Abstract

Postfire (2010) formations of Pinus sylvestris and Betula pendula (51°48′30.1′′ N, 39°23′58.4′′ E) have been studied. This article presents the results of these studies for 2015–2016. Descriptions of these formations have been carried out since 2012. Methods for the analysis of the structures of plant communities are of especial importance, both for an understanding of their annual ecological state and the identification of plant resistance to the pyrogenic factor. Information on the beginning of restoration of the phytocenosis structure and flora, on the change of dominants in vegetation layers, an increase of the projective cover, and the formation of forest phytocenosis is given on example of common and pyrogenic associations of these formations. A decrease in weed species abundance and their projective cover was noted. The current list of flora includes 84 species from 75 genera, 33 families, and 2 divisions: Pinophyta and Magnoliophyta. The dominant families are Poaceae with 12 species (14.1%), Asteraceae with eight species (9.4%), and Fabaceae with six species (7%). The small list of dominant families with a small number of species confirms the large disturbance of flora by the pyrogenic factor. The dominance of rhizome plants (42 species, 44.6%) and a small number of cespitose plants (4 species, 4.8%) indicates the advantage of the forest phytocenotic group. The presence of a xerophytic group (15 species, 17.9%) indicates increased insolation and a decreased moisture content in these postfire formations. Eight geoelements and 14 types of habitats have been identified. The European one predominates, with 53 species (63.1%) and 12 types of habitats.

摘要

樟子松桦桦的后火(2010)形成已经研究了(51°48'30.1''N,39°23'58.4''E)。本文介绍了2015-2016年这些研究的结果。自2012年以来已对这些形成进行了描述。分析植物群落结构的方法特别重要,既可用于了解其年度生态状况,又可用于鉴定植物对热原性的抗性。关于植物群落结构和植物区系恢复的开始,植被层优势成分的变化,射影覆盖率的增加以及森林植物群落形成的信息,都以这些形态的常见和热解联系为例。注意到杂草物种丰度及其投射覆盖率降低。目前的植物群清单包括来自75个属,33个科的84种 和2个分区:斑癣菌和Magnoliophyta。优势科是禾本科(Poaceae)有12种(14.1%),菊科(Asteraceae)有8种(9.4%)和豆科(Fabaceae)有6种(7%)。少数物种的少数优势家族名单证实了热原性因素对植物区系的干扰很大。根茎类植物(42种,占44.6%)和少量的鞘翅类植物(4种,占4.8%)的优势表明了森林植物诱生组的优势。旱生植物群(15种,17.9%)的存在表明这些后火地层的日射增加和水分含量降低。已经确定了8个地理元素和14种栖息地类型。欧洲人占主导地位,有53种(63.1%)和12种栖息地。1%),菊科(Aceaceae)有8种(9.4%)和豆科(Fabaceae)有6种(7%)。少数物种的少数优势家族名单证实了热原性因素对植物区系的干扰很大。根茎类植物(42种,占44.6%)和少量的鞘翅类植物(4种,占4.8%)的优势表明了森林植物诱生组的优势。旱生植物群(15种,17.9%)的存在表明这些后火地层的日射增加和水分含量降低。已经确定了8个地理元素和14种栖息地类型。欧洲人占主导地位,有53种(63.1%)和12种栖息地。1%),菊科(Aceaceae)有8种(9.4%)和豆科(Fabaceae)有6种(7%)。少数物种的少数优势家族名单证实了热原性因素对植物区系的干扰很大。根茎类植物(42种,占44.6%)和少量的鞘翅类植物(4种,占4.8%)的优势表明了森林植物诱生组的优势。旱生植物群(15种,17.9%)的存在表明这些后火地层的日射增加和水分含量降低。已经确定了8个地理元素和14种栖息地类型。欧洲人占主导地位,有53种(63.1%)和12种栖息地。少数物种的少数优势家族名单证实了热原性因素对植物区系的干扰很大。根茎类植物(42种,占44.6%)和少量的鞘翅类植物(4种,占4.8%)的优势表明了森林植物诱生组的优势。旱生植物群(15种,17.9%)的存在表明这些后火地层的日射增加和水分含量降低。已经确定了8个地理元素和14种栖息地类型。欧洲人占主导地位,有53种(63.1%)和12种栖息地。少数物种的少数优势家族名单证实了热原性因素对植物区系的干扰很大。根茎类植物(42种,占44.6%)和少量的鞘翅类植物(4种,占4.8%)的优势表明了森林植物诱生组的优势。旱生植物群(15种,17.9%)的存在表明这些后火地层的日射增加和水分含量降低。已经确定了8个地理元素和14种栖息地类型。欧洲人占主导地位,有53种(63.1%)和12种栖息地。9%)表示这些后火地层中的日射增加和水分含量降低。已经确定了8个地理元素和14种栖息地类型。欧洲人占主导地位,有53种(63.1%)和12种栖息地。9%)表示这些后火地层中的日射增加和水分含量降低。已经确定了8个地理元素和14种栖息地类型。欧洲人占主导地位,有53种(63.1%)和12种栖息地。
