Sensitivity of landscapes of the Cuchillas del Toa Biosphere Reserve.

Abstract

In the Cuchillas del Toa Biosphere Reserve there are carried out various socio-economic activities which must be developed in a very careful way and with scientific criteria, to avoid the spoilage of their natural resources. The need to study the sensitivity of terrestrial landscapes is evident, with the use of the theoretical-methodological conception of landscape geoecology, using the tools of geographic information systems. The complexity in the structure of the landscapes was verified with 15 first-order units, exposed to internal and external risk factors, which cause moderate instability in the units of the hypsometrically lower floors, and greater stability, in the most elevated zones. In general, landscapes are evaluated into moderately sensitive and very sensitive categories, with a wide incidence of anthropic factors.
