Abstract

The objective of this study was to see the effect of the bioclimatic stage on certain characteristics of the soils of the forests of western Algeria.

For realized this work have selected three forest areas populated at 90% by Aleppo Pine and located in the bioclimatic stages humid, semi arid and arid. For each station, some physical, chemical and microbiological analyses were carried out that could have an impact on the vegetation and the biological processes of the soil.

The results showed that there is a great heterogeneity between the different stations and that the water and nitrogen content depends on the aridity gradient. On the other hand the amount of carbon is more important in the humid and arid zone and lower between the two stations. Regarding microbial biomass have noted that it does not depend on the aridity gradient. The enzymatic activities studied are more pronounced in the humid zone and almost the same in the semi arid and arid.

Keywords:
Basal respiration, microbial biomass, enzymatic activities, drought.
