Specifically, the results indicate a sharp in ablation with debris cover thickness increasing from 0-4 cm followed by a decrease in ablation with debris thickness increasing beyond 4 cm for the glaciers No. 72 and No. 74. Spatial distributions of debris layer on the three reference glaciers have the same characteristics, the overall distribution from the vertical, the maximum thickness of debris in the glacier terminal, and the thickness of debris is constantly thinning since the end of the glacier increases with altitude. For the overall distribution from the horizontal, the regular pattern of debris thickness from both sides to the middle is diminishing. The debris on the zone of Tuomuer Peak mostly covered the glacier tongue and is mainly distributed below the altitude of 4 000 m; the area of debris covered approximate accounted for 14.9% on the entire glacier area in this region. Spatial distribution of debris layer on the zone of Tuomuer Peak is mainly affected by the elevation of the glacier terminal, followed by the slopes orientation, the sizes, and so on.展开更多

The deposition processes and the characteristics of mineral dust microparticles from aerosol to fresh snow, and then evolution to the snow pit were determined. Total dust microparticle concentration in the surface snow and aerosol showed a similar temporal variation trend, which was strongly associated with regional and local at- mospheric circulation in the Tianshan Mountains region of Central Asia. Especially from November to February, the correlation coefficient of microparticles concentration in surface snow and aerosol is very high （R2=0.7）. Vertical profiles of microparticles in the snow pits showed that observed dust layers were in high correlation with concentration peaks of large microparticles （d〉10 μm）, but low correlation with that of fine microparticles （d〈1μm）. Moreover, explicit post-depositional process of dust particles was studied by tracking some typical dust concentration peaks in the snow pit. We find that late sum- mer is a key period for post-deposition of dust particles in the snow, as particle concentration peaks in the snow pit evolve intensely during this period. Such evolutional pattern of large particles makes it possible to preserve information of atmospheric dust in the snow, which offers an available proof to reconstruct historical climate using ice cores on Glacier No. 1 and other gla- ciers in the Tianshan Mountains.展开更多

The purpose of this study is to explore the ways adopted by tribal residents to maintain their own culture and tribal life in the process of disaster, post disaster reconstruction and post disaster adjustment. Veoveoana Village in Taiwan is an indigenous tribe that relocated after a disaster and was reconstructed and developed through tourism development. This study performed the research by participant observation and in-depth interviews on Veoveoana Village. The analytical results showed that: 1) development of the tourism industry can result in cultural reconstruction of the post-disaster tribe and maintain the people’s incomes;2) although the government constantly assists with the rehabilitation of tribal industry by various policies, the implementation cannot effectively continue and the outcome is insignificant;3) due to the gap between permanent prefabricated housing and original tribal cultural features, the residential rate is not high. According to the research findings, it is suggested that, in the process of post-disaster reconstruction, the government and private non-profit organizations should respect the intention of the majority of the indigenous people. In addition, it should cultivate professional manpower for the subsidized projects.展开更多
