Industrial pollution remains a driving force to ecosystem alteration. Pollutants are released in the atmosphere interacting in turn with other components of earth system such as plant species. Despite the long-term exposition of vegetation cover to pollution is drastically devastating, less is known about the contribution of ecological indicators for its monitoring. The aims of this study are (i) to introduce the ecological indicators in assessing the cement dust impact on plant species and its biomonitoring and (ii) to screen new indicator species for phytoremediation studies. Floristic surveys were conducted in the cement plant closeness following quadrat method. Vegetation indicators such as total plant cover, perennial and annual species densities and diversity were assessed. Bioindicator species were identified using the bioaccumulation factor (BF) and translocation factor (TF). A decrease of perennial species richness and a decline of total vegetation cover by 7 times as well as a diversity decrease ranging from 2.99 to 2.31 were found pertinent indicators of land degradation in the industrial area. Annual species densities were significantly affected by cement pollution. Species like Lygeum spartum, Atractylis serratuloides and Gymnocarpos decander arise as indicators of heavy metals pollution. Pollution in the cement plant vicinity excluded sensitive species like Helianthemum kahiricum, Stipa tenassissima, Plantago coronopus. This study allowed the identification of indicator species of potential use in phytoremediation applications and emphasized the possibility of relaying on the vegetation indicators to assess the impact of cement pollution.

工业污染仍然是生态系统改变的驱动力。污染物释放到大气中，依次与地球系统的其他组成部分（例如植物物种）相互作用。尽管长期将植被覆盖暴露在污染中是灾难性的，但人们对生态指标对其监测的贡献知之甚少。这项研究的目的是（i）引入生态指标以评估水泥粉尘对植物物种及其生物监测的影响，以及（ii）筛选用于植物修复研究的新指标物种。按照方差法对水泥厂的紧密度进行了植物调查。评估了植被指标，例如总植物覆盖率，多年生和一年生物种密度和多样性。使用生物蓄积因子（BF）和易位因子（TF）识别生物指示剂种类。发现工业区土地退化的相关指标是多年生物种丰富度下降和总植被覆盖率下降了7倍，多样性下降了2.99至2.31。水泥污染严重影响了年度物种密度。像Lygeum spartum，Atractylis serratuloides和Gymnocarpos decander这样的物种成为重金属污染的指标。水泥厂附近的污染排除了敏感种，如向日葵（Helianthemum kahiricum），针茅（Stipa tenassissima），车前子（Plantago coronopus）。这项研究允许确定在植物修复应用中可能使用的指示剂种类，并强调了依靠植被指标评估水泥污染影响的可能性。
