GEOSSISTEMAS (Geosystems)
Abstract
O presente artigo mostra a evolução e as características da visão sistêmica ou holística em Geografia. Ressalta que a “PAISAGEM” é a fisionomia do próprio GEOSSISTEMA resultado da estrutura dos elementos. O Geossistema apresenta três entradas segundo Bertrand (l978): a) a naturalista, b) do território dos homens, c) a cultural, somando-se ainda o elemento “tempo”, linear ou cíclico. Acrescentamos o tempo antrópico ou de impactos. Como na Biologia, face à diversidade espacial, o autor insiste no emprego do termo GEODIVERSIDADE pelos Geógrafos (Troppmair, 2000). O estudo conclui com um MODELO de Geossistema que mostra a intensidade das inter-relações dos elementos naturais e antrópicos.

ABSTRACT
This paper shows the evolution and the caracteristics of the systemic or holistic view of GEOSYSTEMS. It affirms that LANDSCAPE is the face of thegeossystem refleating the structure and the diversity of elements. The geosystem has 3 entrances a) the natural, b) the human space c) the culture space, associated with the element “time”, linear or cyclic (Bertrand, 1978) and we add the antropic or impact time. How in Biology due the spatial diversity the author insist on the term “GEODIVERSITY to be used by geographers (Troppmair, 2000). The paper finished showing a MODEL of geosystemic integration with different intensivities very intensif, intermediate, weak and imperceptible.
Key Words: Systems, Geosystems, Landscape, Geodiversity, Models.
