摘　　要：互花米草作为外来入侵植物,在黄河三角洲地区迅速扩散,加速土壤盐渍化,威胁本地物种,破坏了生态系统健康。本研究通过遥感卫星图片分析技术,分析了黄河三角洲地区互花米草入侵足迹,发现互花米草完成定殖后(2004年前),迅速占领入侵生境并快速扩散(2004—2014)。尽管最近10 a人为抑制了互花米草的入侵速度,减少了入侵面积(2014—2024),但其仍具有卷土重来、二次入侵的可能性。因此,研究进一步对互花米草入侵不同阶段的假说进行了分类梳理,对比不同防治措施,考虑到互花米草入侵时对根际微生物的影响,提出可以从植物-土壤反馈机制入手研究互花米草的防治,提高对黄河三角洲互花米草入侵的微生物学机制的认识,科学探索互花米草微生物学防治的前景。研究旨在为未来互花米草入侵提供新的防治思路。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.
