Лесная подстилка оказывает влияние на такие процессы, как поступление питательных веществ, формирование гумуса, накопление углерода, частотность появления возгорания. Годовая динамика подстилки характеризуется увеличением его количестве к концу сухого периода и тесно связана с дождевым сезоном. Основными факторами, влияющими на процесс разложения подстилки в лесах являются температура и влагосодержание, а также различные микроорганизмы. Разложение подстилки в лесу является важным фактором переноса СО2 из леса в атмосферу. Очевидно, что такая зависимость скорости выделения СО2 приводит к сезонно-зависимой оценки величины выделяемого СО2 в лесах. Вместе с тем, существуют усредненные модельные оценки разложения массы подстилки в лесах за год. Плотность дерева отрицательно влияет на скорость выделения СО2 при разложении древесной массы. С учетом вышеизложенного рассмотрен вопрос об усредненной оценки скорости выделения СО2 из подстилки на лесных участках, где меры по сбору и обработке подстилки не осуществляются.</p><p>Исследованы два вопроса: (а) вопрос о наличии такой оптимальной функциональной зависимости скорости экспоненциального разложения подстилки от ее исходной массы при которой, суммарная оставшаяся масса подстилки достигает минимального значения. Показано существование такой оптимальной скорости, которая прямо пропорциональна логарифму исходной массы подстилки. Также исследован вопрос о зависимости скорости выделения СО2 при разложении подстилки от исходной массы подстилки. Проведенный анализ показал, что при вышерассмотренном оптимальном режиме такая зависимость отсутствует.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the assessment of functional indicators of litter decomposition in forest areas. Forest litter influences processes such as the intake of nutrients, the formation of humus, carbon accumulation, and the frequency of ignition. The annual dynamics of litter is characterized by an increase in its quantity by the end of the dry period and is closely related to the rainy season. The main factors affecting the decomposition of litter in forests are temperature and moisture content, as well as various microorganisms. The decomposition of litter in the forest is an important factor in the transport of CO2 from the forest into the atmosphere. It is obvious that this dependence of the CO2 release rate leads to a seasonally dependent estimate of the amount of CO2 released in forests. At the same time, there are averaged model estimates of the decomposition of litter mass in forests per year. The density of wood negatively affects the rate of CO2 release during the decomposition of wood pulp. Taking into account the above, the issue of an average estimate of the rate of CO2 release from litter in forest areas where litter collection and processing measures are not carried out is considered.</p><p>Two questions are investigated: (a) the question of the existence of such an optimal functional dependence of the exponential decomposition rate of the litter on its initial mass at which the total remaining mass of the litter reaches a minimum value. The existence of such an optimal velocity is shown, which is directly proportional to the logarithm of the initial mass of the litter. The question of the dependence of the CO2 release rate during the decomposition of the litter on the initial mass of the litter is also investigated. The analysis showed that there is no such dependence in the above optimal mode.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>подстилка</kwd><kwd>лес</kwd><kwd>разложение</kwd><kwd>оптимизация</kwd><kwd>лесная экосистема</kwd></kwd-group><kwd-group xml:lang="en"><kwd>litter</kwd><kwd>forest</kwd><kwd>decomposition</kwd><kwd>optimization</kwd><kwd>forest ecosystem</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">Liu W., Schaefer D., Qiao L., Liu X.
