An overgrowth of invasive floating macrophytes can occur in shallow eutrophic lakes as a result of significant anthropogenic pressures. This necessitates appropriate monitoring, followed by informed management, control and mitigation actions. In this study, we explored the long-term dynamics of macrophyte stands in a fluvial-wetland system and the influence of mechanical removal alongside environmental drivers. The Landsat imagery archive was used to analyze the areal coverage and canopy density of both autochthonous and allochthonous macrophytes in the Mantua lakes system (Northern Italy). Satellite derived data showed a substantial increase in the extent of the alien Nelumbo nucifera, and Ludwigia hexapetala, and the native Trapa natans over a timescale of decades, possibly caused by the temporary absence of macrophyte removal and altered hydrology. According to spectral proxies, N. nucifera recorded consistently the highest density in the system. T. natans density was found to respond to the maximum summer temperature and Eastern Atlantic climatic index, reflecting the role of regional climatic controls. This approach may be transferred to inland waters from regional to global scale exploiting satellite archives to obtain a time series on changing species dynamics essential for the conservation and management of aquatic habitats.

由于巨大的人为压力，侵入性漂浮大型植物可能会在富营养浅的湖泊中过度生长。这就需要进行适当的监视，然后进行明智的管理，控制和缓解措施。在这项研究中，我们探讨了河流-湿地系统中大型植物群落的长期动态以及机械驱除以及环境驱动因素的影响。Landsat影像档案库用于分析Mantua湖系统（意大利北部）中本地和外生大型植物的面积覆盖率和冠层密度。卫星得出的数据显示，外星人莲，和路德维希六瓣锦葵以及本土的pa蝶的范围大大增加。在几十年的时间范围内，可能是由于暂时缺乏大型植物的去除和水文状况的改变所致。根据光谱代理，N。nucifera始终记录系统中的最高密度。发现纳豆的密度对夏季的最高温度和东大西洋的气候指数有反应，反映了区域气候控制的作用。该方法可利用卫星档案库从区域到全球范围转移到内陆水域，以获得有关改变物种动态的时间序列，这对于保护和管理水生生境至关重要。
