is a perennial herb native to the American Atlantic coast and is the dominant plant in coastal intertidal wetlands. Since its introduction to China in 1979, it has quickly spread along the coast and has caused various hazards. To control the further spread of in China, we first reconstructed the history of the spread of in its invasion and origin countries. We found that spreads from the central coast to both sides of the coast in China, while it spreads from the west coast to the east coast in America. Furthermore, by comparing 19 environmental variables of in its invasion and origin countries, it was found that is more and more adaptable to the high temperature and dry environment in the invasion country. Finally, we predicted the suitable areas for this species in China and America using the maximum entropy (MaxEnt) model and ArcGIS. Overall, through analysis on the dynamic and trend of environmental characteristics during the invasion of and predicting its suitable area in the invasion area, it guides preventing its reintroduction and preventing its further spread of the species has been found. It has reference significance for studying other similar alien plants and essential enlightening relevance to its invasion and spread in similar areas.
是一种原产于美国大西洋沿岸的多年生草本植物，是沿海潮间带湿地的优势植物。自1979年引入中国以来，它已迅速在沿海地区蔓延并造成了各种危害。为了控制在中国的进一步扩散，我们首先重建了其在入侵和原产国的传播历史。我们发现，在中国从海岸中部向两侧扩散，而在美国从西海岸向东海岸扩散。此外，通过比较其在入侵和原产国的19个环境变量，发现越来越适应入侵国的高温和干燥环境。最后，我们使用最大熵（MaxEnt）模型和ArcGIS预测了该物种在中国和美国的适宜区域。总体而言，通过对入侵过程中环境特征的动态和趋势进行分析，并预测其在入侵区域的适宜区域，为防止其再次引入和防止该物种进一步扩散提供了指导。这对于研究其他类似外来植物具有参考意义，对于其在类似地区的入侵和扩散具有重要的启示作用。
