Имеются многочисленные подтверждения положительной связи продуктивности с биоразнообразием, особенно очевидной при взаимодействии двух комплементарных видов в локальных условиях, когда их смешение обусловливает продуктивность, большую по отношению к продуктивности чистых древостоев в тех те местообитаниях. Когда исследуется связь между продуктивностью и биоразнообразием на региональном и глобальном уровнях при взаимодействии десятков и сотен видов, названная положительная связь становится очевидной лишь на массовом эмпирическом материале. Поскольку известно, что хвойные и лиственные виды приспособлены к специфичным лесорастительным условиям и могут занимать разные экологические ниши, в настоящем исследовании предпринята попытка сравнительного анализа биомассы кедровых (Pinus koraiensis S. ex Z.) и дубовых (Quercus mongolica F. ex L.) естественных насаждений Приморья в контексте биоразнообразия. Леса Приморья характеризуются сложным породным составом, только в основном пологе может насчитываться до 15 и более пород, что осложняет определение из биологической продуктивности. Объектом исследования послужили кедровые и дубовые насаждения, заложенные соответственно на 12 и 14 пробных площадях в возрастном диапазоне от 35 до 200 лет. Сделан вывод об отсутствии значимого вклада доли основной породы в объяснение изменчивости биомассы ассимиляционного аппарата кедровых и дубовых насаждений, а также об отсутствии влияния обилия пород (количества пород в составе) на соотношение надземной биомассы кедровых и дубовых насаждений, что может быть объяснено недостаточным объемом фактического материала. Сравнение биомассы кедровников и дубняков в возрастной динамике показало, что в дубняках по отношению к кедровникам масса стволов больше на 17, масса ветвей на 53, надземная на 20 %, а масса ассимиляционного аппарата, напротив, меньше на 33 %. Таким образом, дубняки при меньшей массе ассимилирующих органов имеют большую массу ствола и ветвей. По-видимому, это происходит вследствие более высокой эффективности работы ассимиляционного аппарата дубняков. Полученные результаты могут быть полезны при оценке углерод депонирующей способности хвойно-широколиственных лесов Приморья.</p></abstract><trans-abstract xml:lang="en"><p>The relationship between biodiversity and the productivity of plant communities is one of the main directions in environmental research. There are numerous confirmations of a positive relationship between productivity and biodiversity, especially evident in the interaction of two complementary species in local conditions, when their mixing causes productivity greater in relation to the productivity of pure stands in the same habitats. When the relationship between productivity and biodiversity is investigated at the regional and global levels with the interaction of tens and hundreds of species, this positive relationship becomes apparent only on huge empirical material. Since it is known that coniferous and deciduous species are adapted to specific forest growing conditions and can occupy different ecological niches, our study attempts to compare the biomass of Pinus koraiensis S. ex Z. and Quercus mongolica F. ex L. natural forests of Primorye in the context of biodiversity. The forests of Primorye are characterized by a complex species composition, when only in the main canopy there can be up to 15 or more species, which complicates the determination of their biological productivity. The object of the study was Pinus koraiensis and Quercus mongolica natural stands, growing respectively on 12 and 14 sample plots in the age range from 35 to 200 years. It is concluded that there is no significant contribution of the share of the main species to explain the variability of the biomass of the assimilation apparatus of these species, as well as the absence of the influence of the species abundance (the number of species in the canopy composition) on the ratio of aboveground biomass of two species, which can be explained by insufficient volume of empirical material. A comparison of the biomass of two species in age dynamics showed that in Quercus mongolica forests, in relation to Pinus koraiensis forests, the biomass of stems is by 17, of branches is by 53, aboveground is by 20% more, and the mass of the assimilation apparatus, on the contrary, is by 33% less. Thus, Quercus mongolica stands with a smaller mass of assimilating organs have a larger mass of stems and branches. Apparently, this is due to the higher efficiency of the assimilation apparatus of Quercus mongolica. The results obtained can be useful in assessing the carbon-depositing capacity of coniferous-deciduous forests of Primorye.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Pinus koraiensis S. ex Z.</kwd><kwd>Quercus mongolica F. ex L.</kwd><kwd>биомасса насаждений</kwd><kwd>обилие пород</kwd><kwd>сравнительный анализ</kwd><kwd>регрессионные модели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pinus koraiensis S. ex Z.</kwd><kwd>Quercus mongolica F. ex L.</kwd><kwd>plant biomass</kwd><kwd>species abundance</kwd><kwd>comparative analysis</kwd><kwd>regression models</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дрейпер Н., Смит Г.
