Effects of bio-invasion on the Yellow River basin ecosystem and its countermeasures.
A healthy ecosystem in the Yellow River basin is central to ecological protection and high-quality development along the Yellow River region. However, the rapid development in the economy and increase in human activity has resulted in a large number of invasive species being introduced into the Yellow River basin and occupying native species ecological niches. The outbreak and spread of invasive species pose a serious threat to native organisms and ecosystems in the Yellow River basin and can even seriously affect human health. Therefore, it is important 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 to put forward strategies for the protection of native species. Here, we review the bio-invasion characteristics, transmission approaches and mechanisms in the nine provinces of Yellow River basin, and the effects of bio-invasion on the biological resources and ecological system in the Yellow River basin. We then suggest measures and countermeasures to reduce current effects of bio-invasion, protect the Yellow River healthy ecosystems, and ensure high-quality development.
