Optimization of a spatial organization city protective greening

The urgency of inclusion in the system of territorial planning and ecological zoning of the procedure of assessment of environmental protection efficiency of green plantations in the context of the task of creating a comfortable and safe urban environment is substantiated. It is determined that the sanitizing efficiency of environmental gardening is an indicator of the ratio of the magnitude of the positive result achieved for a specific period of time (assimilation and neutralization of toxicants) and costs. An analysis of the known methods for assessing the quality of green areas has been carried out, criteria and assessment indicators have been identified, the author's approach has been identified, which involves calculating the optimal distance of the plantation strip from the object of aerotechnogenic impact, taking into account the value of the dangerous wind speed and the technical characteristics of the emission source. An illustrative example is provided. Provisions are formulated that are advisable to take into account when developing managerial decisions: aimed at improving the quality of urban gardening. The effectiveness of plants is manifested locally, therefore, it is necessary to take into account the nature of priority substances (markers), the effect of the summation of their action, migratory properties, as well as the technical parameters of the emission source.
