Environment-forming role of black saxaul, Haloxylon aphyllum (Minkw.) Iljin in the Karnabchul Desert

Аннотация

The environment-forming role of desert tree plants has been studied in the light of A.A. Uranov’s concept of phytogenic field using the example of black saxaul, Haloxylon aphyllum (Minkw.) Iljin, in the Karnabchul Desert. It has been shown that the environment-forming influence of this species leads to considerable changes in the light regime, air and soil moisture and temperature regimes, and soil humus and salt contents within its phytogenic field. Consequently, pertinent changes take place in the dynamics of abundance and distribution pattern of the main plant species and wormwood–ephemeral vegetation.
