摘　　要：铝是地壳中含量最丰富的金属元素,一般以无毒的固定态形式存在。随着土壤酸化加剧,铝毒害逐渐成为影响世界各地酸性土壤中作物生长的主要限制因素。本文聚焦于酸性土壤中各形态铝,围绕土壤中铝的来源和分类、各形态铝转化及酸性土壤中铝对植物的影响展开介绍,并展望了未来相关研究的发展方向,包括统一铝形态分类体系,统一铝毒害评价指标,规范各形态铝分离与检测方法,进一步建立酸性土壤铝毒害评价体系,最终推动国家农用地、建设用地等土壤铝污染风险管控标准的制定,以期为酸性土壤铝毒害带来的农业、生态、社会问题的解决提供依据。Aluminum is the most abundant metallic element in the earth′s crust and generally exists in the nontoxic stationary form.With the increase of soil acidification,aluminum toxicity is gradually becoming a major limiting factor affecting crop growth in acidic soil around the world.This paper focused on each form of aluminum in acidic soil,introduced the sources and classification of aluminum in soil,the transformation of each form of aluminum and the effects of aluminum on plants in acidic soil,and prospected the future development direction of related research,including unifying the classification system of aluminum forms,unifying the evaluation index of aluminum toxicity,standardizing the separation and detection methods of each form of aluminum,further establishing the evaluation system of aluminum toxicity in acidic soil,and eventually promoting the formulation of risk control standards for soil aluminum pollution in agricultural land and construction land,so as to provide a basis for solving agricultural,ecological and social problems caused by aluminum toxicity in acidic soil.
