Polyaspartic acid is a kind of biodegradable scale inhibitor,but its single use can not meet the practical application of water treatment.Therefore,the combination of polyaspartic acid and other water quality stabilizers has attracted considerable attention in this field.The re-search progress on the compound of polyaspartic acids and inorganic compounds,organic com-pounds,organic acids and polymers are reviewed,and the combination has a scale inhibition, corrosion inhibition,sterilization,chelating and other properties.Furthermore,the prospect in this field are discussed.%聚天冬氨酸是一类可生物降解的阻垢剂，但其单一使用不能满足水处理的实际应用，聚天冬氨酸与其他水质稳定剂的复配成为这一领域的研究热点。基于此综述了聚天冬氨酸与无机类，有机膦酸类和高分子化合物等复配的研究进展，复配后的水处理药剂同时具有阻垢、缓蚀、杀菌、螯合等性能，并对这一领域的研究进行了展望。
