A study on the regional structure of the Yoshinogawa drainage by GIS(Geographical Information System) methods

我们的研究致力于整理德岛县吉野河(Yoshinogawa)产生的许多关于人类和社会科学结构和自然特征的数据。由于日本河流工程的理念和方法发生了很大的变化，为使其顺利过渡，进行了数据收集和分析。在吉川流域，居民的关注行动正在积极开展。吉川地区是反映居民意见的河流项目样板区域。我们的研究掌握了吉野河的基础和动态数据。水坝建设和整治工程等河流工程经常造成严重麻烦，因为它们直接关系到居民的生命财产，而且存在利益冲突。此外，这些项目还伴随着对自然环境的破坏以及农业和山村的坍塌。从反思的角度来看，…河1997年修订的《反垄断法》采用了新的理念和方法。因此，项目发起人和居民之间的冲突正在化解，他们之间的合作正在发展。吉川项目正在安排一个新的框架。在居民同意的情况下推进河流项目，假定如下程序：(1)河流流域条件分析，(2)项目目的的确定，(3)各种项目方法的审查，(4)项目方法的综合评价决策。这些程序需要大量的数据收集和分析。此外，还需要新的分析和表达方法来让许多居民参与进来，他们具有不同的价值观和参与讨论的能力。这些合作研究收集了各种信息，并形成了数据库，以改善吉川地区的状况。我们的研究利用地理信息系统的方法，将大量的数据相互关联，为居民对河流项目的理解和认同提供了许多数据。较少

Our studies are concerned with organizing many data about human and social scientific structures and natural characters, which are produced by the Yoshinogawa (Yoshino River) in Tokushima Prefecture. As philosophy and method of Japanese river projects are widely changing, data collection and analysis are made for their smooth changeover. In the Yoshinogawa drainage area, concerned actions by the residents are actively developed. The Yoshinogawa area is a model area of the river project, which reflects residential opinions. Our studies grasped fundamental and dynamic data about the Yoshinogawa.River projects such as dam constructions and improvement works have caused serious troubles frequently, because they are directly connected with residential lives and properties, and because they connote a conflict of interests. Furthermore, the projects are accompanied with destruction of natural environment and collapse of farming and mountain villages. From the viewpoint of reflection, the Rive … More r Law that was revised in 1997, adopted new philosophy and method. As a result, conflicts between project promoters and residents are being dissolved, and cooperations between them are being developed. A new framework of the Yoshinogawa projects is being arranged.For promoting the river projects with agreement of the residents, the following procedures are assumed ; (1) analysis of conditions of river drainage area, (2) setting of purpose of projects, (3) examination of various project methods, (4) decision making of project methods with synthesized evaluation. The procedures require enormous data collection and analyses. Furthermore, new analyzing and expressing methods are required for participating of many residents, who have various sense of value and various abilities concerning discussions. These cooperative studies collected various information and formed database, for improvement of the Yoshinogawa area. Our studies related enormous data with one another by using GIS methods, and presented many data for contributing residential understanding and agreement with the river projects. Less
