Abstract

The main trends in the dynamics of vegetation restoration on unevenly aged terraces of the Tyrnyauz Combine tailings dam in the conditions of the Bylym Arid Depression over a 50-year period are revealed. The steppe meadow regenerates on young upper terraces for 20 years. The slowest process is the self-growth of old-growth terraces at the dam foot (50 years). Conversely, the processes of soil formation are more intensive on the lower terraces. The phytocenogenetic process has not yet been completed at the tailings dam to date. It is predicted that subalpine steppe meadows will form on dark humus soils on the dam embankment exposed to low anthropogenic pressure.

Bylym干旱洼地（中部高加索地区）技术景观中植被恢复的长期动态

摘要

揭示了在Bylym干旱低气压条件下Tyrnyauz联合尾矿坝不平龄梯田50年间植被恢复的主要趋势。草原草甸在年轻的上层梯田中再生了20年。最慢的过程是坝脚（50年）上的旧梯田的自生。相反，在较低的阶地上，土壤形成的过程更加密集。迄今为止，尾矿坝的植物致植物过程尚未完成。预计在人为压低的堤坝上，深色的腐殖质土壤上会形成亚高山草原草甸。
