中文摘要：
植物修复是解决污染土壤问题的有效途径之一,而已报道的超积累植物的种类非常有限.如果能从物种繁多的花卉植物中筛选出修复植物,不但能够弥补这一不足,而且还能在美化环境的同时,产生一定的经济效益.从植物修复的重要性和修复植物的筛选出发,概括了修复植物的判断标准及基本特征.通过描述花卉植物资源及其在环境保护中的作用,列举花卉植物与其它植物相比的优势,分析花卉植物的耐性、积累性和修复类型,探讨花卉植物应用于污染土壤修复实践的可行性.从花卉中筛选超积累植物,将为污染土壤的修复工作提供的生物材料.
英文摘要：
Phytoremediation is one of the effective ways in resolving problems of contaminated soils, but limited hyperaccumulation plant species were reported and documented. This shortage could be offset if remediation plants can be screened out from various ornamental plants. In addition, such doing can beautify the environment while bring some economic effects. Starting from the importance of phytoremediation, this paper generalized the characters and standards of remediation plants. Through describing the resources of ornamental plants and their functions on environmental protec- tion, particularizing their superiorities to other plants, and analyzing their endurance, accumulation traits and remediation types, the feasibility of applying ornamental plants in the practices of contam- inated soil remediation was discussed. To screening out hyperaccumulators from ornamental plants would be an entirely new research area in the remediation of contaminated soils.
