Xapuri County, founded on March 22nd 1904, its situated on a 5.346 km2 area, is located on a higher region of Acre, and it is considered the birthplace for The Amazon s environmental fight, due to the conflicts and land exploitation, in order to control the land, led by the union leader Francisco Alves Mendes Filho, internationally known as Chico Mendes. Currently, Xapuri County has been dealing with a difficult challenge in searching for alternatives for its soil s use that would enable the deforested areas to have a sustainable development, as well as to better exploit the Forest s area, for the environmental capability and susceptibility and to fully incorporate the locals knowledge. Therefore, it is necessary to have socio-environmental knowledge, in order to distinguish the current employ of the County s land, as well as to better understand its natural resources on the same level as the existing cartographic equipment, teamwork that would allow preserving the environment and executing such contemporary development to exert and work the county s land. The aimed is to present alternative settings of reasonable and sustainable application of the land, with premises on current land application, along with knowledge of natural resources, specially soil and hydrographic characteristics, in order to distinguish Soil-forming environment factors, to form a foundation for the County s projection. Thus, a soil recognition research was conducted, and from such inquiries, a geological and ridge map was formulated, as well as the land s exertion by SRTM and LANDSAT satellite images, minding the preservation of Soil-forming environment factors. Consequently, to correlate Soil-forming environment factors with classes of land exertion and obtain appropriate zoning of land exertion and zoning of the Hydrographic factors on soil, on a 1:100.00 scale. Thus, the County can be divided into four Soil-forming environment. It was noticed a predominance of Clay soils, with strong influence from the source materials and clay migration, as well as not so weathered Oxisols soils. The land application s adequacy showed class predominance: lack of substantial impact (39%), as consequence of the largest preserved forest area (77%). However, results showed low to high impact on the application concentration outside of the preserved area. According with the zoning of the Hydrographic factors on soil, it was possible to observe Xapuri County in a territorial management perspective as a whole, as a result, with grounds on these studies, concluding considerable change in Areas of permanent preservation.
