It aims to provide sustainable benefits for future generations, while protect the property and minimize the possible adverse social, economic and environmental impacts. Indicators of sustainable development, which summarize information for decision-making, are invaluable to learn the efficiency and effectiveness of property management. Scientists in many fields devised several conceptual models of environmental statistics and indicators, of which, DPSIR (Driving forces – Pressure – State – Impact – Response) is thought to be the best available one in identifying and developing indicators of sustainable development. Based on the DPSIR conceptual model and indicator selection criteria, the present paper proposed a methodology framework for selecting indicators to assess the sustainable development of a natural heritage site. The proposed framework included a multi-level hierarchical structure for various indicators and indexes, a modified DPSIR frame to identify key issues in property management and a set of indicators for evaluating the sustainability in Sichuan Giant Panda Sanctuaries.展开更多

Measuring the recreational value of world heritage sites is a key issue in the heritage tourism. This paper employs Contingent Valuation Method (CVM), which is an evaluation instrument on the basis of tourists′ attitude and preference, to measure the recreational value of Jiuzhaigou, one of the World Natural Heritage sites in China, and analyzes the biases in the survey. The results show that: 1) In 2009, Jiuzhaigou′s recreational value was 3.46×108 yuan (RMB), and the per capita Willingness to Pay (WTP) was 137.31 yuan by CVM. Compared with the results of other methods, this result is significantly low. 2) Among the factors that influence Jiuzhaigou tourists′ WTP, psychological perception factors have the greatest effect while demographic and socio-economic characteristics have a small effect on WTP. 3) The virtuality in CVM creates biases both from CVM itself and in the procedures that CVM was implemented. The former includes hypothetical bias, information bias, protest response bias, and strategic bias; and the latter includes the questionnaire design, population and sample definition, sampling and data processing. The paper analyses those biases and illustrates their potential in-fluences on the accuracy of CVM measurement. 4) Although there are various defects in CVM measurement, it is still an effective valuation method.展开更多

However, available data and a generally accepted protocol on such measurement are still limited. This study uses water footprint accounting to quantify tourist’s water demand in the Liming valley, a World Heritage site and a rapidly growing tourism destination in Northwest Yunnan, China. Both the water for direct and indirect use is taken into account based on the consumptive behavior of the tourists in the valley. Data were collected through guesthouse monitoring and a tourist survey in the 2005 tourist season. The results indicate that an average tourist leaves behind a footprint of 5.2 m3 on local water resources per day. Food production and waste dilution are the two most important water consumption factors. The results also show tourists consume more water than the local residents on per capita basis. This suggests more commitment is necessary to cope with this stress by individual tourists. Management implications to make water use more sustainable in mountain destinations are derived from this study.展开更多

Jiuzhaigou Valley is an area recognized and listed as a world heritage site by UNESCO in 1992. Data analysis and field survey were conducted on the landslide, collapse, and debris flow gully, to assess the coseismic geological hazards generated by the earthquake using an unmanned aerial vehicle(UAV), remote-sensing imaging, laser range finders, geological radars, and cameras. The results highlighted the occurrence of 13 landslides, 70 collapses, and 25 potential debris flow gullies following the earthquake. The hazards were classified on the basis of their size and the potential property loss attributable to them. Consequently, 14 large-scale hazards, 30 medium-sized hazards, and 64 small hazards accounting for 13%, 28%, and 59% of the total hazards, respectively, were identified. Based on the variation tendency of the geological hazards that ensued in areas affected by the Kanto earthquake(Japan), Chi-chi earthquake(Taiwan China), and Wenchuan earthquake(Sichuan China), the study predicts that, depending on the rain intensity cycle, the duration of geological hazard activities in the Jiuzhaigou Valley may last over ten years and will gradually decrease for the following five to ten yearsbefore returning to pre-earthquake levels. Thus,necessary monitoring and early warning systems must be implemented to ensure the safety of residents,workers and tourists during the construction of engineering projects and reopening of scenic sites to the public.展开更多

The number of travellers and traveller's tales greatly increased after the end of the Napoleonic Wars and one destination that was particulary alluring was the biblical land of ancient Egypt. This paper examines British travelers to Egypt and how their published works both revealed and constructed a particular view of Egypt during the 19th century. Travel and travel literature accompanied and even facilitated the developing disciplines of archaeology and Egyptology, increasing the knowledge of and interest in the world of the Ancient Near East. This corpus of writing, often with its accompanying illustrations, also served to create a fabricated illusion of the biblical world, fashioned from both ancient and contemporary Egypt.展开更多

The heritage tourism increases the local employment and income, however, brings some problems at the same time, changing the traditional living way and industrial structure. The sustainability of economic development by tourism is also questioned. Fujian Tulou is a world heritage site in China, inscribed in 2008. The nomination has brought great changes to the sites, especially the flourishing tourism industries by the local communities as well as the tourism companies. The latter also take part in the management of the heritage site and get most of the income. The data in economic areas is analyzed in this study and explains the cultural tourism as a positive drive for the local economy, which contributes little to the life of locals. With the analysis of the changes and benefits from the tourism, we have found that tourism, as a dominant industry, might be a potential negative element for heritage conservation. According to the different situations of sites in Fujian Tulou, a proper planning of management is in need to integrate the tourism, conservation and development.展开更多

Fulfilment of this commitment will require integration of the conservation of sites with the sustainable use and management of natural resources in a larger area beyond the boundaries of sites. Identification and demarcation of areas for conserving World Heritage sites and sustainable development of broader regions must derive from an in-depth knowledge of people-environment relationships. The management of Angkor-an iconic World Heritage site -has been primarily focused on conservation and restoration of monuments within the boundaries of the site. However, that focus is now shifting towards addressing environmental, social and economic challenges for sustainable development of the broader landscape described in this paper as the Angkor ecosystem. Angkor has the potential to demonstrate the application of an ecosystem approach to sustainable development--advocated under the UN Convention on Biological Diversity. The site could be a laboratory for new research on cultural ecosystem services as a tool for bridging site conservation to the sustainable development of the Siem Reap province where the site is located.展开更多

They are quite different from other common ecotourism areas, because of its original and unique system, sensitive and vulnerable landscape, and peripheral cultural features. Therefore, the tourism development in the nature heritage sites should be on the premise of ecological security. The evaluation index system of tourism ecological security in nature heritage sites was constructed in this article by AHP and Delphi methods, including nature ecological security, landscape visual security and local culture ecological security, and the security thresholds of indices were also established. In the indices' weights of the evaluation model, the nature ecological security ranked the highest, followed by tourist landscape visual security and culture ecological security, which reflected the influence degree of the limited factor to tourism ecological security. Then, this paper carried out an empirical study of Kanas of Xinjiang Uygur Autonomous Region, China, which has the potential to be the World Nature Heritage. On the basis of the data attained from survey and observation on the spot, as well as questionnaire answered by tourists and local communities, the ecological security status in Kanas was evaluated. The result showed that the status of Kanas tourism ecological security was better, but there had some limiting factors. Lastly, effective measures were put forward to ensure its ecological security.展开更多
