		<abstract>This study aimed to use multitemporal images obtained by the sensed TM/Landsat in the period 1997 to 2009, aimed at monitoring and quantification of the dynamics of use and occupation of land in the sub-basin of the river Jauru, State of Mato Grosso. The sub-basin is located in the coordinates latitude 14º20'39"S and 16º36'23"S and longitude 57º37'13"W and 59º35'49"W. The approach used consisted of comparative analysis of the human action of man in the sub-basin and the area that comprises the so-called "wetland. We used images obtained by the sensor TM/Landsat-5 for the years 1997 and 2009, the images were geometrically corrected with the aid of the letters of DSG / IBGE 1:100.000 scale were subsequently processed using routines implemented in SPRING software v. 5.1. The results were endorsed by using the kappa coefficient, was considered very good (K= 0.79 or 79%) for unsupervised classification using the classifier Isoseg to 95%. In the mapping to the classes referred to as anthropogenic and vegetation, the results were excellent, respectively, K = 0.92 or 92% and K = 0.98 or 98%. The values were tabulated and compared with the percentage of deforestation occurred during the study period, noting that across the sub-basin were disturbed an area of 1105.3492 km2 equivalent to 9.13% of the entire sub-basin. The values of the disturbed areas were considered high taking into consideration the short space of time, and by the various conservation programs available.</abstract>
