我国典型植物修复材料研究及毛竹修复应用可行性分析

The Research of Typical Materials for Phytoremedication and the Application Feasibility of Phyllostachys heterocycla cv. pubescens

植物修复技术是一种绿色、经济、环保的重金属污染土壤修复技术,针对不同重金属污染土壤类型筛选植物修复材料,是目前土壤修复领域研究的热点之一。通过查阅文献梳理分析了我国典型修复植物的修复特征,从超积累植物、速生乔木、农作物三方面进行对比,探讨其优劣性;进而,结合毛竹的野外耐性、生长特性、使用范围三个方面的特质,探讨了毛竹作为土壤重金属污染植物修复材料的可行性;最后,通过文献分析的手段集中考察了我国今年对毛竹的研究热点,从而提出了毛竹作为修复材料的研究前景与方向,希望能够为重金属污染土壤植物修复技术提供新的技术手段和研究思路。

Phytoremediation is a green,economic and eco-environmental way to remediate the heavy metal contaminated soil,and the selection of candidate species is one of the research hot points. The typical materials for phytoremedication,including hyperaccumulators,fast-growing trees and crops,were analysed,and their advantages and disadvantages were compared. The heavy metal tolerance in the field,growth characteristics and utilization range of Phyllostachys heterocycla cv. pubescens were reviewed to explore its the feasibility to be a candidate of phytoremediation species. Based on the former researches,some study prospects and directions were proposed.
