目的：回顾近年来欧洲乡村景观中人类媒介扩散（HMD）的研究进展，并探讨HMD对草原保护的潜在积极作用，与其通常与入侵物种的传播有关。方法：进行了文献检索，以确定HMD载体在农村景观的讨论有关扩散潜力的过去和现在，对管理的影响，结果：放牧动物是重要的繁殖体传播者，但牲畜通过景观的运动减少也意味着以这种方式传播的种子减少。其他非标准的人类传播媒介，如衣服和机动车辆也可以运输许多物种的种子，HMD媒介通常运输种子与各种传播specialisations.Recommendations：应该有一个更大的移动放牧动物在整个景观，无论是在更大的放牧区或现有的草地之间。如果这是不可能的，其他的，更直接的传播繁殖体从物种丰富的社区到目标网站应考虑。应考虑非标准HMD载体对生物多样性作出积极贡献的潜力，但如果我们要充分了解它们在分散景观中植物物种扩散中的作用，对所有类型的HMD载体进行更多研究是重要的。
Objective: To review the recent research into human-mediated dispersal (HMD) in the European rural landscape, and explore the potential positive aspect of HMD for grassland conservation, in contrast to it's common association with the spread of invasive species.Methods: A literature search was undertaken to identify HMD vectors in the rural landscape for discussion regarding dispersal potential past and present, implications for management, and the identification of future research needs.Results: Grazing animals are important propagule dispersers, but the reduced movement of livestock through the landscape has also meant a reduction in seeds dispersed in this way. Other, non-standard human-mediated dispersal vectors such as clothing and motor vehicles can also transport seeds of many species, and HMD vectors often transport seeds with a variety of dispersal specialisations.Recommendations: There should be a greater movement of grazing animals throughout the landscape, either within larger grazing areas or between existing grasslands. Where this is not possible, other, more directed dispersal of propagules from species-rich communities to target sites should be considered. The potential of non-standard HMD vectors to make a positive contribution to biodiversity should be considered, but more research into all types of HMD vectors is important if we are to fully understand their role in the dispersal of plant species in fragmented landscapes.
