| 摘 要： | 为探讨"纳尔吉斯(Nargis)"飓风对缅甸伊洛瓦底江三角洲地区的影响,利用该地区的遥感数据,用ISODATA非监督分类和贝叶斯最大似然监督分类方法对研究区土地覆盖进行分类,得到了纳尔吉斯飓风前后缅甸伊洛瓦底江三角洲地区土地覆盖的定量变化,并对纳尔吉斯飓风灾害与红树林面积和密度的关系进行了定量研究.结果表明,红树林面积越大,种植密度越高,对减小飓风灾害的作用越大.

| Abstract: | In order to investigate the effects of the Nargis hurricane on the Ayeyarwady Delta in Myanmar,the ISODATA(iterative self-organizing data analysis techniques algorithm) unsupervised classification method and the Bayesian maximum-likelihood supervised-classification method were used to classify the land cover of the study area based on Myanmar ALOS/AVNIR-2 remote sensing data,and the quantitative changes of land cover in the Ayeyarwady Delta before and after the Nargis hurricane were obtained.In addition,the... |
