The restoration of areas invaded by non‐native plants is challenging as invasive plants may affect both biotic and abiotic components of ecosystems, leading to impacts that constrain recolonization by native species after invaders are eliminated. In such a scenario, restoration techniques as topsoil transposition might accelerate colonization by native species in forests. Hedychium coronarium J. Koenig (Zingiberaceae) is a Himalayan herbaceous rhizomatous plant recognized as invasive in several countries. This study aimed to experimentally evaluate the response of plant assemblages to topsoil transposition on a site invaded by H. coronarium after chemical control. Four treatments were applied: chemical control integrated with topsoil transposition, chemical control of H. coronarium alone, topsoil transposition alone, and no intervention (control). Plots were evaluated prior to the application of treatments and then monthly for 11 months after treatments. Parameters were measured for H. coronarium (number of ramets, ramet height, and cover) and other species (species richness, abundance, and cover). Plots treated with chemical control (regardless of topsoil transposition) were similar in terms of all parameters measured and species composition, with dominance of herbs and shrubs. Plots managed solely with topsoil transposition had lower species richness, abundance, and cover, but more diverse life‐forms, being equally rich in climbers, trees, and herbs. Chemical control was effective to control invasion by H. coronarium and increase species richness and abundance on the managed site. Topsoil transposition promoted colonization by species that might accelerate restoration.

整合管理技术以恢复在生物多样性热点中被硬皮花冠花科（Kingenaceae）（姜科）入侵的亚热带森林

由于外来入侵植物可能会影响生态系统的生物和非生物成分，因此恢复非本土植物入侵的区域具有挑战性，导致影响消除了入侵者后限制了本地物种的重新定殖。在这种情况下，表土换位等修复技术可能会加速森林中本地物种的定殖。Hedychium coronarium J. Koenig（姜科）是喜马拉雅草根茎植物，在一些国家被认为是入侵植物。这项研究旨在通过实验评估化学控制后植物组合对表土转位的反应，该土壤被冠状血吸虫入侵。进行了四种处理：化学控制与表土换位集成，化学控制单独使用冠状杆菌，单独使用表土，无需干预（对照）。在进行治疗之前先对地块进行评估，然后在治疗后的11个月中每月进行评估。测量冠状血吸虫（分株数，分株高度和覆盖率）和其他物种（物种丰富度，丰度和覆盖率）的参数。在所有测得的参数和物种组成方面，用化学控制处理的地块（无论表土如何换位）都相似，其中草药和灌木占优势。仅靠表层土壤换位处理的地块的物种丰富度，丰富度和覆盖率较低，但生命形式却更多样化，同样富含攀援植物，树木和草药。化学控制有效地控制了冠状杆菌的入侵并增加管理地点的物种丰富度和丰度。表土移位促进了可能加速恢复的物种的定殖。
