Abstract
The objectives were to: 1) analyze the physical-chemical variables of a site in
order to characterize the disturbed area’s suitability for planting; 2) detect
disturbed areas through spectral transformation techniques; and 3) generate
cartographic maps with the location of the disturbed areas suitable for planting.
The field data, Landsat TM 7 images, and digital elevation models were analyzed
with IDRISI and ArcView. Multivariate Cluster Analysis, and Principal
Components Analyses were applied to valuate the biometric and physicalchemical
variables of the soil, and detection of disturbed areas. Physicalchemical
analyses showed similar characteristics for the whole area in the study;
only soil depths are considered important for the establishment of forest
plantations. The combination of bands 3, 4 and 5 allowed detection of, in a
preliminary way, the disturbed areas. The Principal Component Analysis showed
that the first component reduced the dimensionality of the data while the second
component detected the disturbed areas.
Keywords: reforestation, disturbed areas, detection, spatial, Chihuahua, México.
1 Introduction
Worldwide, deforestation is associated with increasing demands for forest
products due to increased human populations [1]. Mexico has a deforestation rate
estimated at 600,000 hectares per year [2]. This is one of the highest rates of
