摘　要：根据马尾松单木生长量模型，运用动态模拟方法，以Windows98为操作平台，以VisualC++为开发工具，研制了马尾松林抚育间伐的计算机决策系统.系统可以根据用户的需要，分别以林分最大蓄积量、最大生物量或最大货币收益为经营目标，求解在各种间伐体制下各龄阶的最适经营密度.模拟结果表明：适时间伐明显促进了林分的生长，且立地质量越好，间伐所产生效益越显著.

Abstract：Using the Windows 98 as the operating platform and the Visual C++ as the software development kit, we developed a computer decisio n-making system for intermediate cutting of Pinus massoniana based on the s ingle tree increment model of Pinus massoniana with a dynamic simulated meth od. This system can help you get the optical operating density of every age clas s of all kinds of intermediate cuttings by setting the maximum amount of growing sto ck or the maximum biomass or the maximum net income as the target of forest mana gement according to the demand of users. The simulated results show that stan d grows faster under proper cutting, and that the effects will be bette r under better site conditions.
