Статья посвящена построению универсальной модели скорости изменения площади лесных покрытий. Предложен вариант показателя скорости обезлесения, в котором площадь лесного покрытия в конце рассматриваемого интервала времени является функцией его длительности. Отмечено, что введение указанной функциональной зависимости приводит к универсальности вводимой оценки скорости процесса, так как появляется возможность оценивать не только процесс обезлесения, но и процессы лесопосадки. Проанализирован показатель усредненной по рассматриваемому интервалу времени скорости процесса обезлесения. Сформирована и решена задача вариационной оптимизации введенного усредненного показателя с учетом вновь введенного ограничительного условия применительно к вышеотмеченной функциональной зависимости. Вычислена конкретная оценка нововведенного усредненного показателя в виде смещаемой оценки по оси времени при наличии жесткой связи между конечными точками рассматриваемого временного интервала усреднения.

The article is devoted to the construction of a universal model of the rate of change in the area of forest coverings. A variant of the deforestation rate indicator is proposed, in which the area of forest cover at the end of the time interval under consideration is a function of the duration of the specified time interval. It is noted that the introduction of this functional dependence leads to the universality of the introduced assessment of the speed of the process, since it becomes possible to evaluate not only the deforestation process, but also the processes of forest planting. The indicator of the speed of the deforestation process averaged over the considered time interval is analyzed. The problem of variational optimization of the introduced average indicator has been formed and solved, taking into account the newly introduced restrictive condition in relation to the above-mentioned functional dependence. A specific estimate of the new averaged indicator is calculated in the form of a shifted estimate along the time axis in the presence of a rigid connection between the endpoints of the considered averaging time interval.
