摘　　要：针对农业领域的信息化建设,提出了将Bezier曲线算法应用到农业GIS中。并根据Bezier曲线在林业资源数字化研究中的应用,建立了相应的数学模型,编制相应程序。通过对实际林业资源中珍稀植物位置数据的处理,提高了图形生成效率,为掌握珍稀植物资源情况,划定保护区提供帮助。目前,GIS的应用范围相当广泛,己经在农业土地水资源规划、林业管理、自然资源调查、环境保护等各领域建设成不同的GIS系统,GIS在农业上的应用是当今农业科学中一个新的重要研究领域,如林业资源管理中开发出许多基于GIS的决策支持系统。As the information construction of agriculture,the Bezier curve algorithm is applied to the GIS in agriculture. In the research of the forestry resources digitization based on the Bezier curve,the mathematical model is established and corresponding program. As processing the actual forestry resources of rare plant location data,improve the efficiency of Graphics formation,to grasp the rare plant resources information,to offer help for delimiting protected areas. At present,the application scope of GIS is quite widespread, has been in various areas of agricultural land water resources planning,forestry management,a survey of natural resources, environmental protection and other construction into different GIS systems,the application of GIS in agriculture is in agricultural science today a new important research fields,such as forestry resource management in the development of many GIS based decision support system.
