污染土壤修复技术预测

Forecast of remediation technology of contaminated soil

土壤污染已成为世界性环境问题,我国土壤污染现状更为严峻。污染土壤修复技术已成为全球科技的研究重点。本研究基于该领域国内外的相关研究论文与专利,采用文献计量学的统计方法,结合国内外相关项目、计划和法规等信息,对比分析了国内外论文/专利发文量阶段变化、技术研究的首篇报道年、专利景观图等。研究结果表明,我国污染土壤修复技术研发起步较晚,与发达国家总体水平存在10~15年的差距,在产业化领域更为突出。提出了在兼顾系统集成与技术原创的条件下,我国污染土壤修复的重点研发技术,为我国土壤修复技术的发展布局与政策制定提供决策依据。

Soil pollution has become a global environmental problem, and it＇ s more serious in China. Remedia- tion technology of contaminated soil was the focus of research in the world. Based on the research papers and pa- tents in the related field of domestic and international, this study used the literature metrology and analyzed the quantity of research papers and patents, publication year and patents landscape map. The results demonstrated the research on contaminated soil remediation technology started relatively late in China. There are 10-15 years gap of contaminated soil remediation technology between domestic and foreign, especially in industrial field. Within system integration and original technology, the key technologies for contaminated soils remediation were proposed in China. The researches could provide the decision-making basis for soil pollution remediation technol- ogy＇s industrial and policy.
