According to Garci’a (2002), on the theoretical plan, the regionalizao is based on the recognition of that the different distribution of the urban population in the space happens of the social and economic efficiency, whose more concrete substrata are the external economies of scale proceeding from the urban concentration and of it offers of specialized jobs that, in turn, backward-feeds the social reception system, modifying its structure, throughout the time. The formation of areas that if they structuralize in primary sector comes ahead losing space the coming of great international corporations. The relations partners in some focos in the Amaznia have suffered the interference from other cultures and with this, associations have itself directed to give to attention to this excellent aspect before the society 3.Regionalizao According to a Partner-economic Perspective. The Brazilian socioeconmica dynamics comes causing deep ambient changes in the Amaznia through the fast deforestation of this vast bioma, with the consequence loses of its ecological services (FEARNSIDE, 1997). The index of Partner-economic Development (IDSE) is calculated on the basis of the exploration of some sources of available data, which bring a considerable gamma of disintegrable social and economic information until municipal level e, in certain cases, intramunicipal, namely: demographic census of 1991 and 2000 and farming one of 1995/1996 (IBGE, 1996; 1996; 2000).

Beyond estimates of gross domestic product of cities (ANDRADE & MOUNTAIN RANGE, 1999), given of exploration and lumber production (VERSSIMO et al., 2001), municipal bank of information (IBGE, 1998) and profile of the Brazilian cities (IBGE, 1999). The antrpica Presence has been each sees present in the Amazon region, for this is analyzed diverse factors that measure of systematic form this process; According to Monteiro and Sawyer (2001) amongst the pointers of pressure of ambient impact, the index of antrpica pressure, represents a pointer of economic and demographic pressures on the environment. According to these authors, the index of antrpica pressure, constructed on a secondary database, synthecizes the pressures of transformation that one determined half-environment is subject due to action human being, wants either in regards to the pollution or depletion of the natural resources. .
