The transitional areas of farming and pasturing in the northeastern China are part of the typical vulnerable region. Owing to this, the land use change would have a great effect on the living standard of the local people and the coordination of environment and economics. In this paper, on the basis of the quantitative analysis of the land use change, the land use changes of the quantitative structure change, the using level, and the regional diversity in transitional areas of farming and pasturing in the northeastern China during the recent 10 years have been analysis.In the research region the cultivated areas have been increased with the variation of the national policies and the population. Meanwhile there has been a decrease in grass land areas owing to the vulnerable environment and the human activities. From the research, we can see that the changes of land use level and the quantitative structure mainly reflected by the cultivated land and the grass land. In addition, the regional difference of the land use is clear in the research areas. Thus we can provide scientific basis for the sustainable use of the land resources.
