Types of hole-meadow and wetlands vegetation in oil-contaminated soils Siyazan district (Azerbaijan)

Considering the very important role of the environment and ecology in ensuring the health and food security of the population, Azerbaijan is implementing a consistent and effective state policy towards protecting the ecological balance. Improvement and protection of the ecological situation and the desire to minimize environmental pollution are the main directions of the policy of our state in this direction. Phytoecological studies and studies on oil-contaminated soils are today one of the most urgent environmental problems in Azerbaijan. Therefore, when sampling soil at the Siyazanneft mines in the Siyazan district, the species composition of phytocenoses in contaminated areas was determined. In the conducted research work, the species composition and structure of the primal-meadow and wetland vegetation common in the selected samples and areas (around oil wells) were studied. The results of phytoecological studies were used in the “Classification of Vegetation”. Thus, the vegetation found on the oil-contaminated lands of Siyazanneft was classified into 2 types of vegetation and 4 associations belonging to 2 formation groups. In the presented article, a research work was carried out on the phytoecological characteristics of the spring-meadow and wetland type of vegetation in the oil-contaminated territory “Siyazanneft”.
