   <abstract xml:lang="ru">
    <p>Эксергия была введена в качестве определителя состояния, структуры и функции экосистемы. Эту величину можно представить в двух ипостасях: первая - энергия, накопленная в экосистеме, вторая – ее деградация и образования энтропии. В настоящее время понятие эксергии в экологии используется для переопределения дарвиновского принципа «выживания сильнейших» в «экологическую термодинамику», согласно которому самая приспособленная экосистема способна использовать и сохранять потоки энергии и материалов наиболее эффективным образом. Возникает необходимость адекватно рассчитывать эксергию экосистем, так как информация об этой характеристике позволяет не только управлять экосистемами в ближайшей перспективе, но и прогнозировать возможности экосистем а противостоянии с современными угрозами их целостности и адаптации системам к этим вызовам. Важность практического расчета эксергии в связи с вышесказанным не подлежит сомнению. Наряду с известной практикой расчета эксергии живых организмов, использующих генную структуру необходимо иметь альтернативные способы расчета эксергии. В работе предлагается альтернативный метод расчета эксергии лесных экосистем, который содержит как элементы традиционного подхода к расчету эксергии, так и новые положения, связанные с использованием эколого-физиологических моделей динамики роста древостоев</p>

   <trans-abstract xml:lang="en">
    <p>Exergy was introduced as a determinant of the state, structure and function of an ecosystem. This value can be represented in two hypostases: the first is the energy stored in the ecosystem, the second is its degradation and entropy formation. Currently, the concept of exergy in ecology is used to redefine the Darwinian principle of &quot;survival of the fittest&quot; into &quot;ecological thermodynamics&quot;, according to which the most adapted ecosystem is able to use and conserve flows of energy and materials in the most efficient way. There is a need to adequately calculate the exergy of ecosystems, as information on this characteristic allows not only to manage ecosystems in the short term, but also to predict the capacity of ecosystems to withstand current threats to their integrity and adapt systems to these challenges. The importance of practical calculation of exergy in connection with the above is beyond doubt. Along with the known practice of calculating the exergy of living organisms using gene structure, it is necessary to have alternative ways of calculating exergy. This paper proposes an alternative method for calculating the exergy of forest ecosystems, which contains both elements of the traditional approach to exergy calculation and new provisions related to the use of ecological and physiological models of stand growth dynamics</p>
