Abstract: The multitemporal analysis of remote sensing images is to compare and discriminate the differetiation in temporal images of various time and environment by means of spetific technique for revealing the process and tendency of environment revolution.This paper takes Xishui county of Hubei province as an example to expound its application on land studies. The technical methods of multitemporal analysis generally Can fall into the following Categories:1.Optic composition of two or multi-seasonal images.2. Ratio method.The normalized density ratio of MSS5 and MSS7 can better express season change of vegetation.3.Amplifying method of computer-optics.In the study,the visual interpretation still had been adopted as a principal method, supplementing with the optic composition.The results,distinguging and mapping various land types as well as expounding the dynamic changes in future in the test area have been reached.
