| 摘 要： | 利用1999/2000年和2006/2007年2个不同时相的遥感影像对福建省沿海水域的互花米草进行解译提取,并结合地理信息数据和社会统计数据进行变化分析。研究表明:基于专家决策树的福建省互花米草信息提取法具有较高的解译精度,动态监测结果显示,7a来福建沿海水域互花米草蔓延迅速,已侵占了大片的养殖水域和滩涂资源,研究旨在为引起有关部门的高度重视并采取必要的治理措施提供理论依据。

| Abstract: | The information of inshore Spartina alterniflora was extracted by using the Landsat images of 1999/2000 and 2006/2007 in Fujian,and the dynamical change of Spartina alterniflora was analyzed by combination with the GIS data and statistics during the past seven years.The results showed that the decision tree classifier was well applied to extract the information of Spartina alterniflora from the remote sensing images and acquire higher classification precision.In addition,the dynamic monitoring results revea... |
