The thesis made a study on the construction of the road transportation in Inner Mongolia. Through analyzing the social economys development, the present of synthesis transportation and the infrastructure, the equipment of goods traffic and the present situation of the operation and the management, the problems between road transportation and social economic development in the structure in Inner Mongolia were pointed out. Then the methods of regression forecast, flexible coefficient, and straight line tendency forecast etc were used to estimate the quantities of the goods and Freight Ton-kilometers. According to the future demands of goods volume of road transported and the development of freight transportation turnover quantity in Inner Mongolia and the existence question, the adjustment plan of the road goods traffic station yard layout, network structure transports strength structure and service system have been proposed, and then the synthesis appraisal of the plan has been carried on, the Inner Mongolia road goods traffic structure adjustment safeguard measure was proposed.

The second chapter describes the formation of the pool of state controlled lands and the establishment of land market. The third chapter analyzes the government policies regarding land sale from the Independence to 1850s and the federal government"s diversified land distribution polices in the latter half of the 19th century. In the Forth chapter, the author assesses how American government" s land policies assisted the development of agriculture, communications and transportation, western urbanization and the formation of a national market. Chapter Fivediscusses the controversial issues of the land speculation and The Homestead Law, which affected the governments land policies.
