【摘要】 利用日本最北部Ｓａｒｏｂｅｔｓｕ平原地区的卫星热红外遥感数据对该区地表温度、植被指数及土地 利用状况等进行了分析。分析的结果表明，泥炭平原白天的地表温度比其他地带高，夜间则比其 它地带温度低。一般泥炭地的植被指数小，当有ＳＡＳＡ（矮竹状植物）生长后，植被指数增大。早 春和晚秋，地表面温度高低与植被指数大小的相关性弱，夏季则相关性强。因此认为可以根据泥 炭地表面温度数值来推测夏季的植物生物量。更多还原

【Abstract】 The analyses of Surface temperature, Vegetation Index and Land coverage at a peatland by Landsat TM data 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.更多还原
