Abstract:

Spartina alterniflora, as an alien invasive plant, has spread rapidly in the Yellow River Delta region, threatened native species, and damaged ecosystem health. This paper analyzes the invasion footprint of Spartina alterniflora in the Yellow River Delta by using remote sensing satellite image analysis techniques. It was found that after Spartina alterniflora completed colonization (before 2004), it quickly occupied the invaded habitat and rapidly spread (2004—2014). Although human intervention had suppressed the invasion speed of Spartina alterniflora and reduced the invasion area in the past decade (2014—2024), it still had the potential to make a comeback and reinvade. Therefore, we further classify and summarize the hypotheses of different stages of Spartina alterniflora invasion, compare various control measures, the prospect of scientific exploration of microbiological control of Spartina alterniflora in the future is proposed. The aim of this study is to provide a new way to prevent and control Spartina alterniflora invasion in the future.

Key words: Spartina alterniflora, Yellow River Delta, invasion mechanisms, invasion trajectory, control strategies
