The regionalization of eco-productive paradigm is to delineate and reveal precisely the spatial differentiations within a region based on the thorough analyses of the natural ecological condition

the social-economic-technological development level

and the comparative advantages for farming

livestock husbandry and forestry production.The regionalization of eco-productive paradigm is also to design a blueprint for guiding the development of integrated agricultural production according to the regional differentiations and giving priority to the ecological conservation at the same time.The blueprint drawn by the regionalization should be related to specific spatial areas of the region.Based on synthetically analysis of the characteristics of ecological environments of the farming-pastoral zone in North China

the principles of eco-productive paradigm regionalization are discussed

and indices and nomenclature of eco-productive paradigm regionalization are proposed.The results show that there are 3 domains

7 regions and 21 districts.
