城市土壤重金属研究进展

基于文献计量法探究城市土壤重金属研究的热点、修复技术与关键问题。城市土壤重金属污染是能有效反映城市环境污染状况的重要指标之一，城市土壤重金属生态地球化学、环境风险和污染修复是目前研究的热点和焦点。城市土壤与重金属微界面过程及机制、城市土壤重金属生物有效性及其健康风险以及城市土壤重金属复合污染效应、作用机理及其污染控制是目前城市土壤重金属研究有待解决的关键科学问题。城市土壤重金属研究仍然是今后环境科学研究的热点方向，而我国西部地区的研究有待加强。

Review of heavy metals in urban soils

Relevant literatures were reviewed .To explore the hotspots ,remediation technology and key problems of heavy metals in urban soils .Heavy metal contamination of urban soils can effectively reflect the status of urban environment quality .The ecological geochemistry ,environmental risks and remediation of heavy metals in soil are the hotspots and focus of current research .The interaction mechanism of heavy metals in urban soils at the micro in‐terface ,the bioavailability and health risks and compound pollution effect of heavy metals ,and pollution control are key problems in researches on urban soils .The study of heavy metals in urban soils is still a hot topic in the future , and the research of heavy metals in the western area of China needs to be strengthened .
