摘要: 生物质炭作为一种优质的土壤改良剂,由于其实现了资源的可循环利用且在农业及生态领域中有着巨大的应用价值和现实意义,因而近年来受到国内外学者的普遍关注。笔者综述了生物质炭在土壤重金属污染方面的修复作用,并从生物质炭对土壤团聚体微域环境的阳离子交换量、养分及微生物等方面的改善及影响入手,探索了生物质炭对土壤重金属污染的修复机制,研究结果表明生物质炭对土壤重金属形态及生物有效性有显著的固定及改善作用。旨在为该领域未来的研究提出展望和建议,以期为生物质炭的发展动向提供参考。

Abstract: As a kind of high quality soil conditioner, biochar made the resources recycled and realized. It has huge application value and practical significance in the field of agriculture and ecology, thus universal attention by scholars both at home and abroad has focused on biochar in recent years. This paper reviewed the biochar effects on the soil heavy metal pollution repair, and from the effect of biochar on the improvement of soil aggregate micro domain environment cation exchange capacity, nutrients and organic matter, explored the effects of biochar to soil heavy metal pollution repair mechanism. The results showed that the biochar played a significant role in fixing and improving the form of soil heavy metal and the biological effectiveness. Suggestions and prospect for future research in this field were proposed in this paper, so as to provide a reference for biomass charcoal development.
