摘　　要：生物炭是一类具有比表面积大、疏松多孔、含碳量极高的固体物质,近年来,作为一种新型的环境材料受到广泛的关注。然而,由于原料种类、制备工艺等诸多因素的影响,生物炭的应用对土壤生态系统的影响表现复杂多样。在此综述了不同原料制备的生物炭的理化特征,总结了生物炭对土壤生态系统中植物、土壤动物、土壤微生物生态的影响,最后针对生物炭的土壤生态效应研究提出展望,为生物炭正向调控土壤生态系统以及生物炭的合理应用提供参考。Biochar is a kind of solid material with large specific surface area,porosity and high carbon content.In recent years,as a new type of environmental material,biochar draws the attention of the public.However,due to the influence of various factors such as raw material types and preparation technology,the effects of biochar application on soil ecosystem are complex and diverse.In this paper,the physical and chemical characteristics of biochar prepared from different raw materials were summarized,and the effects of biochar on plants,animals and microorganisms in soil ecosystem were discussed.Finally,the prospect of the research on the soil ecological effect of biochar was put forward,so as to provide the reference for the positive regulation of soil ecosystem by biochar and the rational application of biochar.
