The purpose of this study is the regional difference for thermal influence of deforestation usig satellite data. The analyses are performed as follows ; 1) the relationship between land-use and surface temperature are calculated using Landsat TM data, 2) multi-regression equations between the rate of land-use for 1x1 km mesh and mean surface temperature for 1x1 km mesh are calculated. the equations express estimation of surface temparture, when land-use change, 3) standard multi-regression equations are calculated for comparison between the regional difference of deforestation. Landsat TM data are used for the analysis about Hokkaido (Tomaikomai, Sarobetu), Kantou (Fukusa), Sikoku (Kouchi) and Kyuushuu (Aso).The results are obtained that 1) the estimated surface temperature is the lowest on forest and the highest on city areas, 2) standard regression coefficients are constant for Kantou (Fukusa) and Sikoku (Kouchi) through all data but Hokkaido (Sarobetu). We recognized that thermal influence of deforestation is able to compare usig standard regression coefficients. Tlie range of standard regression coeficient is Tomakomai, Kouchi and Fukusa.

这项研究的目的是森林砍伐的热影响USIG卫星数据的区域差异。分析进行如下进行； 1）使用Landsat TM数据计算土地利用与表面温度之间的关系，2）计算1x1 km网格的土地使用率与平均表面温度在1x1 km网格之间的多回归方程。方程式表达表面频道的估计，当土地利用变化时，3）计算标准的多回归方程，以比较森林砍伐的区域差异。 Landsat TM data are used for the analysis about Hokkaido (Tomaikomai, Sarobetu), Kantou (Fukusa), Sikoku (Kouchi) and Kyuushuu (Aso).The results are obtained that 1) the estimated surface temperature is the lowest on forest and the highest on city areas, 2) standard regression coefficients are constant for Kantou (Fukusa) and Sikoku (Kouchi)通过除北海道（Sarobetu）以外的所有数据。我们认识到森林砍伐的热影响能够比较USIG标准回归系数。一系列标准回归型系数是Tomakomai，Kouchi和Fukusa。
