   <abstract xml:lang="ru">
    <p>Для семенных одновозрастных насаждений бука и дуба, лиственных семенных и порослевых пород, по опубликованным данным, по таблицам хода роста изученa скорость роста в высоту в одном и том же интервале возраста. Для установления темпов (скорости) роста использовались новые индикаторы – индексы. Предложены также новые коэффициенты для оценки типа рoста и доказана их пригодность для практического применения. Для этой цели они сравнивались с нулевыми натуральными показателями, которыми определялся до сих пор тип роста в высоту. Установлена при этом высокая степень корреляции. Сделан анализ темпов роста в высоту исследуемых нассаждений на основе их индексных кривых. Новые коэффициенты типа роста применены, и установлены значения и интервалы индексов скорости роста изучaемых насаждений для отдельных типов роста. Делается заключение о том, что коэффициенты типа роста, как и индексы скорости роста, являются удобными инструментами для установления разницы в скорости (темпе) роста и в типе роста лесных насаждений.</p>

    <p>Based on published data about the growth in height of model and other stands of seed-tree common beech, oak, deciduous and coppice deciduous stands have their rates of growth been investigated within one and the same age interval. New indicators have been used for establishing the respective growth rates – growth-rate indi-ces. New coefficients have been suggested for estimating the types of growth, and their applicability to use has been proved as these coefficients have been compared with the zero natural indicators of types of growth. A high level of correlation has been found with that. An analysis was made of the height growth rates of the studied stands based on their index curves. Further on, by applying the new coefficients of types of growth, the values and intervals of growth-rate indices according to types of growths, have been found for the stands of the tree spe-cies investigated. It has been concluded thatthe coefficients of types of growth, as well as the growth-rate indices, are rather convenient instruments for finding differences in the rates and types of the growth of forest stands in height.</p>
