Таксаційні характеристики та життєвий стан деревних рослин санітарно-захисної зони ПАТ "Український графіт"

Abstract

Наведено дані з видового складу насаджень санітарно-захисної зони ПАТ "Український графіт", розподіл рослин за висотами, діаметром та фітосанітарним станом. Деревні насадження подані 29 видами, що належать до 18 родин, серед яких найчисельнішими виявились Fabaceae Lindl. та Ulmaceae Mirb. Зазначено, що найбільшою є група рослин, висота яких змінюється від 18,1 до 20,0 м. Переважають рослини, діаметр яких варіює в межах 28,1-32 см та 100,1-104 см. Фітосанітарний стан насаджень задовільний. Санітарно-захисна зона ПАТ "Український графіт" потребує планомірної реконструкціїThe research of species composition and life conditions of green spaces on the plantations of the sanitary protection zones, distribution of plants by height, diameter and the phytosanitary conditions is important to solve the existing environmental problems. It is necessary to conduct an inventory of green plantations using the data, which might help with the process of bringing them up to date. We conducted the research at the cite of a tree plantation inside the sanitary protection zone of the "Ukrainian Graphite" PJSC. The inventory was conducted in accordance with the instruction of technical inventory of green planting in the cities and urban villages of Ukraine. Assessment of the of plants' condition was carried out using a scale by H.G. Yakubov (2005). The index of living conditions of a tree stand and its damage was calculated using Alekseev formulas. In the course of study we have found out that Plantations of trees are comprised of 29 species in total, belonging to 18 different families, the most numerous of which are Fabaceae Lindl. And Ulmaceae Mirb. The most numerous is the group of plants the height of which ranges from 18.1 to 20.0 meters. Plants with a diameter that varies between 28.1 – 32 cm and 100.1 – 104 cm appear to be dominant. No signs of weakening were observed in a 7.58 % of the total number of plants in the research plot. Symptoms of moderate weakening (category I) were observed in a 61.37% of the total amount of trees. The most numerous in this category were plants of such species as Robinia pseudoacacia L. and Ulmus carpinifolia Rupp. Phytosanitary condition of plantations is satisfactory. Thus, we may conclude that the sanitary protection zone of the "Ukrainian Graphite" PJSC is in dire need of systematic reconstruction of the green plantations with the aim to boost its ecological impact on air purity, but also for the sake of its architectural and aesthetic value.
