Abstract

The influence of anthropogenic activity on the quality of urban alluvial soils and conditions of growth and state of tree stands is estimated. The level of negative consequences for natural components is correlated with the degree of human effect. Moisture decreases, the humus content changes in different directions, and the pH of water and electrical conductivity increase in the soil profile. Soil densification and the inhibition of biological activity are recorded in the surface horizons. The coefficient of ecological state of soils decreases by 6–24% compared to the optimum conditions. The correlation analysis showed a significant weak inverse correlation between the state of vegetation and soil quality (the Spearman coefficient was –0.53).

城市公园休闲景观中土壤和植被的生态状态（以莫斯科的凯瑟琳公园为例）

摘要

估计了人为活动对城市冲积土壤质量以及树木生长状况和林分状况的影响。天然成分负面影响的程度与人类影响程度相关。水分降低，腐殖质含量向不同方向变化，土壤剖面中水的pH值和电导率增加。在表层记录了土壤致密化和生物活性的抑制。与最佳条件相比，土壤生态状态系数降低了6-24％。相关分析表明，植被状况与土壤质量之间存在极弱的反相关关系（Spearman系数为–0.53）。
