摘要/Abstract

摘要： 利用多期地形图和遥感影像数据(Landsat TM/ETM)，在地理信息系统平台上获取长江中下游主要湖泊的水域面积时空变化，并对其进行了研究分析.结果表明，长江中下游主要湖泊的总水域面积，在1971-1988年减少了2 544.51km² ,1988-2000年减少了1 151.97km².湖泊水域面积的减少是自然因素和人类活动综合作用的结果，围湖利用是湖泊水域面积减少的主要原因.

Abstract: Spatial and temporal data of the major lake surface aera change in the mid-lower reaches of the Yangtze River were obtained and analyzed on the platform of geographical information system (GIS) by using digital topography maps and satellite remote sensing images(Landsat TM/ETM) in different periods of time. The results showed that： the total lake surface area in the mid-lower reaches of the Yangtze River reduced about2 544.51km2 from 1971 to 1988 ,and 1 151.97km2 from 1988 to 2000. This should due to both nature factors and human activity ,but the major factor was lake reclamation.

Key words: lake surface area, MNDWI, the mid-lower reaches of the Yangtze River, lake surface area, MNDWI
