摘要
在以往20余年系统开展环境绿色修复基础研究与应用实践基础上,进行了成果总结与理论阐述。在补充、完善超积累/修复植物筛选评判标准的基础上,通过大量实践提出了“未污染区也存在超积累/修复植物”的新认识,构建了未污染区与污染区相互印证的超积累/修复植物筛选的新方法并得到验证;在阐明超积累/修复植物与环境介质的交互作用关系基础上,进一步探讨了超积累/修复植物形成的环境介质与植物交互作用机制以及环境修复的生态格局优化与综合强化的理论。这一进展将为今后该领域研究的深入开展和广泛实践打下理论基础,指明发展方向。
Result summaries and theoretical sublimation were made on the basis of researches,applications and practices in the field of environmental green remediation in the past two decades.At first,the new insight of"hyper accumulative or remediation plants also occur in non polluted areas"was put forward through a large number of practices,and a new meth od of mutual corroboration for screening out hyperaccumulators or remediation plants between clean areas and polluted areas was constructed and verified,on the basis of having supplemented and perfected the criteria for identifying and deter mining hyperaccumulators or remediation plants.Moreover,the theory of interaction between plants and environmental media based on the formation and growth of hyperaccumulators or remediation plants and the mechanisms of eco pattern op timization and comprehensive strengthening of environmental remediation are further proposed,on the basis of having clari fied the interaction relationship between hyperaccumulation/remediation plants and soil.This progress has undoubtedly laid a theoretical foundation for further development and extensive practice in this field in the future,and pointed out the direc tion of future development.
