Abstract: According to the records from 107 meteorological stations in Inner Mongolia, using the Gradient Inverse Square Formula, the grid data in Inner Mongolia were calculated by interpolating under the GIS environment,and the resolution of grid data was 1 km×1 km in combination with the distribution characteristics of the grassland types and animal production structure in Inner Mongolia. The climatic regionalization indicators in Inner Mongolia are defined, which include five grassland types, six grassland yields grades and geographical distribution of five major grazing livestock. Using these climatic regionalization indicators, the climate data grades of each grid are classified, the regionalization thematic maps of grassland types, grassland yields grades and major grazing livestock in Inner Mongolia were drawn. Each kind of the regions was remarked, and suggestions for sustainable development were proposed. This study could provide scientific basis for the adjustment of agricultural structure and the optimal distribution of animal husbandry in Inner Mongolia grassland.

Key words: Inner Mongolia, natural grassland, animal husbandry, climatic division
