摘　　要：本研究于2020至2021年在西喀尔巴阡山脉的山麓地区进行,研究了高山天南星(Arum alpinum)的物种数量和选定特征的空间-时间变异。调查分别在4个永久样地中进行(Patch Ⅰ、Ⅱ、Ⅲ、Ⅳ)。Patch Ⅰ和Patch Ⅲ位于以低矮植被为主的枫树-鹅耳枥林(Tilio cordatae-Carpinetum betuli)林地中,而Patch Ⅱ和Patch Ⅳ位于以阔叶物种为主的白杨(Populetum albae)河滩林中。调查结果表明,高山天南星最丰富种群出现在Patch Ⅰ,但Patch Ⅱ和Patch Ⅳ中也存在大量的营养体和繁殖个体。个体性状的时间变异性在Patch Ⅳ最低,其次是Patch Ⅰ和Patch Ⅱ,在Patch Ⅲ最高。所有种群中均发现叶柄长度与叶片尺寸以及有性茎长度与果序特征之间的关系显著呈正相关,这一发现证实了先前的研究。这些研究结果表明,高山天南星与特定的森林群落没有密切关联。充足的遮荫和湿润富养分的土壤对该物种有利,而干燥的土壤和过多的日照可能会限制其个体的开花与结果。Studies of selected habitat conditions,as well as spatiotemporal variability of the number and selected traits of individuals of the species Arum alpinum were carried out in 2020-2021 in the foothills of the Western Carpathians.The investigations were conducted in permanent patches located in the Golesz nature reserve(Patch Ⅰ),near the village of Markowce(Patch Ⅱ),in the Kozigarb nature reserve(Patch Ⅲ),and near the village of Żółków(Patch Ⅳ).Patches Ⅰ and Ⅲ were established in a Tilio cordatae-Carpinetum betuli oak-hornbeam forest with undergrowth dominated by low-growth vegetation with narrow leaves,whereas Patches Ⅱ and Ⅳ were established in a Populetum albae riparian forest with undergrowth dominated by broad-leaved species.The most abundant population of A.alpinum was noted in Patch I,but substantial numbers of both vegetative and reproductive individuals were also present in Patches Ⅱ and Ⅳ.The occurrence of temporal variability of individual traits increased from its lowest level in Patch Ⅳ,through Patches Ⅰ and Ⅱ,to its highest level in Patch Ⅲ.The significant positive correlation in all populations between length of petioles and blade dimensions,as well as between length of generative stems and infructescence traits confirmed previous findings.Moreover,we showed that A.alpinum was not closely affiliated with a specific forest community.Significant shading and moist nutrient-rich soils are suitable for this species,while dry soils and excessive insolation may limit the flowering and fruiting of individuals.
