The analyses of Surface temperature, Vegetation Index and Land coverage at a peatland by Landsat TMdata demonstrate that the surface state and the surface temperature is influential by Vegetation. From the analysis of Landsat TM data the following is demonstrated. 1. The growing of Sasa lowers the surface temperature. 2. The surface temperature decreases with the increase of Vegetation Index. 3. The relationship of surface temperature and Vegetation Index in summer can be presented as: Ts= (-14~-18 )VI + (30~40) therefore, biological amount in summer may be estimated from the surface tern perature.
