Inventory assessment of landscape objects Krasnoyarsk

The most promising approach to studying the quality of the urban environment in general, and its individual components, in particular woody vegetation, is the concept of environmental monitoring, which is based on the organization of a system of continuous observations, analysis and forecast of its state. The technological basis for monitoring the state of urban landscaping objects is a combination of biological and technical methods for obtaining information using selective research methods and a system for processing, analyzing and storing information using thematic and cartographic data banks and hierarchically subordinate, interconnected, adequately reflecting the ecological situation observed in the city indicators. Based on this, landscaping objects were selected – nine squares located in the city of Krasnoyarsk in territories with different levels of anthropogenic impacts, as close as possible to the observation posts for the state of the environment: “Lesok”, “Silver”, “Cosmonauts”, “Fabulous”, “Panyukovsky”, “Enthusiasts”, “Jubilee”, “Odessa”, “im. I. V. Surikov” and two control plots located in the green zone of Krasnoyarsk (Fruit and berry station and UZS nursery).
On the basis of generally accepted and author's methods, ecological passports of landscaping objects were formed. The environmental passport of the facility includes such sections as a situational plan, the balance of the territory of the facility, quantitative data on landscaping and qualitative characteristics of the state of vegetation and the road network, data on recreational load, calculations of the level of gas pollution and noise load from traffic flows on adjacent highways, fragments of which are presented in the article. The analysis of the received materials showed that: all the presented squares are objects of landscaping for general use and belong to objects of regional significance; the areas of these squares are in the range from 0.81 to 2.95 hectares, with the exception of the square "Cosmonauts", whose area is 6.96 hectares. At the same time, it was found that in squares with an area of up to three hectares, the zone of a comfortable environment can be only 9 %, in landscaping objects with an area of 7 to 20 hectares – up to 30 %, provided that the territories are compact, thus, in the square “Odessky” there is no comfort zone, because has an elongated shape and is located along the carriageway of a highway with heavy traffic (with freight traffic), Lesok Square – on the contrary, although it is small in size, it is located in a residential area away from highways, the Cosmonauts Square has the largest comfort zone due to the large territory and remoteness of its main part from the highway. The inventory assessment of plantings showed that the life condition of drooping birch and small-leaved linden in the city as a whole is estimated from “healthy” to “dying off”, the index varies from 100 to 15, naturally decreasing in critical growing conditions, the relationship of age, damage class with air quality allows the use of drooping birch and small-leaved linden as an indicator species for assessing aerotechnogenic pollution of cities, and this circumstance must be taken into account when creating urban plantations at landscaping objects with various technogenic loads.
