| Based on 50 years historical materials, typical investigation and field experiments on agriculture, animal husbandry and industrialization of agricultural and animal products, applying ecological, economic and systematic analysis methods, farming system in Inner Mongolia are analyzed, such as the increasing of agricultural production and its contribution factors, and the change characteristics agriculture and its motive factors, and the developing situation and drawback factors of agricultural industrialization. According to above data and analysis methods, the developing laws and mechanism on farming system and optimize countermeasures and technical supporting approaches to agricultural structure are deeply discussed.1. New structure of agriculture-based and conbination of agriculture and animal husbandry has come into being in Inner Mongolia. Fanning system now tends to market-oriented, advanced techniques, intensive input and sustsinable objectives. With the increasing of grain yield, food supply has increased, and the same time, agricultural values, per capita food possession and income of fanners increased signifisantly. Sowing areas of Inner Mongolia changed from low-yield crops to maize, wheat, soybean and potato, in 2001, total sown areas was 5031 thousand hm2, grain production was 14.285 million tons. Animal husbandry in Inner Mongolia had developed steadily, total animals were 73872 thousands and meat production is 1370 thousands tons. And animal production values is RMB 479.5 billion, some big companies such as Yili Co.,Ltd, Mengniu Co.,Ltd and Erdos Co.,Ltd, which are as the processing chains of agricultural and animal products, are playing important roles in whole areas.2. According to compartmentalize principles and methods to farming system, Inner Mongolia Autonomous Region is divided into five fanning system types: Northeastern semi-humid and semi-arid low-hill soybean, wheat and rape planting and cow feeding and processing areas, simply called Northeast Farming Areas; II. Eastern semi-arid plain well-irrigated maize, rice planting and cattle and sheep feeding and processing areas, simply called Eastern Farming Areas; HI. Middle and eastern semi-arid prairie feed planting and sheep feeding and processing areas, simply called Middle and Eastern Fanning Areas; IV. Middle arid and semi-arid river-irrigated wheat, maize and sunflower planting, and cow, sheep and goats feeding and meat and hair processing areas, simply called Middle Farming Areas; V. Western arid oasis camel feeding and camel hair processing areas are simply called Western Farming Areas.3. Production of agricultural and animal products has showed localize significantly. Middle Farming Areas and Eastern Faming Areas are main grain production areas or 87% of total grain production. Maize is mainly in Eastern Farming Areas or 66.98% of total maize production; Wheat is in Middle Farming Areas and Northeastern Farming Areas or 46.98% and 27.07% of total wheat production, respectively; Potato is mainly in Middle Farming Areas or 81.83% of total potato production; Soybean is in Northeastern Farming Areas and Eastern Farming Areas or 62.76% and 34.22% of total soybean production, respectively. As same as grain production, Eastern Farming Areas and Middle Faming Areas are main meat production areas or 44.10% and 34.61% of total meatproduction; Middle Faming Areas and Eastern Farming Areas are main milk production areas or 39.31% and 28.65% of total milk production.4. It showed that through analyzing the motive factors to farming system evolvement in past 50 years in Inner Mongolia: Total agricultural machines, rural electric power, chemical fertilizer use, effective irrigation areas and species and cultivation techniques are factors to grain production, and these factors played different roles in different periods. Among above factors, Total agricultural machines and effective irrigation areas are the most important factors to total agricultural production values, and chemical fertilizer use, species and cultivation tech...
