A series of sample plots have been laid to study the influence of recreational load in general and in grassy ground cover in Central Park of Culture and Leisure of Voronezh, Arboretum of Voronezh State University of Forestry and Technologies named after G F Morozov. We used qualitative (structural biodiversity) and quantitative (relative projective cover, abundance and constancy) estimation parameters as indicators of the species’ participation in the formation of plant associations using two urban ecosystems as an example. The aforementioned arboretum and park belong to the forest-park part of the city green zone. Tracing of flora synanthropization is very important here. Species abundance is generally higher in the arboretum (226 species), but grass cover is not numerous (31 species) due to timely economic activities. By quantitative parameters, on the contrary, grasses of broad-leaved forests prevail in the grassy cover of the Park: ashweed (Aegopodium podagraria L.) with projective cover (40-44.6%) and sedge (Carex pilosa Scop.) - 19.8% -29.6 % (1-2 stages of recreation, respectively). The class of abundance of these dominant species raises to 3 (1-2 for other species). The analysis of the constancy class, on the contrary, has not revealed clear species attachment to certain test plots.

在沃罗涅日文化和休闲中央公园、沃罗涅日国立林业科技大学植物园（以 GF Morozov 命名）中，已经铺设了一系列样地，以研究一般娱乐负荷和草地覆盖物的影响。我们以两个城市生态系统为例，使用定性（结构生物多样性）和定量（相对投影覆盖、丰度和恒定性）估计参数作为物种参与植物协会形成的指标。上述植物园和公园属于城市绿化带的森林公园部分。植物群协同作用的追踪在这里非常重要。植物园中的物种丰富度普遍较高（226 种），但由于经济活动及时，草覆盖并不多（31 种）。通过定量参数，Aegopodium podagraria L. ) 与投影覆盖 (40-44.6%) 和莎草 ( Carex pilosa Scop.) - 19.8% -29.6 % (分别为 1-2 个娱乐阶段)。这些优势物种的丰度等级增加到 3（其他物种为 1-2）。相反，恒定等级的分析并没有揭示出明确的物种对某些试验地块的依附性。
