説明
This paper aims to clarify the effectiveness and the problem of the current landscape conservation system based on small watershed unit. The survey area is Yokohama city. We first prepared datasets of landuse in 1945, 2004 and in three scenarios of the administration of the landscape conservation system, and calculated the percolation of rainwater of each small watershed as an environmental indicator. Then, using the result of all cases as indices, we classified the small watersheds by the cluster analysis in order to analyze the relationship between the landscape conservation system and the environmental change. The study revealed the following: (1) In 1945, most of the small watersheds in Yokohama City had high capacity of watershed protection. However, there are only a few small watersheds maintaining the same condition in 2004. (2) The small watersheds were classified into eight groups. (3) In the watershed protection area, we identified forest areas in riverhead, farming areas and urban areas which include slope forests. (4) Urbanization control has played an important role in maintaining the environment. However, there is not enough conservation system for small green spaces in urban areas.
