Comparative Analysis of Urban and Green Areas Between Japanese and Korean Provincial Cities Using Landsat TM Data

本研究试图阐明日本和韩国具有对比城市形态的省辖市的城市和绿色区域的实际状况与土地利用控制系统之间的关系。利用陆地卫星TM数据和图像分析处理进行定量对比分析。主要研究结果如下：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元间比较，对土地利用变化进行了检测。这使得对日韩城市土地利用变化的定量分析成为可能，这是由于土地利用数据收集的限制而难以实现的。2.从分类结果和归一化植被指数的分析中可以看出，韩国城市的土地利用变化木浦和蔚山在市中心附近有比日本更多的绿色区域（Toyohashi），以及日韩两国在城市形态和土地利用管制制度上的差异对块状绿色用地规模的影响。（1）在韩国的城市中，约85%的建成区和约25%的绿色区位于城市土地利用促进区内。但在丰桥，即使在城市土地利用管制区内，也有约35%的建成区面积，1993年城市促进区的绿色面积比例降至10%以下。(2)在韩国城市中，城市土地利用促进区和控制区的蔬菜活动存在明显差异，但在丰桥，在两个地区观察到类似的活动。(3)分区设计和距市中心的距离影响了所有城市城区内绿色覆盖率分布的差异。而且，影响力越来越大。

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.
