ABSTRACT:
This aim of this
study is to highlight the critical view of human action and anthropic at
the steppe zone of Tlemcen. Therefore, the current paper tends to tackle an
analytical study of the dynamics of ecosystems in both states: El-Gor in the
south-east and El-Bouihi in the southern-west of Tlemcen. To carry out this
study it was necessary to present the bioclimatic context based on weather data
to perform bioclimatic syntheses (diagram ombrothermic, climagramme rainfall
Emberger). By comparison between old and recent periods (1913-1938) and
(1984-2009), respectively, for the region of El-Gor and (1913-1938) and
(1970-1990) for the El station-Bouihi, there is a net decrease in rainfall and
higher temperatures at the new periods, which means that the study areas are moving towards the driest
floors. The interpretation of multidimensional treatments AFC (Factor
Analysis of Correspondences) vegetation helps to determine the existing
affinities between the different taxa. These biostatistical analyses help to
highlight the different factors often responsible for the dynamic regressive
most cases.
