This work has as a main objective to analyze and spot the evolution of complexity conversion of different types of landscapes in Benfica settlement project, southeastern region of Para. We used images from Landsat-TM corresponding to 1987, 1992, 1996, 2001 and 2005 and geoprocessing techniques conducted by SPRING system, as well as field data and graphical models of landscapes. Applied methodology allowed the identification, classification and quantification of six types of landscapes: forest (TPO, agricultural mosaic (TP1), mosaic of agricultural pasture (TP2), large areas of pasture (TP3), large areas of pasture and babasu (TP4), and forest babasu palm (TP5). Integration of results led to a range of complexity of the types of landscapes, where the degrees of intensity ranging from "simply" (0) to more "complex" (12), being the more intense the types of forest landscapes (TP0), agricultural mosaic (TP1) and mosaic agricultural pasture (TP2). The geographical approach reflected different dynamics that are established based on the conditions and chances of maintaining or not the production systems, thus increasing or decreasing its complexity. The focus on the complexity of a typology of landscapes allowed addressing issues related to their function and proved to be applicable to any plan or strategy for environmental conservation.
