Quantitative assessment of forest landscape resources as an integral component of rural landscape and its applicability to landscape modification

为有序地开发和保护自然资源，必须制定林道发展的规划、环境和工程准则。在森林地区，修路是对环境破坏最大的活动之一，往往导致农村地区地貌特征的严重和不必要的退化。目前，本港并没有统一的单一及/或多用途道路的环境及工程设计标准。最初用于一种用途的道路往往后来被用于另一种用途。因此，如果考虑到以后可能发展的全部基础设施，最初的道路规划阶段/维修程序就变得非常重要。航空摄影是现代森林资源管理中进行的许多道路规划和资源清查活动的主要资料来源。传统的摄影测量数据采集过程以跨学科方法为特征，然而，可能B ...更多信息 e不足以解决今天与道路规划有关的所有环境保护问题，道路规划要求提供详细的、针对具体地点的、仔细定时的定量和定性信息。航空摄影作为一种类似的存储介质，可能并不代表有意义的信息。基于PC的图像数据处理软件，以确定现场调查数据在详细的空间背景下，最近变得负担得起。在这项研究中，通过应用于三重大学森林的初步道路网络计划以及陆地和/或海洋环境，利用航空摄影和数字正射摄影，本文对滋贺林区公路建设的水环境影响评价进行了总结，并对今后的作用进行了探讨。这些方法通过以下实例进行了说明：（1）通过判别函数分析进行土地覆盖数字分类和判读精度测量，（2）使用基于像素的聚合技术进行面积测量，（3）通过将图像数据处理系统与数字地形数据库系统相连接进行叠置分析，（4）识别影响路线定位的敏感站点，（5）道路廊道沉积物的空间分布估算;（6）缓冲区划分作为景观环境影响缓解的基础;（7）流域河岸带水环境影响评价。少

Planning, environmental and engineering guidelines for forest road development are necessary for the orderly development and protection natural resources. Road development is one of the most environmentally damaging activities in forest areas and often leads to serious and unnecessary degradation of landscape attributes of rural areas. At present, there are no uniform environmental and engineering design standards for single and/or multiple purpose roads. Roads that have originally been for one purpose are very often later used and upgraded for another purpose. The initial road planning phase/maintenance procedure therefore become very significant if the total infrastructure that may later develop is consider.Aerial photography is the primary source of information for much of the road planning and resource inventory activities undertaken in modern forest resource management. Traditional procedures of photogramtric data gathering characterized by interdisciplinary method, however, may b … More e insufficient to address all of today's environmental protection issues concerned with the road planning, which claims detailed, site-specific, carefully timed quantitative and qualitative information. Aerial photography as a type of analogous memory medium may not represent meaningful information. PC-based imagery data processing software to identify site investigation data in a detailed spatial context have recently become affordable.In this research, the tactical phase of a PC-based imagery data processing system using aerial photography and digital orthopotography through the application to preliminary road network plans in Mie University Forests and also to terrestrial and/or aquatic environmental impact assessment of forest road constructed in Shiga prefecture has been summarized, and some prospective roles discussed. The approaches are illustrated using examples of (1) digital classification of land cover and interpretation-accuracy measure by discriminant function analysis, (2) area measurements using a pixel-based aggregation technique, (3) overlay analysis through linking an imagery data processing system to digital terrain database system, (4) identification of sensitive sites influencing route location, (5) estimating spatial distribution of sediment from road corridor, (6) buffer zoning as the building blocks for environmental impact mitigation of landscape, and (7) aquatic environmental impact assessment for riparian zone in drainage area.
