Satellite data was regarded as a main information source by many key projects in forestry for the past 20 years. such as the comprehensive inventory of remote sensing in "Three north" protection forest, monitoring and assessing on forest fire, evaluation Yunnan provincial tropical forest in southwest China, assessing forest ecological effect, preventing desertification, monitoring insects and innovating on current forest resources survey system, etc. Under the support of computer techniques and models, a relationship was established between remote sensing data and forest environmental factors, so they can express and estimated with quantitative methods. The satellite data being used include TM.. SPOT NOAA ERS-1 and Radarsat. This paper aims to introduce the application ofsatellite remote sensing data in Chinese forestry, especially the methods of estimating for growing stock volume, appraising the efficiency of using remote sensing data, estimating forest fuels with remote sensing, discovering early and assessment on forest fire, as well as brief introduction of remote sensing application in ecological forestry forest environment and forestry division. All ofwork mentioned in this paper is special achievements of Chinese forestry experts.
