摘要:

为提高植物修复技术对污染土壤的修复效率,根据当今植物修复技术在污染土壤修复中的应用现状及发展趋势,对近年来国内外植物修复技术的各种影响因素进行分析。首先从污染物的理化性质及其交互作用、土壤与气象因子、植物种类及其根际效应以及栽培措施等方面,系统论述影响土壤中重金属污染物及有机污染物植物修复效率的主要因素,阐述植物添加剂对植物修复效率的影响。最后指出植物修复今后研究的重点:营造促进植物生长发育的环境,针对影响植物修复效率的各个因素对植物修复技术进行改良及强化,并合理应用植物添加剂,提高植物修复效率。

Abstract:

Based on recent results of phytoremediation techniques applied in curbing environmental contamination, various factors influencing the efficiency of phytoremediation of contaminated soils were analyzed and summarized. First of all, three aspects of the main factors of phytoremediation efficiency of heavy metal pollutants and organic pollutants in soil were analyzed. That is, the physical and chemical properties of pollutants and their interaction effects, soil and climate conditions, and plant species, rhizosphere effects and cultivation measures. And then, the influence of additives on the phytoremediation efficiency was elaborated. Finally, issues for further research on phytoremediation of contaminated soil were discussed, including: providing good environment to promote plant growth and development, improving and strengthening the phytoremediation according to the factors that influence the efficiency of phytoremediation, and applying plant additives reasonably to improve the efficiency of phytoremediation.
