For making full use of the resources of the territory, Japan put the afforesation as a basic policy in the pretection and development of the territory and adopted a series of measures in investing the resources of forestry, formulating the program of the development of forestry, establishing shelter forest system, preserving the eclogic balance, afforesting and managing scientifically with a comprehensively development, Japan has become one of the forestry-developed countries with the rate of forest cover of 68%.

日本是太平洋西部的一个群岛国家,地理环境复杂多样,陆地75%是山地丘陵,自然灾害较多。日本为了优化利用国土,把植树造林作为国土整治的基本国策,综合发展林业,森林覆盖率达68%,成为世界上林业发达国家。日本在森林调查、森林规划、造林、育林等方面积累了许多经验。大连的造林环境和日本相(?),但是大连林业还很落后,为了恢复和保护生态平衡,整治国土,应借鉴日本发展林业的经验。查清森林资源现状、林况、地况,制定林业规划并保证实施;调整林业结构,建立以水土保持为中心的防护林体系;因地制宜采取多种方法造林、育林,精选良种,精心抚育,科学营林,以林养林;重视林业科技成果的推广和应用;加快大连林业建设的步伐,造福子孙后代。

The middle-long term planning and decision-making for forest ecological system management was studied taking Dongfanghong forest farm Dailing forest bureau for example.The The planning took resuming district climax community as the forest management objective, and set up objective function with distance index that indicates term when forest types would make succession to be corresponding district forest climax community Based on the natural forest management and forest succession models in the area. tile forest farm was divided into 8 groups of forest management types. Decision variables and restrain condition were analyzed and defined and solution for the problem was got with mathematicalprogramming. The authors point out that the planning can give consideration to both of economic and ecological benefits. and adapting management and integrated forest planning system can control the risk in the forest planning.

以带岭林业局东方红林场森林为例。进行了中、长期的森林生态系统规划决策的研究。在规划中以恢复地带性顶极群落作为经营目标.以各种林分类型向相应的顶极群落演替所需要的相对时间长短作为距离系数建立目标函数。在研究了该区域天然林经营与演替模型基础上.把东方红林场森林划分为8个森林经营类型组,分析和定义了决策变量及约束条件,进行线性规划求解。研究结果认为.这种森林规划兼顾森林的经济和生态效益,适应性经营与一体化森林规划体系是控制和纠正这种森林规划风险性的技术手段。

Forest management decisions are made based on spatial\|temporal information about both current and future forest resource conditions. It is a big challenge to track and project changes in forests, a long\|lived dynamics biological systems, that are continuously changing. The uncertainties and complexes in managing the forests over time demand for more useful and timely information. So spatial\|temporal information becomes the cornerstone of effective forest management decision\|making. Traditional techniques cannot be used to solve sophisticated problems of forest planning and management at large spatial scales. Geographical Information System(GIS), the computer\|based analytic toolbox for quantitatively modeling of spatial relationships and mapping system, plays an important role in providing the comprehensive spatial information for forest management. This paper reviews the current literature regarding GIS applications in forest planning and management, and discusses benefits, problems and limitations of GIS in forest practices. Furthermore, recent progress and future development in integrating GIS with other spatial technologies such as Remote Sensing (RS), Global Position System (GPS), and modeling approaches including artificial neural networks and forest simulation models into forest decision support systems are also discussed.

森林经营决策必须建立在现在和未来森林资源的时空分布信息基础上 ,而跟踪和获得森林资源信息的变化极具挑战性 ,因为森林资源是一个处于持续不断变化的动态生态系统 ,它的不定性和复杂性决定了森林经营需要更有用的和更及时的信息 ,因此时空信息是进行有效森林决策的基石 .现有的传统技术已满足不了大规模的森林规划和经营的需求 .地理信息系统是基于计算机基础之上的分析工具 ,能为森林经理提供复杂的空间信息 ,并建立定量模型 .本文综述了地理信息系统在森林经营方面的应用 ;指出了地理信息系统在林业中的效益、问题和局限 ;分析了地理信息系统在同其它空间技术如遥感、全球定位系统、人工智能建模、决策支持系统等方面的最新进展与发展方向
