项目摘要

Dealing with the sophisticated issues of integrating forest resources management with environmental, and social values and objectives in a sustainable manner requires a more holistic and spatial approaches than has been traditionally applied to managing forest ecosystem condition at a stand level. By taking a landscape perspective, combined with improved analytical tools to support the consensus-based management decision-making, benchmarking forest management practices to meet the adequate scale or level of potential impacts caused by silvicultural and harvesting activities might be realized. The object of this research was to discuss the development of a GIS-based spatial decision support system combined with image processing facility (raster type GIS system, IDRISI 32) and a harvest schedule/allocation model for landscape perspective concerns (HARVEST). GIS has now made it possible to incorporate spatial components into harvest schedule/allocation planning and simulation models. In some cases, the modeling capabilities of a particular GIS may be used directly to aid decisions about timber harvesting ; in other cases, an external model is linked to a GIS database. HARVEST was designed to predict changes in landscape patterns with spatial attributes resulting from the initial landscape conditions and potential timber harvest activities. Application potential at two case study forests in Mie and Shiga Prefecture was showed through examples of predicting these changes combined with technical opportunities, constrains, and trade-off. The outcome (the resulting patterns of forest openings and stand age distributions) also provided opportunities of visual feedback. This approach would enable resource managers to design and demonstrate the long-term conservation outlook of forest resources under alternative management strategies geared to multiple economic, environmental, and social objectives.

以可持续的方式处理将森林资源管理与环境和社会价值及目标结合起来的复杂问题，需要采取比传统上在林分一级管理森林生态系统状况更全面和更空间化的办法。从地貌景观的角度出发，结合改进的分析工具，支持基于共识的管理决策，就有可能实现森林管理做法的基准化，使造林和采伐活动所造成的潜在影响达到适当的规模或水平。本研究的目的是讨论开发一个基于GIS的空间决策支持系统结合图像处理设施（栅格型GIS系统，IDRISI 32）和收获计划/分配模型景观前景的关注（HARVEST）。地理信息系统现在已经能够将空间部分纳入收获时间表/分配规划和模拟模型。在某些情况下，一个特定的地理信息系统的建模能力可以直接用于帮助决策木材采伐;在其他情况下，一个外部模型链接到一个地理信息系统数据库。HARVEST的目的是预测景观格局的变化与空间属性导致的初始景观条件和潜在的木材采伐活动。通过结合技术机会、约束和权衡预测这些变化的实例，展示了三重县和滋贺县两个案例研究森林的应用潜力。结果（由此产生的森林开放和林分年龄分布模式）也提供了视觉反馈的机会。这一办法将使资源管理人员能够设计和展示在针对多种经济、环境和社会目标的替代管理战略下森林资源的长期养护前景。
