| 摘 要： | 近年来，鄱阳湖枯水期水位连创新低，湖区湿地环境有退化的趋势。为了分析鄱阳湖湿地不同类型土地在不同季节的变化情况，通过收集2003~2009年间60多幅景湖区MODIS、Landsat TM清晰无云遥感图片，对湿地植被变化情况进行了监测分析，提出了湿地植被地类的识别和分类计算方法，计算出2009年各月鄱阳湖区植被面积，首次重点分析了2003~2009年汛期过后的秋冬季（10~12月份）湖区湿地植被多年变化规律，并对湖区11月份植被群落进行了分类和初步识别，分析出各群落的变化趋势及其与水位的关系。

| Abstract: | In recent years,the water level of Poyang Lake continues to go down to the lowest value in history in dry season successively and the environment of wetland trends to degrade.In order to analyze the wetland vegetation change in different seasons,through collecting more than 60 clear and cloud-free images of MODIS and Landsat TM remote sensing data from 2003 to 2009,the analysis on wetland vegetation changes is conducted and the method to identify and classify wetland vegetation is presented.The vegetation a... |
