Five years after the implementation of the tourism precision poverty alleviation strategy, how effective it has been in alleviating poverty remains to be tested. This study, through a study of 241 farm households in 10 national tourism poverty alleviation key villages in the Qinba Mountain region of Hanzhong, southern Shaanxi, finds that rural tourism has contributed to a general increase in farm household income, but the effect of income increase varies significantly between households that have escaped poverty and non-poor households, and there is no significant difference in income between those who participate in tourism and those who do not. The study concludes that the poverty-reducing effects of tourism are conditional, with the poor quality of human capital being the main obstacle to farm households’ income growth, the institutional mechanism for tourism participation is inadequate, effective farm household tourism participation is significantly low, and non-farm work constitutes a substitute for farm households’ tourism livelihood options. The primary stage tourism scenic spots have a limited role in driving the income of farming households, and the geographical location limits the effective participation of farming households. Accordingly, the following countermeasures are proposed: (1) in terms of strategic decision-making options, establish a screening mechanism for tourism participation in poverty alleviation and implement diversified poverty governance; (2) in terms of tourism development strategies, encourage the integration of multiple industries and synergistic development, realize the two-way interaction of “+ tourism” and “tourism +”; (3) in terms of development methods, adhere to the participatory development path, improve the institutional mechanism for tourism participation, stimulate the endogenous motivation of farmers, and explore the dynamic participation path of “bottom-up”. (4) In the development of endogenous power, strengthen skills training, improve the comprehensive quality of farmers and their participation level and ability; (5) In the coordination and protection, play the coordinating and leading role of grass-roots party building, and continuously cultivate and strengthen tourism cooperative organizations.

The anthropogenic heat release from tourism activities has a cumulative effect on glacial retreat when coupled with climate change. Mitigating the impacts of glacial tourism activities on glaciers and promoting the sustainable development of glacial tourism have become urgent issues. Taking Yulong and Hailuogou glacier tourism destinations as examples, we collected survey questionnaires related to glacial tourists (n=1113) and tourism companies (n=329) by systematic field surveys during 2016–2017, and we obtained data on energy consumption from catering, accommodation, transportation, sightseeing, shopping, entertainment, and waste disposal. This study builds a responsible tourism system and discusses the strategies and measures used to engage stakeholders (mainly tourism companies, tourists, local governments, tourism associations, and the central government) in responsible tourism in order to reduce the impacts of tourism activities on glaciers. These strategies mainly include: improving the energy efficiency of the supply of tourism products and services, promoting the consumption of low-energy tourism products and services, strengthening the supervision and management of low-energy consumption tourism development, creating an environment for energy savings and consumption reduction, and establishing a long-term operational mechanism for responsible tourism management. A rewsponsible tourism system allows stakeholders to properly address this dilemma, internalize sustainable development goals to find their intrinsic self-discipline, and work together to fulfill the public responsibility of realizing the sustainable development of glacial tourism.

A newly designed autonomous instrument was evaluated for long-term ocean turbulence measurements in the South China Sea from October 19, 2013, to February 10, 2014 at 21°09.90′N, 117°42.03′E. A shear velocity time series was collected continuously for 115 days at a single depth of 250 m using two orthogonal shear probes (PNS06). The mechanical design of wings is developed for an observation platform to achieve characteristics of stability and flexibility of current direction tracking. The depth and pitch in comparison with ambient current speed are analyzed, and the results indicate that the platform has satisfied stability requirements for turbulence measurement. The comparison between the instrument heading and current direction shows that the instrument flexibly responds to variations of ambient currents. Throughout the observation period, 62% of the data sets is of significant correlation with correlation coefficients above 0.5, and 4% is of strong correlation. The shear velocity spectra correspond well to the theoretical Nasmyth spectrum, and the magnitude of dissipation rates estimated from shear is approximately Ο(10⁻⁸) W kg⁻¹. The moored instrument is functional as designed and provides a reliable observation platform for extended turbulent measurements.
