Abstract: Invasive plants are foreign species that establish, reproduce, and spread outside their historical and current natural distribution ranges, causing significant adverse effects on local ecosystems, landscapes, and socioeconomic conditions. These invasive plant species alter ecosystem services through various mechanisms, posing an increasingly serious threat to global environmental health and ecological security. Soil provides the fundamental space for plant survival, and therefore understanding the impact of invasive plants on soil is crucial for comprehending their colonization, reproduction, and spread. Based on a comprehensive analysis of domestic and international literature, this paper systematically reviews recent research on the effects of invasive plants on soil properties, including physical and chemical characteristics, enzyme activity, and soil microorganisms. This paper explores the interactions between invasive plants and soil, summarizes the changes in soil characteristics following plant invasion, and discusses how invasive plants affect soil properties. Additionally, it provides an outlook on future research directions in this field, aiming to uncover the multifaceted impacts of invasive plants on soil, reveal the mechanisms of invasion, and offer scientific evidence for the effective prevention and control of invasive plants.
