Assessment of ecological functions forest ecosystem in the conditions of a metropolis (on example of the Forest experimentation station of the RGAU-MSHA named after K.A. Timiryazev

The article considers the assessment of the ecological functions of the forest ecosystem in various variants of the mesorelief in combination with environmental factors. The influence of complex indicators on the dynamics of changes in ecosystem services located on the territory of the northern district of Moscow. The influence of complex indicators on the dynamics of changes in ecosystem services located on the territory of the northern district of Moscow. Ecological functions are evaluated such as, conditions of the stand of trees, percent projective ground cover, quantity and quality of wood litter which affects the formation of the litter. The index of similarity of the species composition of the forest stand is calculated in five sections of the transect and the index of species richness and diversity of biocenoses is estimated. It has been established that environmental indicator affect diversity of the urban forest depending on the location in the mesorelief.
