The results showed that soil compaction had the strongest ability to increase risk of heavy metal mobility. Recreational activity caused a 2-3-fold increase in the density of the soil, resulting in poor aeration and significant heavy metal contamination, affecting the stability and functioning of the green spaces. Moreover, the proximity of the urban environment had a negative effect on the state of the stand. The maximum heavy metal migration capacity determined by biological uptake was found in the root systems of 70-80-year-old oak tree stands and the minimum, in the roots of pine and birch phytocoenosis. The systems’ normal functions were hindered due to reduction in microbial activity.</abstract><trans-abstract xml:lang="ru">В условиях уникального лесного массива - Лесной опытной дачи Российского государственного аграрного университета - МСХА имени К.А. Тимирязева изучен в динамике комплекс почвенно-экологических показателей в системе почва-растение с использованием физических, химических и биологических (микробиологических) параметров на фоне загрязнения тяжелыми металлами (ТМ) и нерегулируемой рекреации. Исследования показали, что уплотнение почвы выступает мощным негативным фактором, вызывающим сенсибилизационный эффект, при котором увеличивается опасность действия тяжелых металлов. Возросшая рекреационная нагрузка, вызывающая 2-3-кратное возрастание плотности почвы, а также ее аэрорегулируемость на фоне существенного загрязнения тяжелыми металлами, вызывает комплекс факторов, негативно влияющих на устойчивость и функционирование «зеленых легких». Кроме того, с увеличением антропогенной нагрузки миграция ТМ в растения увеличивается. Максимальная миграционная способность установлена в корневой системе 70-80-летних древостоев дуба, минимальная - в корнях сосново-березового фитценоза. Нормально функционирование экосистемы было нарушено вследствие снижения микробиологической активности.</trans-abstract><kwd-group xml:lang="en"><kwd>heavy metals</kwd><kwd>compaction</kwd><kwd>microbiological activity</kwd><kwd>soil ecological functions</kwd><kwd>living conditions of a forest stand</kwd><kwd>recreational load</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тяжелые металлы (ТМ)</kwd><kwd>уплотнение почвы</kwd><kwd>микробиологическая активность</kwd><kwd>экологические функции почвы</kwd><kwd>жизненное состояние древостоя</kwd><kwd>рекреационная нагрузка</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Cheng Z., A.
