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

我们的研究涉及整理德岛县吉野川产生的有关人类和社会科学结构和自然特征的许多数据。由于日本河流工程的理念和方法正在发生巨大变化，因此对其进行了数据收集和分析，以确保其顺利转换。在吉野川流域，居民的关心行动正在积极开展。吉野川地区是河流项目的示范区，反映了居民的意见。我们的研究掌握了吉野川的基本动态数据。水坝建设和整治工程等河流工程，由于直接关系到居民的生活和财产，也由于存在利益冲突，经常引发严重的问题。此外，这些项目还伴随着自然环境的破坏以及农业和山村的崩溃。从反思的角度看， ...更多信息 r 1997年修订的法律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。吉野川项目的新框架正在形成，为了在居民的同意下推进河流项目，设想了以下程序：（1）分析河流流域的条件;（2）确定项目的目的;（3）审查各种项目方法;（4）综合评价项目方法的决策。这些程序需要大量的数据收集和分析。同时，对于具有不同价值观念和讨论能力的居民群体的参与，也需要新的分析和表达方法。这些合作研究收集了各种信息，并形成了数据库，以改善吉野川地区。我们的研究通过使用GIS方法将大量数据相互关联，并提供了许多数据，以促进居民对河流项目的理解和认同。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
