M_s 6.2 and M_s 6.1 earthquakes occurred in Dayao County in Yunnan Province in July 21 and Oct.16,2003.The paper takes the Dayao County as an example to study the earthquake disaster impact on the rural residents,and to find out the risk awareness and the response of rural residents to the earthquakes.The analysis of investigation showed that the rural residents is the most casualties in the earthquake disaster and the most painful victim.They can get some experiences and lessons from the earthquake disaster and enhance their risk awareness,but because of the backward economy,the rural residents cannot basically change the vulnerability of the hazard affected-bodies.The improving capability of disaster prevention and reduction in China rural areas need the active participation of the government.
This study focuses on analysis methods for monitoring coal fires, using a combination of multi‐temporal thermal infrared data, high spatial resolution remote sensing data and field measurements. This technical note is prepared as a feasibility study for the detection of coal fire dynamics in the Inner Mongolia Autonomous Region in northern China.
Due to their complexity, hazard interactions are often neglected in current studies of multi-hazard risk assessment. As a result, the assessment results are qualitative or semi-quantitative and are difficult to use in regional risk management. In this paper, the crop loss risk due to heavy rain and strong wind in the Yangtze River Delta (YRD) region of China was quantitatively assessed, based on the joint return periods of these hazards and a vulnerability surface. The joint return period is obtained with a copula function based on the marginal distribution of each hazard. The vulnerability is fitted by considering the joint hazard intensity, the sown area of crops, elevation, and GDP per capita. The results show that counties with a high value of joint hazard probability are clustered in the southeast coastal area and that the value gradually decreases from south to north and from east to west. The multi-hazard risk has a similar pattern, with a large value in the southeast coastal area and a low value in the northwest. The proposed method can be used for quantitative assessment of multi-hazard risk, and the results can be used for regional disaster risk management and planning.
This paper classifies and researches the documents about tourism organizations in the authoritative tourism academic journal——Annals of Tourism Research,Tourism Management,the only two tourism periodicals access to Social Science Citation Index(SSCI).This paper also analyzes tourism organizations from Tourism Tribune,Tourism science and Tourism forum,as the representative tourism academic periodicals published in homeland.This article makes important research on travel agencies,hotels,scenic spots management organizations,tourist traffic,tourist governmental department as the main themes of tourism research organizations.Finally,this paper points out the future direction and the focus of the study.
For the ecologically vulnerable Qinghai-Tibet Plateau (QTP), hypoxia is increasingly becoming an extremely important environmental risk factor that significantly affects the health of both humans and livestock in the plateau region, as well as hindering high-quality development. To focus on the problem of hypoxia, it is especially urgent to study the surface oxygen concentration (i.e., oxygen concentration). However, the existing research is not sufficient, and there is a lack of oxygen concentration data collected on the QTP. In this study, through the Second Tibetan Plateau Scientific Expedition and Research and field measurements, the oxygen concentration data and corresponding geographic environmental data were collected at 807 measurement points on the QTP from 2017 to 2022, and the spatiotemporal oxygen concentration patterns were estimated. This work filled the gaps in the measurement and research of oxygen concentrations on the QTP while providing data support for analyses of the influencing factors and spatiotemporal characteristics of oxygen concentrations, which is of great significance for promoting the construction of ecological civilization in the QTP region.
