景观植物修复对废旧铁路附近重金属过滤作用分析
|
摘要
在城市实现工业转型后,对废弃铁路附近土壤重金属污染区域进行景观植物修复,实现重金属过滤成为一个亟待解决的问题。本文以重金属污染的废旧铁路附近土壤需修复作为研究对象,分析研究该地区的土壤性质。其次,检测该地区土壤的重金属污染情况,有针对性地对该重金属污染地区进行植物修复重建,实验分析研究所选超富集植物对该地区的重金属元素的过滤作用。测试结果表明:超富集植物植物修复重建可以有效对生态敏感环境的重金属过滤,有效改善修复废旧铁路附近生态环境。
After the industrial transformation of the city, it has become an urgent problem to carry out landscape phytoremediation and heavy metal filtration in the soil polluted by abandoned railways. In this paper, the soil near the waste railway polluted by heavy metals needs to be repaired as the research object, and the soil properties in this area are analyzed and studied. Secondly, the heavy metal contamination of the soil in this area was detected, and the phytoremediation and reconstruction of the heavy metal contaminated area were carried out. The filtering effect of the selected super-enriched plants on the heavy metal elements in this area was analyzed by experiments. The results show that the phytoremediation and reconstruction of super-enriched plants can effectively filter heavy metals in ecologically sensitive environment and improve the ecological environment near the waste railway in Nanchang.
