Resumo
The delimitation of Permanent Preservation Areas (PPA) frequently consider only the channel’s boards in function of its large,
and not others important kinds of geomorphological features as the hillslope’s top and its sequences, the top line of water
divisor, the board zone of high tabular or plateau surfaces and the high slope sectors, as well determine the environmental law.
The application of the law intends, commonly, an important preservation area but sometimes the law is not available because the calculus is complicated by consequence of concept interpretations of the geomorphological and pedological terms witch
involve geomorphological and pedological concepts needing more discussion. This article result from one study case developed
in João Leite microbasin, located near Goiânia city, over its green belt, state of Goiás, in order to illustrate this problem. There
the total of these others areas is bigger than the correspondent areas of marginal boards, and take about 70,5%, in average, of
the microbasin, except high slope (33%), mostly under unauthorized use, indicating that these abiantal rules should be considered
in unabrogatory unuse.
