A Study on Historical Evaluation in backmarsh landuse

该研究涉及与断崖线以下河流沿岸的沼泽有关的湿地管理。这些湿地有多种用途，如捕鱼、水生植物养殖和防洪水库。这些与高原周围的树林一起，是关东平原乡村景观的基本要素之一。此外，这些无疑为生态孵化提供了关键的场所。特别是战后经济增长后，由于稻田的扩张和城市化的蔓延，作为景观中引人注目的元素的后沼泽湿地逐渐被开垦和消失。这项研究选取了关东平原北部古贺市附近的一个湿地。通过地形结构、基础设施和文化组织三层的多层次地理方法进行历史分析。首先发现这三种结构在湿地消失前呈现同构重合。第二个观察是这样的，这种巧合在消失后变得不稳定和模糊。第二阶段研究的目的是在启动公园项目的范围内制定湿地恢复计划。该规划基于三个原则，即忠实于原始地形特征，尊重历史遗产，创造社交休闲场所，如餐厅或博物馆。这些原则与围绕寺庙开发的日本传统“美正公地”的固有原则相吻合。此外，值得注意的是，在这个公园里，有100多个几乎被遗弃的小地名被重新引入。这有望在该公园产生空间脚本复合景观文本。

The study deals with wetlands management related to backmarshes alongside rivers extending below the bluff lines. These wetlands have been serving for multiple uses such as fishing, waterplant culture, and flood control reservoirs. These, with surrounding groves on plateau, were one of the essential elements for rural landscape in the Kanto plain.Further, these were providing undoutedly critical spots for ecological incubation. The backmarsh wetlands, constituting conspicuous elements in landscape, have been reclaimed and disappearing little by little particularly since the post war economic growth either for the purpose of expansion of rice fields or sprawling urbanization.The study picks up one of these wetlands beside the city of Koga in the northern Kanto plain.Historical analysis was carried out through a multi-layered geographical approach constituting of three layers, namely those of topographical structure, infrastructure, and cultural tissues.It is found first that the three structures showed isomorphical coincidence before disappearance of the wetland. Second observation is such that this coincidence became unstable and blurred after its disappearance.The second phase of study was aiming at making restoration plan of wetlands under the scope of launching a park project. The plan is made based on three principles, i.e. fidelity to original topographical feature, respect of historical heritages and creation of sociable amenity spots such as restaurant or museum. These principles coincide with those inherent to Japanese traditional Meisho Commons developed around temples. Further, it might be worthy of noting that over one hundred small place names almost abandoned have been reintroduced in this park. This is expected to produce space-script compound landscape text in this park.
