摘要

摘要本研究的目的是评估乌克兰境内自然区白杨林的现状和生产力，并确定其用于人工林种植的前景。研究对象是乌克兰森林中的白杨树，生长在不同自然区，即Polisya（乌克兰森林区）、森林草原和草原，面积超过7600公顷。这项研究是在分析森林清查数据（乌克兰森林基金数据库）的基础上进行的，该数据包含给定的林分特征，如起源、年龄、直径、高度、森林场地条件类型等。通过按年龄对地块进行分组来估计特征。根据开发的表格，分析了白杨林分的生长特性（主要测定特性的动态）和生产能力。研究发现，白杨林主要集中在乌克兰的草原和森林草原。林分为矮林或人工林；它们生长在潮湿肥沃、新鲜肥沃和潮湿肥沃的地方。由于乌克兰境内所有自然区年龄超过40岁的白杨林占显著优势，白杨林的年龄分布严重不平衡。生产效率更高的是生长在Polisya和森林草原内的白杨林。在规划和优先考虑白杨林的相关林业干预措施时，应使用制定的生长和生产力表。

White poplar (Populus alba L.) stands in Ukraine: the current state, growth specificities and prospects of using for forest plantations

Abstract The aim of the study was to assess the current state and evaluate the productivity of white poplar stands by natural zones within Ukraine and to define the prospects for their use for plantation forest cultivation. The objects of the study were white poplar stands in Ukrainian forests grown on the area of more than 7,600 hectares in various natural zones, namely Polissya (forest zone in Ukraine), Forest-Steppe, and Steppe. The study was carried out based on the analysis of forest inventory data (Ukrainian forest fund database) containing given stand characteristics such as origin, age, diameter, height, type of forest site conditions, etc. The characteristics were estimated by grouping the plots by age. The growth specificities (dynamics of the main mensuration characteristics) and the productive capacity of the white poplar stands were analyzed based on the developed tables. It was found that white poplar stands are mainly concentrated in Steppe and Forest-Steppe in Ukraine. The stands are of coppice or artificial origin; they grow in moist fairly fertile, fresh fairly fertile and moist fertile sites. The age distribution of the white poplar stands is severely imbalanced due to a significant predominance of stands aged over 40 years in all natural zones within Ukraine. More productive are the white poplar stands growing within Polissya and Forest-Steppe. The developed growth and productivity tables should be used when planning and prioritizing the relevant forestry interventions in white poplar stands.
