This article presents some common used image fusion ways,they are major constituent fusion method,Brovey transformation fusion method,and amendatory IHS fusion method.At last this paper brings forward IHS which based on brink enhancing. Taking ETM data of Lianlan area of Qinghai province for example,the three ways are compared from two angles of visual effect and quantitative analysis.Amendatory IHS could improve spatial resolution and at meantime could stand out culture edge information and reinforce image's information amount,is more propitious to the recognition of rock type and the abstraction of tectonic information.
