Les Structures Spatiales de l'Est Algérien. Les maillages territoriaux, urbains et routiers.

Abstract : The regional analysis is an investigation very complex due to the definition that, a region consists on some irregular and complicated parameters which are sometimes visible and other time invisible, and also mobile or immobile but in continuous and interdependent relation. Gathering all the spatial components is almost impossible, however a consideration should be taken towards some factors that are essential and decided. These lead to emphasise on some principal split up and spread out characterising any site or region.
One of the main aims of this study is to define or to find out for an approch between the previous spatial confirmation and the actual one, across the oriental part of Algeria or "Eastern Algeria".
Based on three types of meshs or networks, which are scaled as follow:
+ The region or site with its equivalent "wilaya or communes in the algerian administrative way;
+ The urban netmork;
+ The netmork system of communication or connection including rail-tramways...
Every type of these systems has been submitted to a dtailed study and evolution, starting from almost the antic time until the present. Results have led to a typical system of configuration, which has been correlated to some theorotical models by using some modern tools of investigation.
As a result, we found that what ever is a system of meshs or netmork taken in consideration, the eastern part of Algeria "Est Algérien" has demonstrated a typical exemple of a space which present some distinguishable shappes opposite to each other, whatever is the used method. Conséquently, we concluded that the region "Est Algérien" is dominated by two combined or coupled spatial systems:
+ A classical and traditionnel system, characterising the marginal areas (oocidental part off the Tell, south part of the hight lands "hauts plateaux", the Nememcha area, the Hodna basin and the Saharien Atlas) show most of the time a delay up and a split up concerning differents fields;
+ Owning to the colonial power, another system has been created or noticed; it concerns the linear polarisation along the main systems of communication.
Consequently, in fact the model is concerned with an anisotropic area presenting a succession of forms which are gratuated in polarised pseudo-areas located arround the essential civic centers (centres urbains) and well connected by the presence of communication ways along a preferential axis. Moreover on each part of this main system, some spatial pseudo-systems have been subsisted and lasted.
