Even in protected areas, it is inevitable that any human use will produce some impact on natural resources. This study identifies visitors’ tolerance of potential negative ecological impacts from tourism activities and facilities in a Norwegian national park context, based on park visitors’ expressed degree of acceptance of negative effects on particular species of wildlife (wild reindeer and raptors) and on vegetation. Attitudes were analysed using psychographic scales, reflecting respondents’ nature orientations, their specific facility desires, their preferences in a wilderness setting and their concerns about human interaction with the natural environment. Fourteen research hypotheses were tested. Findings demonstrated that the psychographic scales explained more variation in attitudes than most social background and trip characteristics. Higher levels of education among visitors were strongly associated with increased ecological concern; age and gender were not. There was generally strong ecological awareness and eco-centrism among park visitors in general, with a small proportion of wilderness purists. Better trail conditions, signposting and interpretation were sought. But park visitors were also found to possess a complex mixture of needs and drivers. The study found significant potential for strategic alliances between tourism and conservation interests, and key value issues for park governance systems. 相似文献

The Carpathian Basin is one of the most vulnerable European regions in terms of potential climate change impacts on biodiversity. Its wide range of tourism activities make it uniquely suitable for assessing the effects of climate change on tourism. This research sought to create a Tourism Adaptation Portfolio (TAP) for the Szentendre micro-region in Hungary and to assemble an adaptation toolbox for current and future use by tourism organizations. The TAP contains practical, easy to implement solutions for key stakeholders in the sector by adaptation type (technology, management, behavior, education, policy). Surveys of local tourism suppliers showed that 70% said they were well informed, largely by the Internet, but 55% admitted to not knowing enough. The methodology outlined here is transferable and the process can be replicated elsewhere, supporting other regions in becoming climate-friendly tourism destinations, creating opportunities for uniquely positioning a region for consumers. The article provides a concise overview of tourism provider attitudes assessed through a questionnaire, shedding light on points of intervention, willingness to pay, main barriers and suitable adaptation instruments. The adaptive capacity of stakeholders is also discussed, which is indispensable for implementing successful practices in adaptation and maintaining the current level of environmental services. 相似文献

Tourism crowding management is an important part of sustainable development at tourist attractions. This study seeks to recognize visitors' perceptions of crowding and then identify tourism crowding management approaches for tourism sites in Xi'an, western China. Three kinds of study, which were designed using quantitative and qualitative techniques, were undertaken in Xi'an. In the first two studies the actual numbers of visitors at component parts of five tourist attractions were recorded. Next, visitor responses to these kinds of levels of crowding were assessed. In the third study senior managers were interviewed and asked to explain their approaches to crowding management. Taken together, the information collected from the three studies helped build a model that plots the driving forces shaping tourism crowding at tourism sites. 相似文献

World Heritage Sites (WHS) are often popular and primary attractions for a destination for many reasons, in particular the economic benefits they bring in terms of increased visitation and extension of stay. However, without active management to reduce negative impacts, such as congestion, both tourists and the host community can become caught up in a downward spiral of poor visitor experiences and degradation of World Heritage values. Accordingly, this paper examines the nature of congestion and its impact on visitor experience at two popular WHS attractions in Macao. It also provides some insights into Chinese outbound tourist behaviour and visitation patterns. These observations should be of interest to planners and site managers of popular World Heritage attractions elsewhere in the world as China begins to adopt mass international leisure travel. 相似文献

In this paper we investigate how restaurant managements’ attitudes and behaviors influence decisions to purchase local foods as inputs to their products. An enhanced investigation of chefs’ and managers’ decision-making criteria could improve understanding of local food systems linkages with the restaurant industry. We apply a value chain framework to investigate activities that influence restaurants’ decision to purchase local foods. Results indicate that attitudes and behaviors associated with sourcing and product characteristics play an important role in local food purchase decisions in the restaurant value chain. Order processing time and uniqueness of products are the most significant reasons in restaurant managements’ decisions to purchase local foods. The implications of these findings for restaurants and producers are discussed. Our study contributes to the literature by expanding upon the criteria used by restaurants to make local food purchasing decisions. 相似文献

This paper explores a game-theoretically founded approach to conjoint analysis that determines equilibrium room rates under differentiated price competition in an oligopolistic hotel market. Competition between hotels is specified in terms of market share functions that can be estimated using multinomial logit models of consumer choice. The approach is based on choice-based conjoint analysis that permits the estimation of attributes weights (“part-worths”) for an additive utility formulation of the utility function. From this, room rates that equilibrate the market, conditioned on the differences in services and facilities offered by competing hotels, can be determined. The approach is illustrated by an example. 相似文献

Indirect non-lethal effects of wildlife tourism have the potential to compromise the long-term health of animal populations. While appropriate management of impacts is clearly necessary, such management is rarely reported to be effective. Doubtful Sound (New Zealand) has boat-based scenic cruises running year-round. This fjord is also home to an endangered population of bottlenose dolphins, a natural asset for the local tourism industry. A voluntary code of management (COM) was implemented in 2008 to alleviate vessel impacts, establishing guidelines to leave dolphin encounters to chance and restricting vessel traffic in areas of critical habitat. The frequency and duration of interactions decreased substantially since the implementation of the COM. This evidence shows that a science-based voluntary agreement has the potential to mitigate tourism impacts. Nevertheless, due to the small size of the population and its history of low calf survival, a precautionary approach is necessary to further reduce current anthropogenic impacts. 相似文献

This study aims to develop a measurement scale for organizational career management (OCM) in China's hotel industry. The scale development procedure includes four steps: developing initial items, implementing purifying measures, data collection, and assessing the reliability and validity of the proposed measurement scale. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are used to test the reliability and validity of the measurement scale thus developed. The development process results in a reliable and valid scale for hotel career management incorporating three dimensions: (1) career appraisal and advice, (2) a career development program, and (3) career training. Given the scarcity of research on career management in China, the measurement scale developed in this study will serve as a foundation for future research. The findings of this study may help to stimulate further empirical research on the relationship between hotel career management and employees’ career commitment and career satisfaction. 相似文献
