Динамика горных лесов на охраняемой территории (заповедник «Столбы»)

Динамика горных лесов на охраняемой территории (заповедник «Столбы»)

Abstract

В Государственном природном заповеднике «Столбы» по материалам разных лет (1959, 1977, 2007 гг.) учета древостоев выявлено уменьшение площадей с преобладанием мягколиственных пород и лиственницы. Происходит расширение площади насаждений с участием пихты и сосны. За последние 50 лет не наблюдается заметных изменений площадей кедровых и еловых древостоев. Лиственные древостои отличаются быстрыми темпами накопления запаса, но пониженной продуктивностью по сравнению с хвойными. В хвойных формациях наблюдается переход одновозрастных в разновозрастные древостои, близкие к климаксовому состоянию. Кедрачи растут по типу одновозрастных, что связано, вероятно, с их недавним появлением на этой территории

Accounting stands (1959, 1977, 2007) revealed reduction of areas dominated by deciduous species and larch in the State Nature Reserve "Stolby". Area stands of fir and pine increased. Area stands of cedar and spruce didn’t change over the last 50 years. Deciduous stands differs rapid accumulation of stock, but they have productivity lower then conifers. There is a shift in even-aged stands to multiple-aged stands in coniferous formations. They are close to a climax state. Cedars grow on the type of the even-aged stands, because they appeared in the area recently
