		<abstract>The soybean is one of the most important crop cultivated in the world. In the 60´s it became the great importance for the Brazilian economy, and the production increased from 3.6% in the 70´s to  18.7% in the 80´s.  The  Mato Grosso ´s cerrado became the principal region of production of this crop in Brazil due to the governamental financial support and research projects, and also due to the characteristics of the soil and relif of the region. The objective of this work was to analyze the advance and the increase of cultivate area of soybean in the biomes of cerrado and forest in three cities in the Mato Grosso State, using remote sensing and GIS techniques for mapping the land use and land cover from 1986 to 2001. The material used was Landsat images aquired in the 1986/87 and 2000/01 years, and the image processing software called SPRING. The techniques used in the image processing metodology were mixture model, segmentation and non supervised classification. The results obtained shows that the soybean is an important pression factor of land use changes in the cerrado´s region, and is not so important in the forest areas.</abstract>
