摘  要：
为实现人工林的近自然化改造,以帽儿山樟子松人工林为研究对象,以可视化模拟为手段,以林分空间结构优化为目标,以常用空间结构参数(角尺度、混交度、大小比)为切入点,按照森林演替的一般规律构建樟子松人工林的空间结构优化方案,并将其与林分三维可视化模拟模型进行耦合,建立樟子松人工林三维可视化经营模拟系统。模拟实例表明:林分的平均角尺度从0.461提高到0.487,林木分布格局由均匀分布变为随机分布;林分混交度由0.284上升到0.308,混交程度得到提高;林分大小比由0.515变为0.481,林木个体生长的优势程度得到提高;基于林分空间结构的择伐,使林分空间结构得到了显著优化。该系统可以在虚拟森林环境中实现对森林经营过程的模拟、经营方案的评价和优化、林分未来生长状况的预测以及森林经营活动对林分结构的影响,为我国人工林的科学经营和管理提供一个全新的平台。

摘  要：
To realize close-to-nature transformation of plantations,in the paper,with the Pinus sylvestris var.mongolica plantations in Mao'ershan as the research object,and from the viewpoint of forest spatial structure optimization and methods of forest visualization simulation were studied,and the model of spatial structure optimization for Pinus sylvestris var.mongolica plantations,which was based on the basis of the general rule of forest succession,was developed on spatial structure parameters,i.e.mingling degree(M),neighborhood comparison(U) and uniform angle(W) index.Then three-dimensional(3-D)visualization management simulation system of Pinus sylvestris var.mongolica plantations was established by combining the model of spatial structure optimization with the model of stand visualization simulation organically.The results of simulation examples showed that the mean value of uniform angle index turned into 0.487 from 0.461,indicating the stand structure was changed from uniform distribution to random distribution.And the mean values of mingling degree was raised from 0.284 to 0.308,improving the mingling degree.Meanwhile,the mean values of neighborhood comparison from 0.515 to 0.481,the advantage degree of individual tree growth was improved.The forest spatial structure are optimized after the cutting which based on stand spatial structure.The system can achieve the simulation of forest management process in virtual forest environment,evaluate and optimize forest management plan,and predict future growth condition of stands,as well as,the influence of forest management activities on the forest conditions,etc so it was possible to offer a new platform for forest resource scientific management and business.
