摘　　要：钼是植物、动物和微生物必需的微量元素之一,同时也是一种重金属元素。以往对钼的研究主要关注钼缺乏对农作物产量与品质的影响及危害,对钼污染导致的生态风险及应对策略研究较少。本文在分析我国土壤钼污染现状及其生态风险的基础上,综述了钼污染对植物生长发育的影响、钼对植物的毒害阈值及其影响因子,以及植物对钼污染的耐性机制,并展望了未来土壤-植物系统钼污染的研究方向,以期为土壤钼污染的风险管控及修复提供参考。Molybdenum(Mo)is one of the essential trace minerals and an important strategic resource for plants,animals,and microorganisms.Previous research mainly focused on the effects of Mo deficiency on the yield and quality of crops,while the studies on ecological risks and curative measures have not been reported.In this study,the current position and ecological risk of soil Mo pollution in China were analyzed.The effects of Mo pollution on the growth and development of plants,the toxicity threshold in plants and its influencing factors,and the tolerance mechanisms of plants to Mo pollution were reviewed,and the prospects of Mo contamination in soilplant systems were proposed.The information is useful in providing guidance for risk control and remediation of soil Mo pollution.
