delays.Estimating visitor use levels at site specific locations en route to summits is needed to understand the potential benefits and impacts of visitor use in these locations.However,it can be difficult to obtain reliable and robust data to estimate use and develop statistical relationships because of the remote and harsh climates on mountain summits,as well as the financial and personnel requirements involved to collect the data in remote locations.In 2015,data were collected on the higher stretches of the Keyhole Route on Longs Peak in Rocky Mountain National Park,USA(RMNP)to better understand use levels near the summit and to explore potential statistical relationships to trailhead use data that are relatively easy to collect.Strong statistical relationships from robust regression analyses were found between trailhead use counts and daily and hourly use totals on the"Homestretch"which is a final section of the Keyhole Route.Additionally,a strong statistical relationship was found between total daily use and maximum hourly use on the Homestretch.The results suggest that trailhead counts are an accurate and reliable means from which to estimate use levels on upper portions of the Keyhole route.Moreover,this research demonstrates the usefulness of an approach using proxy variables to estimate visitor use along remote peaks where data collection can be difficult.These types of data can elucidate various options and decisions for park management teams who are charged with deciding if and how to manage high use areas. 展开更多

Previous work on the eastern side of Rocky Mountain National Park(RMNP),Colorado indicated correlations among waterfall location,waterfall morphology,and the characteristics of bedrock joints.Characteristics of waterfalls on the western side of the national park do not correlate as strongly with joint geometry.Longitudinal river profiles on the western side are less concave and waterfalls account for a greater proportion of the total elevation loss.We interpret these differences to result from more widely spaced joints,lithological differences,and complex glacial history.These results demonstrate that waterfall shape and typology may change due to both local and regional controls operating in a mountain region.Both regions had alpine valley glaciers,but continued landscape evolution via fluvial erosion has developed waterfalls with diverse locations and morphologies that reflect the influences of glacial deposits,bedrock erosional resistance,and joint geometry. 展开更多

This paper compares the views and attitudes of visitors to three key mountain national parks and Biosphere Reserves: Sumava National Park (Sumava NP, Czech Republic), Krkonose National Park (KRNAP, Czech Republic) and Karkonoski Park Narodowy (KPN, Poland). A large numbers of people visit these destinations both in the summer (e.g. hikers and cyclists) and in the winter (e.g. hikers and skiers), which threatens sustainability and creates problems regarding the management of these areas. A comprehensive understanding of visitor use, including visitors’ attitudes and perceptions, is fundamental for effective park management. Most research in these national parks is carried out during the summer season, therefore different results in the winter season are expected. Using a standardised socio-environmental survey we attempt to find seasonal differences between visitors and their opinions. A total of 2252 questionnaires were gathered. There were 13 common questions for these three national parks, three of them yielded significantly different results between the two seasons (visitors’ nationality, type of accommodation and financial costs). Other differences were detected in one or two national parks. 展开更多

Together with the main aim of preserving nature,national parks are also expected to play an important role for the local communities,driving economic activities toward the lens of sustainable development.This contribution aims to present an exploratory study on the relationship between the presence of a protected mountain area,the Gran Paradiso National Park(GPNP),in the North West of the Italian Alps,and the classification of tourism destinations,according to Weaver model of destination management.Starting from the model,the authors provide a quantitative analysis using a set of variables and indicators to comprehensively assess the differing patterns assumed by the municipalities within the borders of the GPNP and those that are not.The provisional results illustrate that the municipalities within the border of a protected area are more likely to be grouped alongside the sustainable mountain destinations.Meanwhile,research outcomes confirm that a protected area does not necessarily contrast the tourism industry but instead may boost local development by driving it within the borders of the sustainable development,switching from the area’s only preservation function to a flywheel for the local communities. 展开更多
