Abstract

This paper provides information about the background, process and results of growth modeling, yield and bioproductivity of artificial (planted) pine stands in urban forests in the city of Kyiv. This topic is exceptionally important to ecological functions of urban forest ecosystems around Kyiv, like any other urban forests, in terms of maintaining sustainability of the internal environment of cities, improving the environmental situation and reducing harmful effects of industry, transport, etc. A characteristic feature of urban forests is a substantial anthropogenic pressure on forest ecosystems, which is much higher compared to production forests. As a rule, reference information, growth models, etc. for urban forests are either weak or completely absent. This work is designed to eliminate some of such shortcomings and problems for forests around the biggest city in Ukraine. As a major result of the study, models of growth and biological productivity dynamics of live biomass, Net Primary Production have been developed. We show specific features of growth and functioning of urban forests and therefore a need for the development of a special reference and normative base for inventory and management of this category of forests.
