Developing efficient and low energy consuming biomass carbon industry would be a final solution of these bio-wastes and for producing carbonized products to reuse the min agriculture and to satisfy municipal energy demand sin agriculture production and rural life.In this paper，the main organic waste as feedstock and the main process for bio-char production were reviewed. The physicochemical properties of bio-char such as the element content，alkalinity，surface characterization and the microscopic pore structure were introduced. Also，the potential application of bio-char in the field of agriculture and environment was summarized，such as the utilization of soil conditioner for improving fertility，enhancing carbon fixation and reducing greenhouse gas emission，and as an effective adsorbent for removing heavy metals and organic pollutants from wastewater,and the future research direction of bio-char was forecasted finally. Key words Agricultural solid waste ,Bio-wast reuse,Bio-char 摘要：我国农田秸秆和生活垃圾等农业和农村有机废弃物面广量大, 其资源化处理一直没有得到根本性解决，而生物质炭作为一种多功能性材料正逐步受到人们的广泛关注，因此开发高效低耗有机废弃物生物质碳工程转化产业化技术, 以新型碳质产品就近回田回村实现农业循环,而服务于农业生产和农村生活, 可能是农业和农村有机废弃物循环利用并促进农业固碳减排的最佳解决方案。本文综述了以农业固体废弃物为原料制备生物质炭，给出了制备生物质炭的主要工艺，并对生物质炭的主要物理化学性质如元素组成、碱度、表面特性和孔隙结构进行了介绍。然后对生物质炭在农业和环境领域中的应用做了相应介绍，例如用作土壤改良剂提高土壤肥力、增加碳固定、减少温室气体排放，作为一种高效吸附剂同时去处污水中重金属及有机污染物等，并对生物炭的前景做出了展望。
