Study on the Agriculture Resources and Increase of Grain Yield of Inner Mongolia Autonomous Region

This paper focused on the in-depth analysis on the relationship between the increase of grain yield and arable land resources in Inner Mongolia Autonomous Region from angles of the changing trend of arable land,arable land and grain production,changing trend of the national proportion of food crop acreage and grain yield accounted for the national proportion,the changing trend of the per unit area yield of grain,etc.Then,the paper discussed arable land resources binding factor in sustained increase of grain production and proposed measures and recommendations to improve farmland productivity.
