摘要：
With "3S" (GIS, GPS & RS) techniques as the background resource, remote sensing digital image management techniques as the support, and CBERS as the data, this paper explores CBERS data analysis of vegetation in the city of Zhengzhou. This design principally relies upon the CBERS image data from 2001 and 2006. Using ENVI, ERDAS, and ARCGIS to manage the data, it is possible to obtain two vegetation index thematic maps of Zhengzhou. The differences of the two maps show that the vegetation coverage of the urban areas of Zhengzhou city has expanded dramatically while the vegetation coverage and health degree have decreased in the northeastern and Southwestern areas.
