System of measures for improvement of recreation potential and sustainability of urban forest
Developing a system for conservation, sustainability and recreational capacity of urban forest was conducted taking into account the structure of forest landscapes, the degree of disturbance of forest ecosystems, the indicators of recreational load and functional purpose plots and arrays of urban forests. When defining a set of measures, the degree of disturbance of forest landscape is taken into account as the main indicator of differentiation of the entire system, preempting the mode and intensity of agriculture in urban forests. The Green Fund of Tomsk city as the most important environmental factor of the living environment is a collection of urban land with the presence of live vegetation from trees and herbaceous plants in natural and artificial origin, including urban forests. For proper organization and management practices in urban forests a provision or regulation of the citys green fund use is required, in which a proper modern legislative framework determining the legal status of the fund balance inventory of individual objects, forms of ownership and use, administration and management, protection and reproduction, the environmental potential assessment should be given. In the course of field studies and laboratory works analysis was carried out of the plantations, proposals were developed for a sustainable protection of forest stands: species, technologies, volumes and cost cutting and reconstructive planting within the sanitary protection zone, as well as advice on gardening the territory around the plant. However, the sanitary protection zone of the Tomskneftekhim (Tomsk Oil and Chemical Plant) is not separated from the buffer zone of the Siberian Chemical Plant, where it resides; it has not been approved legally; and it is not included in materials management. The results obtained in the study of urban forests in Tomsk indicate long-term lack of care and, consequently, need to develop a system of forestry measures to optimize the health of urban forests. It is important to provide the relevant scientific evidence for these recommendations. Thus, for landscaping the urban area it is crucial to study in detail the conditions for growing plants in a suburban environment, find the right system of care for plants and carry out the selection of species with appropriate ecological features, as well as valuable aesthetic and architectural qualities.
