dc.description.abstract | Changing the floristic component is particularly interesting in the agroecosystem. In arid areas, the introduction of cropsunder pivot, induced floristic diversity is significant. Our work lies in the impact of introductions of plant species on the floristic composition of biodiversity after the establishment of a crop under pivot followed by a stop. For this, we used three pivots at different ages of abandonment: 01 year, 02 years and 3 years at the region of Hassi Ben Abdallah in Ouargla. Surveys conducted during the sampling period, from the month of February (2005) until March (2005), led to inventory 22 species distributed in 10 botanical families. The analysis of results highlighted the predominance of the species Bromus rubens in three study sites, with a very high degree of presence. In addition, stations 1 and 2 show a low floristic diversity compared to station 3, which reflects a wide variation in the floristic component, it is probably related to the age of abandonment and human actions. | en_US |
