摘  要:
利用美国Landsat-7的ETM+数据作为主要数据源,采用ER MAPPER 7.0专用图像处理软件制作了湖南省四水流域和洞庭湖水域解译图,获取了湖南省水资源的空间分布信息。结果表明:湘、资、沅、澧四水和洞庭湖水域面积总和为6224.72km2,其中洞庭湖水域面积为2710.13km2,湘江省内长度为722.07km,资水省内长度为687.31km,沅水省内长度为597.35km,澧水省内长度为423.57km,说明利用遥感技术调查湖南省水资源具有快速、准确和高效的特点。

摘  要:
This paper utilizes the ETM+ data obtained from Landsat-7 of American as the primary data and uses the software of ER MAPPER 7.0 that specialized in image managed to make four rivers and Dongting Lake interpretation image in Hunan province and attains the spatial distribution information of water resources in Hunan province.The result showed that the summation water areas of Xiang-Zi-Yuan-Li four rivers and Dongting Lake is 6224.72km2,Dongting Lake water area is 2710.13km2,Xiangjiang river length is 722.07km,Zi river length is 687.31km,Yuan river length is 597.35km,Li river length is 423.57km.It indicates that utilizing the remote sensing technology to survey the water resources of Hunan province,which has fast,accurate and high effective characteristics.
