基于多时相遥感的泉州湾滨海湿地变化监测

摘要

This paper's research area is coastal wetland and its surrounding areas of Quanzhou bay and employs the ENVI5.1 software for five times in 1990、2000、 2005、2010 and 2015 remote sensing image of the research area, which was processed by image preprocessing.Then, the ARCGIS10.2 software was employed to make map, the result was four dynamic change maps of the research area.Dynamic change of the research area was constracted and analyzed in this end.The result shows that Spartina alterniflora has obvious phenomenon of invasion on the research areas.The sandy beach , mangrove and tidal flat, decreased in the first and recover in the later.%本文所研究的地区为泉州湾滨海湿地及其周边地区,运用ENVI5.1软件对1990年、2000年、2005年、2010年、2015年的泉州湾滨海湿地及其周边地区遥感图像进行图像预处理后,运用ArcGIS10.2软件对处理好的遥感影像进行地图的制作,得到四幅研究区动态变化专题图,最后对比分析泉州湾滨海湿地及其周边地区的动态变化情况.结果显示米草地对泉州湾滨海湿地及其周边地区有明显的入侵现象.沙滩、红树林和滩涂的面积在早期不断缩减,三者的面积缩减在后期略有减缓.
