摘　　要：利用削度方程编制材种出材率表是目前出材率表编制的发展趋势,分析当前计算机理论造材在编制材种出材率表时存在通用性低、灵活性差、交互性弱的问题。为了满足林农灵活造材需要,提出了通用理论造材技术并进行研究。对计算机理论造材进行需求分析,设计了系统的功能结构、理论造材技术流程、各区分段造材流程和相应的数据库结构,采用Arc Engine技术和C#编程技术实现了相应功能并进行应用。结果表明,通用理论造材技术效率高、成本低、使用灵活,林农可以针对不同树种、不同造材方案灵活造材并预估相应收益。计算机应理论造材技术为各基层森林经营单位快速编制材种出材率表提供技术支撑,对单株活立木造材动态监测和收益预测更加直观、准确。The application of taper equation is the developmental trend for compiling the rate of merchantable volume table.Problems existed in compiling the rate of merchantable volume table by computerized theoretical bucking were pointed out,such as low generality,poor flexibility,and weak interactivity.In order to meet the needs of flexible bucking to forest farmers,a general theoretical bucking technology was put forward and examined.Through the requirement analysis of general theoretical bucking,the paper designed the functional structure,technological flow of general theoretical bucking,flow of theoretical bucking in each section,and database design.The corresponding functions were realized and put into practice by using the Arc Engine technology and C#programming technology.The results showed that the general theoretical bucking was high in efficiency and low in cost,and flexible in use.The forest farmers could flexibly conduct the theoretical bucking to estimate the corresponding income according to the different species,and different bucking schemes.Computerized general theoretical bucking technology could provide technical support for primary forest management units to rapidly prepare the rate of merchantable volume table,at the same time the technology made it more accurate to conduct dynamic bucking monitoring and yield prediction of individual standing tree.
