林分可视化系统(Stand Visualization System,SVS)是模拟林分的生长状况、空间分布以及预测林分未来发展趋势的三维可视化软件。本文利用对长江上游防护林重点建设区绵阳官司河流域马尾松林林分调查数据,采用林分可视化系统展示马尾松林林分可视化流程,并对样地树高分布图、样地径阶分布图、样地冠幅比分布图、样地森林覆盖率等林分信息图进行了分析和讨论,对于官司河流域马尾松林资源管理具有重要的意义。
Stand Visualization System (SVS) is a three-dimensional visualization software that simulates the growth status and spatial distribution of stand and forecast the future development of stands. Based on the survey data of Pinus massoniana forest in Mianyangguosi River Basin, a key construction area of the upper reaches of the Yangtze River, forest visualization system was used to display the visualization process of Pinus massoniana forest, and the distribution pattern of tree height, The distribution of crown-to-crown ratio, forest coverage of plots and other forest information maps were analyzed and discussed, which is of great significance for the management of Pinus massoniana forest resources in Guansi River Basin.
