摘　　要：思茅地区是云南省的重点林区。针对现有森林结构不尽合理的问题，应用系统分析的方法，建立合理的森林结构模型。采用经济效益、生态效益、资源持续利用、林地稳定性能和生产率５个指标，对森林结构中的地类结构、林种结构、年龄结构和树种结构等进行了分析研究。对合理结构与现状结构的差距进行比较，并提出系统优化的措施，为该区林业可持续发展提供参考。Simao prefecture is one of the key forest districts of Yunnan province.Aiming at the unreasonable forest structure,a reasonable forest structure model is set up by using the systematical analysis method.Several aspects of forest structure including forest land,forest category,stand age,tree species were analyzed and researched by adopting 5 indexes,those are economic benefit,ecological effect,sustainable utilization of resources,stability of forest land and productivity.The present structure is compared with the reasonable structure,and the measures to improve forest system are put forward.
