This paper describes the way to extract information of gold anomaly in high vegetation coverage area through a case study from the Qiyugou gold ore deposit and its environs, Song county, Henan Province. Principal component analysis,false color composite,stretch histogram and supervise classification were analyzed on the remote sensing images using ENVI4.8 software. It is suggested that the linear structure,which is delineated using convolution filter and morphological analysis method,is characterized by statistical self-similarity and fractal geometry.It is found that the high value of fractal dimension is roughly coincident with the gold anomaly of vegetation by comparison of the contour maps of plant geochemical anomaly and fractal dimensions calculated by box-counting method.By comprehensive analysis of stratigraphy,igneous rocks,gold mineralization,fractal dimension of linear structure and vegetation anomaly from remote sensing,nine exploration targets with three levels of probabilities are figured out.
