Abstract :
[en] Introduction: The Copper belt of Katanga presents huge resources of Cu and Co-ore. On the copper hills, mineralized rocks outcrop and a specific flora did develop as a response to the high levels of Cu and Co in soil. Soil-vegetation relationships need to be understood in order to elaborate biodiversity conservation programs prior to industrial mining of the copper hills.
Literature: This paper reviews knowledge about soil characterization in the copper hills of Katanga and makes proposals for further research about the influence of the very specific chemical conditions of contaminated soils on the vegetation. The focus was put on the geochemical background and the bioavailability of Cu and Co. A lot of progress has been made recently about identification of soil-vegetation relationships.
Conclusion: However, the issue of Cu and Co mobility within soil-plant systems is not entirely solved. [fr] Introduction : L’arc cuprifère du Katanga regorge d’importantes réserves en cuivre et en cobalt dans son sous-sol. En plus de cette ressource, s’ajoute une diversité végétale spécifique aux sols des affleurements métallifères. Le fonctionnement des écosystèmes cupro-cobaltifères est étudié dans le cadre de l’élaboration et la mise en œuvre de programmes de conservation de la biodiversité préalables à l’exploitation minière des collines.
Littérature : Cette étude fait un état des connaissances sur les sols de l’arc cuprifère du Katanga et propose des pistes de recherches pouvant contribuer à la connaissance du fonctionnement de ce milieu aux conditions édaphiques inhabituelles. Sont principalement ciblés, le fonds géochimique et la biodisponibilité des éléments.
Conclusion : Même si les études actuelles ont permis d’importants progrès dans la connaissance des relations entre propriétés des sols et distribution dans l’espace des communautés végétales, la mobilité du cuivre et du cobalt dans ces systèmes n’est pas encore complètement comprise.
