Inner Mongolia farming-pastoral zone is the transition zone mainly grazing industry in the the Yi Mu context, mainly from farming and raise livestock husbandry. The heart of the natural environment and the socio-economic conditions have shown a significant transition characteristics. Inner Mongolia farming-pastoral zone in general between the two precipitation lines of the annual precipitation of 300mm ~ 500mm across Inner Mongolia 8 cities and 47 counties in the scope of its boundaries, a total area of ??approximately 426,700 km2 [1]. Higher annual accumulated within the region, adequate lighting, natural conditions more suited to the growth of crops, but the area is semi-arid areas, the precipitation is a serious shortage of traditional agriculture is mainly rainfed, leading to low grain yield of arable land, has seriously hampered the local community economic development comprehensive improvement of arable land in the region and its great potential, the need for strong, significant benefits. In view of the above reasons, the paper from the Inner Mongolia Autonomous Region since 2000, the country approved the implementation of the land consolidation project selected 32 Inner farming-pastoral area of ??land consolidation project as a research object, based on the knowledge of related disciplines such as soil science, crop cultivation and practical experience in the implementation of land consolidation project, and consulted experts, academics identified 16 observational factor, as Inner Mongolia and pastoral ecotone indicators are based on the study of the quality of cultivated land. Inner Mongolia farming-pastoral area of ??cultivated land quality and impact factor research: farming-pastoral area of ??arable land in Inner Mongolia before and after a comprehensive renovation, the quality of cultivated land, grain production capacity (in this paper, with grain production capacity to reflect the changes in the quality of arable land) and its impact factor changes; Inner Mongolia farming-pastoral area of ??arable land to establish a correlation between the quality of cultivated land with impact factor model food before and after the implementation of the land consolidation project incremental irrigation guaranteed rate, terrain slope, effective soil thickness The degree of salinization, drainage conditions, surface texture, profile configuration from the barrier layer depth, irrigation water, soil erosion, land use coefficient farmland main limiting factor changes multiple regression analysis. In summary, the study shows that the analysis of the cultivated land in Inner Mongolia, and pastoral ecotone: in Inner Mongolia Farming ecotone improve arable land with irrigation rate, soil thickness increase, the improvement of the terrain slope, grain production capacity has increased; the higher the degree of salinization, lower grain production capacity, the better the drainage conditions, the higher the grain production capacity. Analysis confirmed that land consolidation is to improve the quality of cultivated land is the most effective, the most direct method of land consolidation can effectively improve the influencing factors of the arable land and the limiting factor, land consolidation, water-saving 10 to 50% of the grain production capacity by 10 to 60% [2]. Therefore, the Land Consolidation building is important for advancing the engineering of Inner Mongolia \
