species were introduced to the United Arab Emirates (UAE) region for desert greening. However, the species now pose a great threat to the native plant diversity. This study used high-resolution satellite imagery (1990-2019) to understand the history and current distribution of species and their impact on fresh groundwater. The results show that the invasion in the study area reached its maximum expansion rate in 2019 and covered an area of about 16 km compared to 0.2 km in 1990. The areas near Sharjah Airport, Umm Fannan, and Al Talla, located at a lower elevation of the sand dune area, are heavily invaded. groundwater requirement derived using evapotranspiration shows that groundwater consumption has changed drastically after 2010 and consumed about 22.22 million m of groundwater in 2019, which is about a 7372% increase in groundwater consumption from the year 1990 to 2019. The results can be useful for setting up a management plan for the sustainable use of this species in the UAE region in particular and other similar countries in the arid land regions that are suffering from freshwater depletion because of invasion.
一些物种被引入阿拉伯联合酋长国（阿联酋）地区用于沙漠绿化。然而，这些物种现在对当地植物多样性构成了巨大威胁。本研究使用高分辨率卫星图像（1990 - 2019年）来了解这些物种的历史和当前分布及其对新鲜地下水的影响。结果表明，研究区域内该物种的入侵在2019年达到最大扩张率，覆盖面积约为16平方千米，而1990年为0.2平方千米。位于沙丘地区较低海拔处的沙迦机场、乌姆法南和阿勒塔拉附近地区受到严重入侵。利用蒸散量得出的地下水需求量表明，2010年后地下水消耗量发生了巨大变化，2019年消耗了约2222万立方米的地下水，这是1990年至2019年地下水消耗量约7372%的增长。这些结果对于制定阿联酋地区特别是其他干旱土地地区因该物种入侵而面临淡水枯竭的类似国家该物种可持续利用的管理计划可能会有所帮助。
