The purpose of this study is to estimate how green has been changed in Kyoto city using remote sensing. As for estimation of green, we use two methods. 0ne is quantity of greenery and the other is quality of them. In this reserch, we define change of the rate of water in leaves as vegetation vigor, the quality of vegetation has been grasped using Vegetation Vigor Index(VVI'). In that case, VVI' which is Vegetation Vigor Index was created by measuring the reflective characteristic of leaves. At the same time, green cover rate which is a green quantity has been grasped using a land cover classification. The results are as follows: (1) By using VVI', we were able to distinguish vegetation vigor with vegetation cover rates. (2) We were able to check that VVI' shows change of Vegetation Vigor from the drought in 1994. Therefore, we could catch quality of green in addition to quantity of green by using VVI'.
