生物质炭在红壤改良与重金属污染治理中的应用

The Application of Biochar on Soil Improvement and Heavy Metal Remediation in Red Soil

摘要: 红壤是我国重要的土壤类型之一，对我国农业发展和人民生活水平的提高有极其重要的意义。红壤呈现酸、黏、板、瘦等特征，且红壤区域水土流失问题和重金属污染问题也日趋严重。生物质炭作为近几年的研究热点，被认为是有效的土壤改良剂及土壤修复剂。综述了近十年生物质炭在红壤上的研究进展，并探讨了生物质炭对于红壤改良和重金属污染治理的作用。生物质炭在红壤上的应用具有巨大的潜力和积极的作用，但在大规模应用之前需要做长期的研究，并警惕其潜在的生态风险。

Abstract: Red soil is one of the most important soil types in China, which plays an important role in the de-velopment of agriculture and the improvement of people’s living standards. But red soil is charac-terized by acidity, stickiness, slab and thinness, while soil erosion and heavy metal pollution are also serious in red soil region. Biochar, as a research hotspot in recent years, is considered as an effective soil amendment and soil remediation agent. The research progress of biochar in red soil in recent ten years was reviewed, and the effects of biochar on red soil improvement and heavy mental remediation were discussed. The application of biochar in red soil has great potential and positive effect, but long-term research and ecological risk should be seriously considered before large-scale application.
