The research performed analysis on local tourist re- sources and existing problems based on researches available in order to rational exploitation on resources and advance tourism development. Finally, countermeasures were proposed including education promotion, improvement on quality and awareness, in- creasing talent pool, rebuilding image, scientific planning, and further exploitation on tourist products.展开更多

According to emission factors of local air pollutants and GHG of coal-fired power industry in different hydropower service regions, we estimate the effect and synergy of local air pollutants and GHG reduction achieved by hydropower development in Tibet, examine the main factors constraining the effect and synergy, using correlation analysis and multiple regression analysis. The results show that: 1) During the period from 2006 to 2012, the effect of local air pollutants and GHG reduction achieved by hydropower development in Tibet decreased as a whole, while the synergy increased first and decreased afterwards. 2) The effect and synergy of local air pollutants and GHG reduction achieved by hydropower development in Tibet vary significantly across different hydropower service regions. The effect based on emission levels of Central China power grid(CCPG) and Northwest China power grid(NCPG) was more significant than that based on emission level of national power grid(NPG) from 2006 to 2012, and the synergy based on emission levels of CCPG and NCPG was also more significant than that based on emission level of NPG from 2010 to 2012. 3) The main factors constraining the effect and synergy based on emission levels of NCPG and CCPG included SO2 removal rate and NOx removal rate, the effect and synergy based on emission level of NPG was mainly influenced by net coal consumption rate. 4) Transferring hydropower from Tibet to NCPG and CCPG, and substituting local coal-fired power with hydropower can greatly help to co-control local air pollutants and GHG, transform the emission reduction pattern of the power industry and optimize energy structure.展开更多

Attitudes and perceptions towards Tibetan community participation in ecotourism were analyzed using face to face interviews. Most residents supported the development of ecotourism. They are willing to engage in ecotourism projects and accept ecotourism education and training, and expect that the government provides opportunities for them to participate in making ecotourism decisions. Most residents believed that ecotourism promotes local economies and social development, and enhances the ability and quality of local residents while improving their environmental consciousness. However, some residents were concerned that ecotourism may destroy local natural environments and Tibetan folk customs and culture. The level of community participation in ecotourism development is only in its infancy in Shenzha, but there is strong potential. The chief participatory approaches of ecotourism development for most residents were providing labor and catering services and commodities for tourism, and Tibetan performance singing and dancing. Limiting factors include language, a shortage of knowledge and skills, and poor ecotourism infrastructure. Most residents had little confidence that the government was willing to support them to participate in ecotourism. We put forward some mechanisms to enhance the level of community participation in ecotourism in this important region.展开更多
