我国林业过去曾经实行过大砍大造的方针,导致全国范围的生态灾难和林区的经济困境。当前正在实施的天然林保护工程和退耕焕还林工程是在我国山地森林应用生态系统管理的良好时机。针对长白山地区天然林的保护与经营,我们建立了一个决策支持系统,简称为FORESTAR。它是以林业局为单位、用GIS框架下的森林资源清查数据建立的。最初的版本包括两个子模块:森林采伐设计和森林恢复经营。在每个子模块下,用户可以比较各种决策条件下的效果,以便从中选优。这个决策支持系统可以用来帮助各级林业工作者实现上下一致的、多目标的森林经营管理规划。图2参17。
In the past, China’s forestry policy of cutting costs and cutting costs has led to the nationwide ecological disasters and the economic hardships in the forest areas. At present, the implementation of natural forest protection projects and the project of reforesting forests with reforestation are good opportunities for the management of the ecosystem management of mountain forests in our country. For the protection and management of natural forests in Changbai Mountain area, we have established a decision support system, referred to as FORESTAR for short. It is based on the Forestry Bureau as a unit, using forest resources inventory data under the GIS framework. The original version consisted of two sub-modules: deforestation design and forest restoration. Under each sub-module, users can compare the effects of various decision-making conditions in order to select from them. This decision support system can be used to help forest workers at all levels to achieve consistent and multi-objective forest management planning. Figure 2 Senate 17.
