基于GIS的森林资源信息管理关键技术

用现代高新信息技术对森林资源信息进行科学、高效地管理,为森林资源可持续经营战略决策搭建先进的技术支撑平台,是森林资源可持续经营研究的重要内容.根据目前森林资源信息管理存在的问题和现状,以火地塘林场为例,探讨对森林资源信息进行科学管理的两个关键技术:(1)基于GIS集成管理图形数据和属性数据;(2)建立资源模型库,运用模型实施森林资源数据的动态更新和预测.从而避免了传统的森林资源信息管理方法中存在的一些问题,更加有利于指导森林资源的可持续经营.

Key Techniques on Forest Resource Information Management Based on GIS

It is very important to take effective measures to ensure scientific management of forest resource information and sustainable management of forest resources. Taking Huoditang Forest Farm for a typical example, this paper probes into some main problems of forest resource information management, and then puts forward two key techniques beneficial to scientific management of forest resource information. They are: (1) Graphic data and attribute data should be integrated to be managed on the basis of GIS; (2) A model database should be set up, with which the forest resource data can be dynamically updated and the change of resources can be predicted in the future. Thus the sustainable management of forest resources can be further developed.
