Abstract  Vegetation, as the comprehensive reflection of climate and other environmental elements, is closely related with climate changes. The article, on the basis of Holdridge life zone index method and the unsupervised classification method, the climate data, NDVI data and DEM data in 1982, 1992 and 2002 of the research area as well as the multi-source information after amalgamation, undertakes unsupervised classification and concludes the vegetation coverage changing map from 1982 to 2000 in the Huanghe-Huaihe-Haihe area after post-classification processing, space analysis and data development. According to the result, the vegetation coverage change was slowly in the past nearly 20 years and the vegetation has remained almostly consistent. The areas with relatively fierce changes are mainly located at the meeting part between the 1st and 2nd terrain stages, at the area around the 400 mm annual precipitation line, at the hill area in Shandong and the lower reach area of the Huaihe River.
Key words:  Holdridge unsupervised classification      Huanghe-Huaihe-Haihe area      multi-information      vegetation cover change
