Abstract: As an important ecological factor,fire is closely related to our life. Grassland fire has been studied both at home and abroad. This paper discussed the research achievements of grassland fire,and deeply explored from the influence factors,ecological effects,space-time distribution pattern,grassland fire management,remote sensing monitoring,early warning and risk assessment. On the one hand,it provided strong scientific basis for relevant decision-making departments,thus ensured the standardized management of grassland fire and the balance of grassland ecological environment. On the other hand,it provided a basis for the study on the occurrence and development of grassland fire and their impact on relevant regions and even future global climate change,and then contributed to the research on current global climate change. Due to the limitations in the field of study and the discontinuity problems of research time,the research trend of grassland fire was finally analyzed,and the research difficulties and development trends of fire ecological factors on global climate change and fire prediction models were prospected.

Key words: Grassland fire, Ecological environment, Fire assessment and early warning, Fire review

摘要： 火作为重要的生态因子与我们的生活息息相关。国内外已对草原火展开了一定研究，本文讨论了草原火的研究成果，从影响因素、生态影响、时空分布格局、草原火的管理、遥感监控、预警和风险评价7个方面进行深入的探讨。一方面可为相关决策部门提供有力的科学依据，进而保证对草原火规范管理、草原生态环境平衡；另一方面，可为草原火发生发展过程，及其对相关区域乃至未来全球气候变化的影响研究提供依据，进而为当前全球变化研究做出贡献。由于目前在研究领域的局限性和研究时间间断性出现的问题，最后分析了草原火的研究趋势，并对火生态因子对全球气候变化影响和火灾预测模型有待深入的研究难点和发展趋势进行了展望。
