| 摘 要： | 文章根据2019年、2020年漳江口红树林保护区内互花米草、沉积物、潮间带底栖生物的调查结果，结合历史遥感影像资料分析互花米草的入侵过程。结果表明：漳江口红树林保护区互花米草高潮区株高略低于同潮区红树植物，亦低于中潮区互花米草株高，更倾向于向光滩扩张；研究区域互花米草区沉积物中总氮、硫化物和有机碳含量高于光滩，全盐含量低于光滩；根据研究区域的遥感影像分析，2011—2019年漳江口互花米草保持较高的速率扩张，2020年互花米草扩张进入稳定期；根据丰度生物量比较法，2020年互花米草区的潮间带底栖生物群落结构较2019年稳定。在研究互花米草入侵对滨海湿地的影响时，除了考虑调查方法、时空因素和样地互花米草入侵时间的长短外，还应考虑互花米草入侵的不同扩张时期。

| Abstract: | Based on the survey results of Spartina alterniflora, sediments, and intertidal benthic organisms in Zhangjiang Estuary Mangrove Reserve in 2019 and 2020, and combined with historical remote sensing image data, this paper analyzed the invasion process of S. alterniflora. The results showed that: The plant height of S. alterniflora in the high tide area of Zhangjiang Estuary Mangrove Reserve was slightly lower than that of mangroves in the same tidal area, and also lower than that of S. alterniflora in the middle tidal area, and it was more inclined to expand to the beach. The contents of total nitrogen, sulfide and organic carbon in the sediments of S. alterniflora in the study area were higher than those of the sand, and the content of total salt was lower than that of the sand. According to the analysis of remote sensing images in the study area, S. alterniflora maintained a high rate of expansion in Zhangjiang Estuary Mangrove Reserve from 2011 to 2019, and the expansion of S. alterniflora entered a stable period in 2020. According to the abundance biomass comparison method, the intertidal benthic community structure in the S. alterniflora area in 2020 was more stable than that in 2019. This study believes that when studying the impact of S. alterniflora invasion on coastal wetlands, in addition to considering the survey method, temporal and spatial factors and the length of the invasion time of S. alterniflora, the different expansion periods of S. alterniflora invasion should also be considered. |
