Abstract
Global changes have altered the distribution pattern of the plant communities, including invasive species. Anthropogenic contamination may reduce native plant resistance to the invasive species. Thus, the focus of the current review is on the contaminant biogeochemical behavior among native plants, invasive species and the soil within the plant-soil ecosystem to improve our understanding of the interactions between invasive plants and environmental stressors. Our studies together with synthesis of the literature showed that a) the impacts of invasive species on environmental stress were heterogeneous, b) the size of the impact was variable, and c) the influence types were multidirectional even within the same impact type. However, invasive plants showed self-protective mechanisms when exposed to heavy metals (HMs) and provided either positive or negative influence on the bioavailability and toxicity of HMs. On the other hand, HMs may favor plant invasion due to the widespread higher tolerance of invasive plants to HMS together with the “escape behavior” of native plants when exposed to toxic HM pollution. However, there has been no consensus on whether elemental compositions of invasive plants are different from the natives in the polluted regions. A quantitative research comparing plant, litter and soil contaminant contents between native plants and the invaders in a global context is an indispensable research focus in the future.

入侵植物与重金属胁迫之间的相互作用:综述

摘要
全球变化改变了植物群落的分布格局,包括入侵物种。人为污染可能会降低本地植物对入侵物种的抵抗力。因此,本综述的重点是植物-土壤生态系统内本地植物、入侵物种和土壤之间的污染物生物地球化学行为,以提高我们对入侵植物与环境压力源之间相互作用的理解。我们的研究与文献综合表明 a) 入侵物种对环境压力的影响是异质的,b) 影响的大小是可变的,c) 即使在相同的影响类型内,影响类型也是多向的。然而,入侵植物在暴露于重金属(HMs)时表现出自我保护机制,并对重金属的生物利用度和毒性产生积极或消极的影响。另一方面,由于入侵植物对 HMS 的广泛耐受性以及本地植物在暴露于有毒 HM 污染时的“逃逸行为”,HMs 可能有利于植物入侵。然而,对于入侵植物的元素组成是否与污染地区的本地植物不同,尚未达成共识。在全球范围内比较本地植物和入侵者之间的植物、凋落物和土壤污染物含量的定量研究是未来不可或缺的研究重点。由于入侵植物对 HMS 的普遍较高耐受性以及本地植物在暴露于有毒 HM 污染时的“逃逸行为”,HMs 可能有利于植物入侵。然而,对于入侵植物的元素组成是否与污染地区的本地植物不同,尚未达成共识。在全球范围内比较本地植物和入侵者之间的植物、凋落物和土壤污染物含量的定量研究是未来不可或缺的研究重点。由于入侵植物对 HMS 的普遍较高耐受性以及本地植物在暴露于有毒 HM 污染时的“逃逸行为”,HMs 可能有利于植物入侵。然而,对于入侵植物的元素组成是否与污染地区的本地植物不同,尚未达成共识。在全球范围内比较本地植物和入侵者之间的植物、凋落物和土壤污染物含量的定量研究是未来不可或缺的研究重点。
