06.00.00 Agricultural sciences
Description
Petrovsky garden was founded in 1703 and is the most important historical object of landscape architecture in Petrozavodsk. Tikhon Balandin made a description and drawing of Petrovsky garden at the beginning of the 19th century. He completed his work by studying and measuring the fragments of the earthen fortress, blast furnace and the location of the destroyed palace, pond and birch garden. On the basis of the historical documents, we created a 3D model of Petrovsky garden using of modern computer-aided design. Threedimensional model of the garden allows viewing the object from different angles, gives an idea about structure and compositions of the garden on a new visual level. Some examples of visualization garden fragments were presented at the article. Now the garden doesn’t have its original structure. The historical garden layout and 3D model of object can be used for reconstruction of Petrovsky garden

ANALYSIS OF SPATIAL STRUCTURE AND CONDITION OF STANDS IN “YAMKA” PARK OF PETROZVODSK
06.00.00 Agricultural sciences
Description
The article presents the results of the evaluation of the spatial structure and condition of trees and shrubs in different types of park stands located in the park called “Yamka” in Petrozavodsk. Features of planning and spatial distribution of trees and shrubs have been identified. The species and number of plants in good, satisfactory and unsatisfactory states were determined. The conducted analysis of species distribution and the number of trees and shrubs in each category of state allows suggesting the activities for reconstruction of park stands

APPROBATION OF THE SUBSTANTIATION METHODS OF THE INTERNATIONAL TIMBER TRANSPORTATION PROCESS
Description
Modern small logging enterprises exporting timber primarily by lorry transport do not have resources for implementing research that contributes to reducing the cost of this type of transport. Besides, there is no universal and accessible planning methodology and operative decision-making in the organization of timber export by lorry transport. Because of this, the author of the article has proposed a methodology for improving international timber transportation by timber trucks. This methodology contains logging modeling simulation, as well as analysis and contain of different options of logging. Within the framework of this methodology, a unique model based on the discrete event simulation has been developed. This model simulates a full cycle of timber transportation from the terminal to several foreign consumers. The working capacity of the model was verified by simulating several export scenarios based on data obtained during field study at one of the logging enterprises, the annual logging volume of which is 400 thousand cubic meters. The analysis and comparison of the modeling results have confirmed the possibility of using this methodology in planning and organizing international timber transportation for small logging enterprises
