The results show that the herdsman's source of income is single, mainly focusing on livestock sale, with poor ability to resist risks; the share of purchase expenses of forage in the consumer spending is the greatest, growing rapidly, followed by spending on food, education and health care; there are many policy subsidies for housing. The characteristics of herdsman's income and consumption are jointly determined by natural factors, market factors, policy factors and personal factors. Based on this, corresponding recommendations are put forth in order to increase herdsman's income and improve the consumption structure: the herdsman should strengthen breeding techniques to improve scientific breeding and increase income, change consumer attitudes, save moderately, and strengthen ability to resist risks; the government should increase the policy subsidies for pastoral areas, strengthen education, training, health care for herdsman, and promote herdsman's quality.展开更多

Grassland is not only a kind of important resource but also a great attraction to visitors. Therefore, the integrated development and sustainable utilization of grassland tourism resources are of great significance. This paper, based on the analysis of literatures and the current problems existing in grassland tourism, summarizes the speciality of grassland tourism development, deals with the problem of speciality, and raises the modes of regional development, product development and management. This paper takes Inner Mongolia, the famous grassland tourism destination as example and carries out empirical research. Based on the status quo of grassland tourism resources in Inner Mongolia, this study analyzes the character- istics of grassland tourism resources, the necessity and feasibility of integrated development, then proposes the following suggestions: idea for development, mode of development, regional cooperation, tourism products development, espe- cially the three modes of development based on the resources conditions - the mode of relying on market, the mode of combination aggregation and the mode of relying on quality.展开更多

In this paper, with the network travel notes of self-driving tourists as the research object, methods such as text analysis and visualization were adopted to study behavior patterns of self-driving tourists, tourism experience,time-space migration, and distribution of tourism resources in Inner Mongolia, from the multiple dimensions of mobile drivers,perceived dimensions, and spatial migration. The results showed that: ① self-driving tourists had a variety of motivations for traveling, in which love for nature dominated; ② self-driving tour destinations were mainly Hulunbuir,Ordos,and Alxa League;③ spatial migration was characterized by obvious seasonal fluctuations. The research on the behavior of self-driving tourists in Inner Mongolia is an important part for the study of the connection between tourism resources and market connection in Inner Mongolia, and is of significance for guiding the theory, practice and policy formulation of self-driving tours in Inner Mongolia.展开更多

The first concerns the final closure of Paleo-Asian Ocean in Xing-Meng area, and the other concerns the folding and lifting of the Xing-Meng Trough. The focus of thses issues is the Late Permian sedimentary environment, which is generally considered to be either an exclusively continental environment or from the closed inland sea environment in the Early to Middle stage to continental lacustrine environment in the late stage. In recent years, we have successively discovered abundant typical marine fossils (e.g., bryozoans and calcareous algae) in the Upper Permian thick limestone layer from Linxi County and Ar Horqin Banner in eastern region of Inner Mongolia and Jiutain County in Jilin Province. These significant findings have attracted the attention from fellow academics.展开更多

[Methed] On the basis of the improved ecological stress index (ESI) analysis method, the eco-environmental stress trend of Inner Mongolia from 1996 to 2009 was analyzed, as well as the changes of eco-environmental stress in major industrial cities of Inner Mongolia in 2008. [ Result] With the economic development of Inner Mongolia from 1996 to 2009, the U-shape change could be found in the eco-environmental stress, showing an upward trend on the whole, especially since 2003, and there was a sharp raise in the environmental pollution index. In addition, the eco-enviren- mental stress lessened in most major cities of Inner Mongolian in 2008, but it was in a polarization state, that is, Baotou, Wuhai and Hohhot biased resource and energy consumption, while Ordos and Chifeng biased environmental pollution. [ Conclusion] The research could provide scientific ref- erences for the protection of ecological environment and the adjustment of industrial structure in Inner Mongolia.展开更多

The South China crustal velocity model and Inner Mongolias optimal crustal velocity model 2015 cannot fully meet the earthquake location requirements of Inner Mongolia. Based on the seismological observations produced by Inner Mongolia Seismic Digital Network from 2009 to 2016,the initial model was obtained by using the linear fit of the seismic phases and the converted travel time curve. The Hyposat results of 225 earthquakes that occurred in western Inner Mongolia were scanned using this model,and the velocity model for western Inner Mongolia was determined as follows: V1= 6. 06 km/s;VPb= 6. 61 km/s; Vn= 8. 12 km/s; H1= 30 m; and the Moho depth H = 44 km. Comparison of the test results of the new model and the reference model shows that the residual error of the new model and the mean deviation of the epicenter location have obviously decreased.展开更多

The CAP moment tensor inversion method is used to determine the focal depths of the Alxa Left Banner M5. 8 and M4. 2 earthquakes. The final results of the focal depth by the deterministic method (PTD) and the double difference location method fit well with the tectonic characteristics of the Inner Mongolia-Ningxia border area,but those of the simplex method and the Hyposat method do not. The average depth of the Inner Mongolia-Ningxia border seismic tectonic zone is 13. 32 ± 8 km.展开更多
