生物炭对污染土壤修复的研究进展

Research Progress of Remediation of Contaminated Soil With Biochar

土壤是生物圈的重要组成部分,是人类生存和发展的基础,同时也是保障国家粮食安全的最基本的生产材料。随着人类社会经济的发展和人类活动的高度密集,土壤污染程度越来越严重。土壤质量持续恶化,严重影响人类健康,因此开展针对污染土壤的修复工作刻不容缓。生物炭作为一种在土壤改良、生物能源生产、有机废物循环利用和温室气体减排等方面具有积极意义的物质,对于农业应用方面有重要意义,引起了国内外研究者的广泛关注,成为近年来的研究热点之一。

Soil is an important part of the biosphere,is the foundation of human survival and development,is also the most basic production material to ensure national food security.With the development of human society economy and highly intensive human activities,soil pollution is more and more serious,soil quality is deteriorating,which has serious impact on human health and life development.Therefore,the remediation of contaminated soil is urgent.Biochar as a substance with positive significance in soil improvement,bioenergy production,organic waste recycling and greenhouse gas emission reduction is of great significance in the agriculture,so it has attracted widespread attention of researchers at home and abroad,and has become one of the research hotspots in recent years.
