The diversity of vascular plant species at two border railway stations, Chop in southwestern Ukraine and Čierna nad Tisou in southeastern Slovakia, was studied and compared. The Chop station flora consisted of 240 taxa, while Čierna nad Tisou had 309 taxa. 173 taxa were common to both stations, 67 taxa occurred only in Chop and 136 only in Čierna nad Tisou. Native species prevailed over alien at both stations; neophytes dominated over archaeophytes in Chop, whereas archaeophytes were dominant in Čierna nad Tisou. The floristic composition of the Chop and Čierna nad Tisou railway stations included species which were mostly hemicryptophytes and therophytes, with European and Asian origin, predominantly insect pollinated, reproducing by seeds, mostly competitors, urbanoneutral or moderately urbanophobic, and growing in habitats moderately influenced by human activity. The native species were predominantly urbanophobic hemicryptophytes while the alien species were mainly urbanophilic therophytes that were more thermophilous than the natives. The most abundant families at both stations were Asteraceae and Poaceae. The greater species diversity in Čierna nad Tisou and the differences in species composition between the stations probably arise from the size, structure and treatment of the station, the station surroundings, and the size of the associated city. Species Euphorbia davidii, Galeopsis angustifolia, Geranium purpureum, and Grindelia squarrosa are discussed as examples of ferroviatic species migration.

研究和比较了两个边境火车站（乌克兰西南部的Chop和斯洛伐克东南部的Čiernanad Tisou）的维管植物物种多样性。Chop站的植物群包括240个分类单元，而Čiernanad Tisou有309个分类单元。这两个站点共有173个分类单元，仅在Chop中出现67个分类单元，仅在Čiernanad Tisou中出现136个分类单元。在这两个站，当地物种战胜了外来物种。在Chop，新生物占主导地位，而在Čiernanad Tisou，古生物占主导地位。Chop和Čiernanad Tisou火车站的植物学组成包括以下种类：半隐生植物和附生植物，起源于欧洲和亚洲，主要是昆虫授粉，种子繁殖，主要是竞争者，城市单性或中等城市嗜性，并在受人类活动适度影响的栖息地中生长。本地物种主要是城市嗜热的半生植物，而外来物种主要是都市嗜热的植物，比本地人更具嗜热性。两个站中最丰富的科是菊科和禾本科。Čiernanad Tisou的物种多样性更大，而站点之间的物种组成差异也可能是由站点的大小，结构和处理方式，站点的环境以及相关城市的大小引起的。种类 Čiernanad Tisou的物种多样性更大，而站点之间的物种组成差异也可能是由站点的大小，结构和处理方式，站点的环境以及相关城市的大小引起的。种类 Čiernanad Tisou的物种多样性更大，而站点之间的物种组成差异也可能是由站点的大小，结构和处理方式，站点的环境以及相关城市的大小引起的。种类大戟刺，鼬瓣花属沙枣，天竺葵草，和Grindelia草如ferroviatic物种迁移的实例中讨论。
