Cultivation of the Targeted Forest Plantations

Abstract

Targeted reforestation refers to ecosystems with natural and artificial energy reserves. Additional energy reserves are spent on grow-ing and harvesting, various types of forest care, forest use, and delivery of products to consumers, including energy costs for all types of preparation. The wood to be harvested must be assessed on the energy consumption required for its production. The purpose of this work was to develop a comprehensive methodology to assess the energy effect, model the process of plantation operation considering the soil type, tree species, and technical parameters of operating machines. According to the estimation results of the trunk wood energy value, it has been established that depending on the growth rate and maturity level, the target plantations are divided into two types, which should be taken into account during planting and subsequent rotation. It is shown that with regard to the technological features of machine sys-tems and the type of plantation, it is necessary to consider dimensional characteristics of the planting scheme and the technological cycle of exploiting the forest plantation. The results of mathematical modeling following the technological parameters of operating machines and all types of costs showed that the cost of the selected target species for reforestation can provide sufficient profit when optimizing the machine system operations. The principle of modular division of machines system on power, technological, and transport modules is offered, which vary in purpose, criteria of parameters optimization, and indicators of work. The obtained mathematical model and meth-odology of target planting optimization can be applied in forestry and agricultural complexes, as well as become the basis for further research in this direction.

A Comprehensive Assessment of Forest Transport Network Planning Taking into Account the Project's Technical, Economic, Environmental, and Social Aspects

“…Each category has its own set of rules for managing and using the forest, and a network of forest roads is used to ensure that these rules are followed. The current state of the forest transportation network determines when finished products are removed from the forest when forestry work is scheduled, when planting materials, machinery, and workers are delivered on time to the work site, and when firefighting supplies arrive on time to prevent and fight forest fires [17][18][19]. The spatial configuration and element-by-element components of the forest road network differ depending on the type of forest in which it is located [20].…”
