Abstract:

The article analyzes the impact of saline waters with chloride-sodium composition on the area of mixed forest. The water comes from the emergency exploration well. Comparative characteristics of the vegetation cover three experimental sites: a background site and sites with a strong and weak degree of salinity. It is shown that the total loss of trees comes even at low salinity and soil water content. The reduction in the overall richness and diversity of herbaceous vegetation is marked in disturbed areas. There are new species of plants that are resistant to salinity. Plants of the original forest community in the area with a strong degree of salinity are completely absent. The strong dominance of certain salt-tolerant species leads to a simplification of the spatial phytocoenosis structure. The monotony of the vegetation cover increases. The impact of mineralized water causes an indirect change in the whole range of environmental conditions. This leads to a profound transformation of the original forest vegetation type in the meadow or marsh, depending on the extent of flooding.
