摘要：The present study was focused on the assessment of the ecology status of two wadis Henna and Ziatine by the determination of the abundance and specific composition of nematode community. The effects of spatial variations of abiotic parameters on nematode community were also investigated. Physico-chemical parameters revealed an important spatial fluctuation between the two wadis. The electric conductivity, current speed and suspended matter were the more fluctuating parameters. The granulometric study revealed that wadi Henna is characterized by a substratum composed with fine sedimentary particles, showed the highest content of organic matter and total nitrogen. The average density of nematode revealed a pronounced variation between the two wadis. Thus, wadi Ziatine was clearly more populated than wadi Henna. Significant difference.
