项目摘要

This research was attempted to clarify the relation between the actual condition of urban and green areas and land-use control systems in Japanese and Korean provincial cities which have contrastive urban forms. Landsat TM data and image analysis processing were used for quantitatively comparative analysis. The results are as follows :1.Using two types of supervised classification techniques of Landsat data, that are post-classification comparison and pixel-to-pixel comparison by principal component analysis, I tried to detect land use change. This enabled a quantitative analysis of land use change in Japanese and Korean cities, which was difficult for the constraint of collecting land use data.2.From the analysis of the results of the classification and Normalized Vegetation Index, it was observed that Korean cities (Mokpo and Ulsan) include more green area near the city center than Japanese one (Toyohashi), and the difference between Japan and Korea in urban form and land use control system influences the scale of mass green area.3.From the analysis of the relation between zoning designation and land use change, the following findings were shown ;(1) In the Korean cities, there are about 85% of built-up area and about 25% of green area within urban land use promotion area. But in Toyohashi, there are about 35% of built-up area even within urban land use control area and the rate of green area in urban promotion area decreases to less than 10% in 1993.(2) In the Korean cities, there is an obvious difference between urban land use promotion and control areas in vegetable activity, but in Toyohashi the similar activity is observed in both areas.(3) The zoning designation and the distance from the city center influences the difference in the distribution of the green coverage rate within the urban areas in all of the cities. Moreover, The influence is becoming stronger.

本研究旨在厘清城市形态截然不同的日本与韩国省级城市的城市绿地实际状况与土地利用管制制度之间的关系。采用Landsat TM数据和图像分析处理进行定量对比分析。研究结果如下：1。利用Landsat数据的两种监督分类技术，即分类后比较和主成分分析的像素间比较，我试图检测土地利用变化。这使得对日本和韩国城市的土地利用变化进行定量分析成为可能，这是由于收集土地利用数据的限制而难以做到的。通过对分类结果和归一化植被指数（Normalized Vegetation Index）的分析发现，韩国城市（木浦和蔚山）市中心附近的绿地面积比日本城市（丰桥）多，日本和韩国在城市形态和土地利用控制制度上的差异影响了大规模绿地面积的规模。通过对分区与土地利用变化关系的分析，得出以下结论：(1)韩国城市土地利用促进区内约有85%的建成区和25%的绿地。但在丰桥，即使在城市土地利用控制区内，建成区也有35%左右，城市促进区内的绿化面积率在1993年下降到不足10%。(2)在韩国城市中，城市土地利用促进区和控制区在蔬菜活动方面存在明显差异，但在丰桥，两个地区的蔬菜活动情况相似。(3)区域划分和距离城市中心的距离影响了各城市城市绿地覆盖率分布的差异。此外，影响力越来越大。
