Abstract: A healthy ecosystem in the Yellow River basin is the core of ecological protection and high-quality development along the Yellow River region. With the rapid development of economy and the intensification of human activities, however, a large number of alien species have been introduced into and occupied the ecological niche of the Yellow River basin. The outbreaks and spreads of alien species poses a serious threat to native organisms and ecosystems in the Yellow River basin and even seriously affect human health. Therefore, it is of great significance for the ecological protection and high-quality development of the Yellow River basin to study the invasion of alien species in the Yellow River basin and put forward protection strategies. In this study we reviewed the bio-invasion characteristics, transmission approaches and mechanism in the nine provinces of Yellow River basin, and effects of bio-invasion on biological resources and the ecological system in the Yellow River basin. We then put forward the technical measures and countermeasures to reduce the adverse effects of bio-invasion and protect the Yellow River healthy ecosystems and high-quality development.

Key words: Yellow River basin, nine provinces and regions along the Yellow River, biological invasion, ecosystem, biological diversity
