A study about analysis method of "Yama-ate" in the Castle Town and Colonist City in Hokkaido

“山食”是城堡城镇的一大美学特征，指的是从城镇的主要街道上就能看到顶峰的景观现象；然而，具有设计意图的城镇布局方法迄今尚未得到验证。本研究从城堡城镇和殖民主义城市的几个案例入手，利用地理信息系统和全球定位系统机制分析实际情况，有助于高精度地测量景观构成，具有数学值、公正性和客观性。然后，通过把握街道和街道所面对的山体的特征，对设计进行假设研究。也就是说，主要街道是如何设计成城堡城镇的框架，如何进行防洪以翻新河流和护城河，规划的关键形状或弯曲的道路；城堡大门和神殿或寺庙是如何建造的，以适应轴心。所有这些问题，在设计方法和背后的意图方面，都需要表现出来。

"Yama-ate" is a major aesthetic feature of Castle Towns, referring to the landscaping phenomenon that the crowned mountaintop can be seen from the town's main street; yet, the methods to lay out towns with design intention is hitherto unverified.This research starts to target several cases of Castle Town and Colonist City, analyzing the actual conditions by executing GIS and GPS mechanism, which contribute high-precision measurement of the landscaping composition, with mathematic values, unbiased and objective.Then, by grasping the characters of the street and the mountain to which the street faces, it sets up a hypothetical study on the design. Namely, how was the main street designed to be the castle town's framework, the flooding control done to renovate rivers and moats, the Key-shaped or bended road planned; and how were the Castle Gate and Shrine or Temples built to fit the Axis. All these questions, in terms of design methods and the intention behind, are to be made manifest.
