| 摘 要： | 以鄱阳湖1989～2009年10景秋季Landsat-TM影像为基础,对赣江主支口与饶河口交汇处三角洲和赣江南支口两处典型湿地进行了遥感解译,分析三峡工程运行后鄱阳湖典型湿地的演变趋势.结果表明:三峡工程蓄水运行之前,1989～2001年间鄱阳湖湿地草滩迅速蔓延,湿地正向演替趋势明显.距离湖口远近不同的湿地受三峡工程运...

| Abstract: | In the paper,the evolution law of the typical wetlands(the wetland near the confluence of Raohe River estuary and main branch estuary of the Ganjiang River,and Ganjiang southern-branch delta wetland) in the Poyang Lake wetland was studied by the classification of the Landsat-TM images during the period from 1991 to 2008.Results showed that the wetlands expanded the main water body of the Poyang Lake obviously.Furthermore the wetland was in a positive succession from 1989 to 2001 before the operation of the ... |
