Abstract
The bio-restoration project of the mercurial career of Guenicha operating in the region of Azzaba must not only take into account the potential of the site but also its integration into the surrounding landscape. To achieve this result we performed a qualitative estimation of the potentialities of the site to understand better the structuring of the space and these various affectations. We took into account the current occupation of grounds to locate the precious elements, the curiosities susceptible to remain constant in the landscape and to highlight sectors or zones of an exceptional fragility which we call sensitive sectors or zone where any intervention can influence the visual atmosphere of the landscape. The zoning allowed us to reveal two landscaped bulks represented by the plain of Azzaba and the career of Guenicha. At first time we identified their components. To increase the visibility of the site, we shall create the dominances which characterize them and we arrange the transitions between them. In the last we will link the study area with the surrounding landscape by offering the most sensible choice of a pardon to restore the soil and also achieve the integration with the surrounding landscape.
Highlights
Mining activities have impact on the environment
They are highly subject to erosion that may become a source of pollution for the whole region. Such a situation is typical of the region of Skikda. In this region there are deposits of mercury situated in the daîra of Azzaba where there is a factory of extraction of the ore the cinnabar
Method and means of study Our method is based on a study of zoning in the area several landscape units defined by the following criteria: - topography; - cover vegetable; - housing environment; - artificialisation – humanization; - hydrography; - visual quality
Summary
Mining activities have impact on the environment. Apart from the negative aesthetic impact, sites abandoned have neither land nor vegetation. Selection of views and their characteristics The choice of location and their number remains necessarily subjective, but requires the opening of the visual field that allows the observation of the landscape [13, 14] These views can be located both inside and outside the study site from communications paths, ridge lines, places of houses etc. Middle mountains: the case of career Guenicha The site of the career of Guenicha who was a former general appearance of conical hill with Front and Back (cuesta), is part of all the surrounding mountains This landscape unit is very characteristic and identifiable by its different components: topographic and visual exposure. The views are characterized by a wide range of views and simultaneous: - Over the whole of the plain north of Azzaba (Photo and 13 in figure 9); - On the mountains of djebels Safia el Hajar Koudiats Attail and the North - East (Photo in figure 9). - The forests and mountains of El djebels Ghedir, Dhira, Tenghout southwest (Figure in figure.9). - On forests Koudiat mzara, the Djebels Siafa Tenghout and south-east (Photo in figure 9)
