Abstract

An inventory of alien and native species of vascular plants was taken along the Trans-Siberian Railway, from the settlement of Yerofey Pavlovich to Kundur-Khabarovskiy railway station, with the total length of 1043 km (11 % of the TSR) explored. The study encompassed sixteen railway stations located in two biomes, including Amur-Zeya Boreal Taiga with variants southern taiga and subtaiga, and Zeya-Bureya Nemoral Broadleaved Forests and Forest-Steppe ones. The highest similarity was displayed by south taiga and subtaiga variants of the Amur-Zeya Boreal Taiga biome, with Sørensen’s coefficient equaling to Ks = 46 % on embankment slopes and Ks = 45 % for rail bed, while a low measure of similarity was detected in the railway right of way (Ks = 24 %). The number of railway flora species displays a strong positive correlation with average annual temperature and average annual precipitation within the biome, and a strong negative correlation with the total number of vascular plants recorded within the biome, as well as with the biome area.

西伯利亚大铁路阿穆尔河段外来和原生植物区系及其与自然生物群落特征的关系

对西伯利亚大铁路沿线的外来和本地维管植物物种进行了盘点，从叶洛菲·帕夫洛维奇定居点到昆都尔-哈巴罗夫斯基火车站，全长1043公里(占总长度的11%)。该研究包括位于两个生物群落的16个火车站，包括阿穆尔-泽雅北方针叶林(南方针叶林和亚针叶林)和泽雅-布列雅阔叶林和森林-草原。南针叶林和亚针叶林的相似度最高，路基坡和铁路路基的Sørensen系数分别为46%和45%，铁路路权的相似度较低，为24%。铁路植物区系种类数与生物群系年平均气温和年平均降水呈显著正相关，与生物群系维管植物记录总数和生物群系面积呈显著负相关。

期刊介绍： Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
