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

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

In this paper, witii the network travel notes of self-driving tourists as the tesearch 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, fi：om the multiple dimensions of mobile drivers, perceived, dimensions, and spatial migration. The results showed tiiat ①self-cidviiig tourists had a variety of motivations for traveling, in which love for nature dominated; ②self-driving tour destinations were mainly Hulunbuir, Ordos, and Alxa League; ③spatial migration was characterized by obvious seasonal fluctuations. The fesearch on the behavior of self-driving tourists in Inner Mongolia is an important part of the study of the connection between tourism resources and market connection in Inner Mongolia, and is of significance for guiding the theory, practice and poliqr foimuktion of self-doving tours in Inner Mongolia.展开更多
