摘要: 隨著人們生活水平的提升、工業(yè)化進(jìn)程和城市化的不斷發(fā)展，土壤重金屬污染已成為當(dāng)今社會(huì)發(fā)展面臨的一個(gè)很嚴(yán)峻的環(huán)境問題，因此加強(qiáng)土壤重金屬污染的修復(fù)刻不容緩。近年來興起的植物修復(fù)技術(shù)相比于其它修復(fù)技術(shù)有著良好的發(fā)展前景，但植物修復(fù)效率一直是困擾該技術(shù)的難題。大量研究表明，水分管理會(huì)引起土壤理化性質(zhì)及重金屬形態(tài)的改變，同時(shí)改變植物體內(nèi)重金屬的含量和遷移。本文在前人的研究基礎(chǔ)上，綜述了水分管理對(duì)土壤物理、化學(xué)、生物學(xué)性質(zhì)以及植物本身的影響，分析了不同水分條件下植物的修復(fù)效率，提出了未來發(fā)展建議，為保證我國糧食安全和農(nóng)業(yè)綠色發(fā)展提供理論基礎(chǔ)和實(shí)踐依據(jù)。

Abstract: With the improvement of people’s living standards, the continuous development of industrialization and urbanization, soil heavy metal pollution has become a very serious environmental problem. It is urgent to strengthen the remediation of soil heavy metal pollution. In recent years, phytoremediation techniques have a promising future compared with other remediation techniques, but the efficiency of phytoremediation was a difficult problem. A large number of studies have shown that water management can change the physical and chemical properties of soils and the form of heavy metals, and affect the content and migration of heavy metals in plants. Based on previous studies, this paper reviewed the effects of water management on soil's physical, chemical and biological properties, as well as plants themselves, analyzed the remediation efficiency of plants under different water conditions, and the suggestions for future development were put forward, which will provide a theoretical and practical basis for ensuring food security and green agricultural development in China.
