Комплексный оценочный показатель естественных и искусственных сосняков в ленточных борах Алтайского края

Комплексный оценочный показатель естественных и искусственных сосняков в ленточных борах Алтайского края

Abstract

Исследования проведены в Барнаульском ленточном бору на территории Рубцовского и Угловского административных районов Алтайского края. Сбор полевых материалов осуществлялся посредством метода пробных площадей в период с 2013 по 2017 гг. В ходе исследований была заложена 91 пробная площадь в искусственных и естественных сосняках различного возраста (от 13 до 120 лет), произрастающих в наиболее распространенном типе леса – сухой бор пологих всхолмлений. В отбираемых для исследования древостоях не проводились рубки ухода. В статье приведен фрагмент таксационной характеристики рассматриваемых сосновых древостоев естественного и искусственного происхождения. Найдены коэффициенты корреляции между значениями комплексных оценочных показателей древостоев различного происхождения и их средним возрастом, густотой и классами Крафта. Приведено распределение значений комплексного оценочного показателя по классам Крафта и график зависимости средних значений комплексного оценочного показателя от возраста древостоя. Установлено, что наибольшие значения комплексного оценочного показателя имеют деревья IV и V классов Крафта; также большие значения этого показателя у молодняков; до III класса возраста естественные сосновые древостои характеризуются большими значениями комплексного оценочного показателя по сравнению с искусственными. Комплексный оценочный показатель так же, как и распределение деревьев по классам Крафта, может служить для дифференциации деревьев по росту и положению в пологе и, как следствие, может быть использован в качестве объективного критерия для обоснования необходимости проведения лесохозяйственных мероприятий, в частности рубок ухода. The researches has been carried out in Barnaul line-wood on the territory of Rubtsovsk and Uglovsk administrative regions of Altay krai. Field materials collection has been accomplished by inventory-plots method in the period of 2013–2017 years. On the course of researches 91 inventory plots has been laid up in artificial and natural pine stands of different ages (from 13 to 120) growing in the widely spread forest type: gently scoping dry pine wood. Omprovement felling has not been carried out forest stands chosen for researches carrying out. The article contains a fragment of the taxation characteristics of the pine stands under consideration. Coefficients of correlation between values of complex estimating indexes of forest stands of various origin and their middle age, thickness and Kraft´s classes are found. Value distribution of a complex estimating index on Kraft´s classes and the schedule of dependence of mean values of a complex estimating index on an age of a forest stand is given. It is established that the greatest values of a complex estimating index characterize trees IV and V classes of Kraft; also great values of this index are characteristic of young growths; to the III class of an age natural pine forest stands are characterized by great values of a complex estimating index in comparison with simulated. The complex estimating index also, as well as distribution of trees on Kraft´s classes can serves for differentiation of trees on body height and situation in bed curtains, and as a result can be used as objective criterion for justification of need of holding forestry and landscape actions.
