SUMMARY:

As a result of the countless economic activities that degrade the environment, several works
and studies have been presenting and proposing alternatives for the recovery and evaluation of
these degraded areas. The present study, using an ecological model, sought to integrate and
evaluate the recovery of an area degraded by cassiterite mining in the municipality of Itapua
do Oeste - RO, based on the phenomena that compose the chemical elements of the soil and
biological factors such as vegetation. Based on the General Theory of Systems, it applied an
ecological model that sought to evaluate the system as complex and dynamic, where the soil
being one of the main conditions of stability of the terrain. Considering terrain as a very
sensitive element mainly for the initial development of the system, it was considered the
initial preparation of the soil with a cocktail of forage plants of the leguminous family to
leverage the environmental recovery. A historical series of 10 years of analysis of fertility of
the soil component and development of the vegetation component and the current state of the
area regarding vulnerability to erosion was evaluated. These components have a great
influence on the maintenance of matter and energy in the system or degraded area. It sought to
have as reference the environment of the Secondary Forest (Capoeira) and Primary Forest
(Mata) surroundings, buying the results of the data collected in the field, using the Degraded
Areas Recovery Program (PRAD) as a model implemented in Mina Novo Mundo since 2005.
it is known that the concern with soil recovery generated a dynamic and evolutionary system
where cause and effect phenomena made the system capable of feedback, which guarantees
the system the capacity to internalize flows. Ensuring the entry and development of plants,
featuring the proposed ecological model and the use of geoprocessing technologies in
determining the current state of the system regarding vulnerability to erosion. It was
concluded that the results achieved using the ecological model expressed the degree of
complexity that already exists in the New World Mine and its capacity to support the internal
flow and maintain its feedback. The purpose of this work is to show that techniques for
recovering areas degraded by mining, using ecological models is a great alternative in
PRAD’s.
