摘要: 遥感影象的分析是土地资源研究的有效手段。而由重复摄影(或扫描)所取得的多时相(Multi temporal)遥感资料(或称多季节资料—Multi-seasonal data),给环境的动态监测及予报提供极为丰富的信息。遥感影象的多时相分析(又称时间鉴别分析—Time disoriminant analysis 或时间间隔遥感技术—Technique of Time-lapse remotesensing)则是研究环境动态变化的极好手段。

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.
