| 摘 要： | 中亚干旱区内陆湖泊的湖面变化反映了气候波动和人类活动对流域水文过程的影响.本文以中亚干旱区平原区尾闾湖泊、吞吐湖泊和高山湖泊三类典型内陆湖泊为研究对象,利用1975-2007年Landsat遥感影像,基于归一化水体指数提取湖泊水域边界信息,分析近30年来内陆湖泊湖面变化特征.结果表明,近30年来,研究区内有超过一半的内...

| Abstract: | Inland lakes are major surface water resource in arid regions of Central Asia,the area changes of these lakes were the results of climate changes and human activities.The paper aimed to discuss lake area changes and their mechanism with three different types of inland lakes in Central Asia.Firstly,four time period Landsat MSS/TM/ETM+ imagery were used to delineate water boundary information based on NDWI(Normalized Difference Water Index) threshold segmentation method,then lake area variations were analyzed... |
