Using forest management inventory data as data source, a visual individual tree cutting tree system was studied and developed based on WebGIS development system, using J2EE, Struts and Hibernate development frameworks. WebGIS was applied to reconstruct and visualize the attribute and spatial structure information of all individual trees in the subplots, which helps the users master forest resources more intuitively and specifically from the general to the local. This system has realized the functions not only browsing, querying and analysis of the individual trees and subplots, but also simulation of thinning in the upper storey, thinning in the lower storey, mechanical thinning, spatial thinning, selective thinning and clear cutting. Moreover, the system can compare the changes in attribute and spatial structure under these cutting scenarios. The operation of the system could provide a solution to forest cutting for forestry bureaus on individual tree level without additional data.%以森林资源二类调查资料为数据源,采用J2EE应用程度开发环境,借助Struts与Hibernate开发框架,研究和探讨了基于WebGIS技术的单株林木采伐可视化系统平台,对小班内全部单株林木信息和空间结构进行重建和可视化,使得用户从总体到局部都能更直观、更具体地掌握森林资源状况；该系统不仅能实现对单株林木和小班的浏览和查询等功能,而且能模拟上层疏伐、下层疏伐、机械疏伐、空间采伐、选择性采伐、皆伐等采伐场景,对比分析各种采伐场景下属性数据和可视化空间状态的变化,还能比较空间结构的指数变化,为各种采伐方案的对比分析和选择提供依据,为林业局等基层单位在不需要额外数据的情况下提供了基于单株水平的森林采伐解决思路和方案.
