Molecular Biomarker Characteristics of the Linxi Formation Source Rocks in the Middle-Western Region of Inner Mongolia:New evidence for late-stage tectonic evolution of the Paleo-Asian Ocean

Objective Two important geological issues have long been controversial in the Xing-Meng area of North China. 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.

Does empowering women benefit poverty reduction?Evidence from a multi-component program in the Inner Mongolia Autonomous Region of China

Ending poverty is a top priority of the international development agenda,and governments worldwide have attached great importance to poverty alleviation measures.However,poverty reduction policies have mostly focused on men,which has widened the gap in productivity and income between men and women and increased gender inequality.This paper aims to determine the impacts of a multi-component program on women's empowerment and poverty reduction,and explore the role empowered women play in poverty reduction.The dataset used in this study was collected in nine poor counties of Ulanqab City in the Inner Mongolia Autonomous Region of China at the end of 2014,yielding a sample of 900 households.Recall questions were used to reconstruct the baseline data and build a panel dataset.Smaller groups of rural households were further identified to better target the women in the beneficiary group.To control the selection bias,propensity score matching,inverse probability weighting,and the difference-in-differences matching method were used to analyze the effect of the program and undertake robust checks.The results show that the program has positive effects on women's empowerment and poverty reduction simultaneously.Empowering women also has positive effects on poverty reduction,and the women who were the beneficiaries have contributed to increasing the incomes and living standards of households.Training,microfinance,and associations are common means or strategies to empower women to address poverty.This paper provides new empirical evidence that women can benefit from a gender-focus program through portfolio intervention such as training,cooperatives,and credit.Empowered women further improve the livelihoods of poor households and help lift them out of poverty.The results suggest that researchers and policymakers need to pay more attention to poverty issues from the perspective of gender.

First record of Early Cretaceous pterosaur from the Ordos Region, Inner Mongolia,China

Income and Expenditure of the Herdsman in Inner Mongolia Autonomous Region: A Case Study of Xianghuang Banner in Xilin Gol League

Based on the household survey data concerning herdsmen's families in Xianghuang Banner, Xilin Gol League, Inner Mongolia, we analyze the income and consumption structure of herdsmen's families in the western regions during the period 2008-2009. 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.

Opportunities of Inner Mongolia's economic development under the background of the “Silk Road Economic Belt”

"The Silk Road Economic Belt" is a great strategic thought, through which China deepens allround reform and opening up, especially in the major move of opening up to the west. Inner Mongolia autonomous region owns the superior geographical position and was closely related to the Silk Road in ancient times. In the new stage, Inner Mongolia autonomous region should seize the opportunity of the development strategy, and strive to develop economic construction under the background of the belt of Prairie Silk Road, and play an important role in the economic belt of the "Prairie Silk Road".

The Crustal Velocity Structure of Western Inner Mongolia

The terrain of Inner Mongolia is long and narrow, and the geological structure is complicated. The South China crustal velocity model and Inner Mongolias 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.

Sensitivity of livelihood strategy to livestock production and marketization:An empirical analysis of grasslands in Inner Mongolia,China

Recent researches have primarily focused on the relationship between livelihood strategies and livelihood capital,with few empirical studies on the sensitivity of livelihood strategies to livestock production and marketization in Inner Mongolia Autonomous Region of China.This study used an income distribution approach to categorize livelihood strategies of the respondents(n=394)into three types,i.e.,herder livelihood strategy(LS1),petty-herder livelihood strategy(LS2),and non-herder livelihood strategy(LS3).Using the multinomial logistic regression model,we compared livestock production and marketization across the three livelihood strategies.Our findings showed that(1)livestock production and marketization tended to favor LS1;(2)an increase in the land asset(contracted and rented grassland)and off-take rate increased the probability of households choosing LS1;(3)stocking rate was higher for LS1;and(4)the higher critical market-related risks perceived by herders were animal price and hay and corn price.Moreover,higher livestock price acted as a deterrent to diversifying into other livelihood strategies(LS2 and LS3).Finally,this study advocates for policies that will promote the land transfer market,adopt modern techniques in animal husbandry,improve the medium for disseminating market information to herders,and provide incentives for long-term livelihood transformation.

The Focal Depth Analysis of the Inner Mongolia-Ningxia Border Area Earthquakes

We selected the 103 M_L≥2. 5 earthquake waveform data from the Inner Mongolia-Ningxia border during 2009-2015,which was recorded by the Inner Mongolia Digital Seismic Networks and used the simplex method, Hyposat method, double difference location method,and deterministic method (PTD) for the determination of focal depth,and compared the results. 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.
