High-resolution satellite image data that has been available recently might be useful enough for analyzing vegetation in urban zone. In this research, firstly, two types of satellite image data are compared. One is IKONOS that is expected to be more common in several studies, the most detailed currently. The other one is LANDSAT that has been used frequently for precedent urban vegetation land-use analysis. As for urban space is finite, to give the residents a feeling of satisfaction, Land Planner should grasp accurate measurement of urban land-use pattern and vegetation indexes and make a sophisticated plan to realize it. So secondly, with the soft ware of ERDAS, we analyze distribution situation of rather large-scale green field as park zone, roadside tree, private garden and rather detailed vegetation zone in Nagoya and Saga City. Furthermore, the vegetation calculation indexes, GCI, GDI are proposed here. The main results are as below ;1. The vegetation distribution of the surface of Nagoya city is distributed roughly relatively than one of Saga City.2. The vegetation around the commercial land-use zone is however comparatively concentrated though the degree of green is rather short.3. The vegetation around the residential land-use zone is however relatively dispersed though the degree of green is rather large.These tendencies might be caused from the existence of much detailed, discontinuous and segmentalized vegetation zones as private gardens over Nagoya urban district.

最近可用的高分辨率卫星图像数据可能足以分析城市区域的植被。在这项研究中，首先将两种类型的卫星图像数据进行比较。一种是ikonos，预计在几项研究中更为普遍，这是目前最详细的。另一个是Landsat，它经常用于先例的城市植被土地利用分析。至于城市空间是有限的，为了使居民有满足感，土地规划师应掌握对城市土地利用模式和植被指数的准确测量，并制定一个复杂的计划来实现这一目标。其次，借助Erdas的软件，我们分析了纳戈亚和萨加市的公园区，路边树，私人花园和相当详细的植被区，分别是大型绿地的分布情况。此外，这里提出了植被计算指数，GCI，GDI。主要结果如下； 1。纳戈亚城表面的植被分布比萨加市的一个大致相对较大。2。然而，尽管绿色程度相当短，但商业土地使用区域周围的植被却相对集中。3。然而，尽管绿色的程度很高，但在住宅用途区域周围的植被相对散布。这些趋势可能是由于存在着详细，不连续和分割的植被区作为纳戈亚城市地区的私人花园而引起的。
