A study on climatic division of animal husbandry in Inner Mongolia

Abstract: According to the records from 107 meteorological stations in Inner Mongolia and using the gradient inverse square formula, the climatic grid data of 1 km 1 km were calculated by interpolating under the GIS environment. Based on the distribution characteristics of animal production structure in Inner Mongolia； the climatic regionalization indicators of five major grazing livestock, including horses, cattle, sheep, goat and camel, were identified.Using these climatic regionalization indicators the grades of the five major grazing livestock of each grid were classified and the regionalization thematic maps of the five major grazing livestock were also achieved. Each kind of region was remarked and suggestions for sustainable development of animal production were proposed. This study could provide scientific basis to the adjustment of agricultural structure and the optimal distribution of animal husbandry on grasslands in Inner Mongolia.
