Abstract

This study provides an analysis of the distribution of European larch in artificial forest stands in Ukraine. It was found that the potential area for the successful cultivation of this species can be not only the Western but also the Right-Bank and Left-Bank Forest-Steppe. The study has confirmed that European larch plantations, with the appropriate technology for planting and cultivation, are marked by rapid growth, high productivity and resistance. Under the forest site conditions of types C2, D2, and D3, in which the largest number of larch stands were built, a tendency was revealed towards an increased volume of stemwood with an increasing share of larch in the stand composition. Constructed regression models formalize this dependence. With advancing age, the influence of larch on an increase in the growing stock of plantations is reduced. Productivity and growth character of larch plantations in different types of forest growth conditions are different. European larch can form steady-state and highly productive plantations not only in fresh, but also in moist types of forest growth conditions. Under conditions of a fresh fertile site type (D2), as evidenced by the results of ANOVA, the share of larch in the composition of the stand has a significant impact on the main mensuration indices of the stand. The highest values for the average height are characteristic of larch with its significant share in the composition of plantations (6-10 units), and the highest values for the average stem diameter were observed with an average share of the species (3, 5-8 units). It is noted that the technology for the establishment and management of artificial larch plantations should be differentiated depending on the type of forest growth conditions by using optimal mixing and spacing schemes and appropriate silviculture regimes that regulate the share of larch in these stands. Keywords: European larch, forest plantation, forest stand, type of site conditions, stand composition

落叶松的分布、生长和生产力。乌克兰西部森林草原的种植园

本文对欧洲落叶松在乌克兰人工林中的分布进行了分析。结果表明，西部森林草原、右岸森林草原和左岸森林草原均可成功栽培。这项研究证实，欧洲的落叶松人工林在采用适当的种植和栽培技术的情况下，具有生长迅速、生产力高和抗性强的特点。在C2、D2和D3类型立地条件下，随着落叶松在林分组成中所占比例的增加，干材体积呈增加的趋势。构建的回归模型形式化了这种依赖性。随着林龄的增加，落叶松对人工林蓄积量增加的影响逐渐减弱。不同类型森林生长条件下落叶松人工林的生产力和生长特征不同。欧洲落叶松不仅可以在新鲜条件下，而且可以在潮湿的森林生长条件下形成稳定和高产的人工林。方差分析结果表明，在新鲜肥沃立地类型(D2)条件下，落叶松在林分构成中的比例对林分的主要测量指标有显著影响。平均高度最高的是落叶松，在人工林中所占的比例最高(6 ~ 10个单位);平均茎粗最高的是落叶松，在人工林中所占的比例最高(3,5 ~ 8个单位)。报告指出，应根据森林生长条件的类型来区分建立和管理人工落叶松人工林的技术，采用最佳混合和间距方案以及适当的造林制度来调节落叶松在这些林分中的份额。关键词:欧洲落叶松，人工林，林分，立地条件类型，林分组成

期刊介绍： The journal welcomes the original articles as well as short reports, review papers on forestry and forest science throughout the Baltic Sea region and elsewhere in the area of boreal and temperate forests. The Baltic Sea region is rather unique through its intrinsic environment and distinguished geographical and social conditions. A temperate climate, transitional and continental, has influenced formation of the mixed coniferous and deciduous stands of high productivity and biological diversity. The forest science has been affected by the ideas from both the East and West. In 1995, Forest Research Institutes and Universities from Estonia, Latvia and Lithuania joined their efforts to publish BALTIC FORESTRY.
