摘　　要：火是森林和草原生态系统的重要干扰因素,火干扰后的土壤理化性质、土壤微生物群落等变化对森林和草原生态系统结构和功能的恢复具有重要影响。近年来,国内外学者对森林和草原火干扰开展了研究并取得一定成果。笔者综述了火干扰对森林和草原土壤的理化性质及微生物等方面的研究现状,并提出了今后可从加强构建火干扰模型、提高草原火干扰对土壤影响等方面提出了展望,以期为研究火干扰对森林和草原土壤影响的研究提供理论依据。Fire is an important disturbance factor in forest and grassland ecosystems.The changes of soil physical and chemical properties and soil microorganisms after fire disturbance have important impacts on the restoration of forest and grassland ecosystem structure and function.In recent years,domestic and foreign scholars had conducted research on forest and grassland fire interference and made some achievements.The authors summarized the current research status of fire disturbance on the physical and chemical properties and microorganism of forest and grassland soil,proposed the prospect of strengthening the construction of fire disturbance model as well as improving the impact of grassland fire disturbance on soil.In the nutshell,it would provide a theoretical basis for the study of the effects of fire disturbance on forest and grassland soil.
