摘要

俄罗斯黑海南部地区的路边植物群落具有较高的外来化程度和较低的入侵性。在这些群落中,由于入侵物种的丰富度和竞争力,外来化进程迅速推进。共优势物种(来自入侵物种)的总投影覆盖也很重要:该参数值的增加降低了外来化和入侵性的水平。在黑海沿岸,Mzymta河和Shakhe河之间,即中湿润的亚热带气候条件下,路边植物群落密度最高,入侵物种竞争相对更强。从海岸到山区,入侵物种群落主要分布在平坦的河谷地带(地形崎岖度指数,发现入侵物种群落的概率超过50%)。

Factors of Adventivization of Roadside Plant Communities in the South of the Russian Black Sea Region
Roadside plant communities in the south of the Russian Black Sea region are characterized by relatively high adventivization and low invasibility. In these communities, the adventivization has been rapidly progressing due to the high abundance and competitiveness of invasive species in the region. The total projective cover of codominant species (from invasive species) is also important: an increase in the value of this parameter reduces the levels of adventivization and invasibility. On the Black Sea coast, the highest concentration of roadside plant communities with relatively more competitive invasive species is observed between the Mzymta and Shakhe Rivers, i.e., under the conditions of moderately humid subtropical climate. From the coast to the mountains, the communities with invasive species occur along the flat river valleys (Terrain Ruggedness Index with the probability of finding these communities exceeds 50%).
