福建围填海及其对海洋环境影响的遥感初探

Preliminary application of remote sensing:reclamation on Fujian coast and its effects on marine environment

把遥感技术应用于海岸带现状的动态研究和遥感海洋环境反演是当前遥感应用的热点之一。文章主要利用美国资源卫星专题扫描仪(thematic mapper,TM)遥感影像研究福建围填海状况及大陆海岸线的变化,通过ENVI、ArcGIS软件对研究区遥感影像进行处理,实现海岸线的自动提取、土地分类,以监测福建围填海的动态变化。通过相同季节的中分辨率成像光谱仪(moderate-resolution imaging spectroradiometer,MODIS)遥感影像反演福建海域海水表层温度及叶绿素浓度等海洋参数来了解围填海对海洋环境的可能影响。

It is one of the current hot topics in application of remote sensing to use remote sensing techniques in coastal dynamics research and marine environment retrieval.We retrieved the changes of Fujian reclamation and the mainland coastline from thematic mapper（TM） remote sensing image,which realizes coastline automatic extraction,land classification and marine environmental parameters retrieval using ENVI and ArcGIS softwares to process regional remote sensing images.We also retrieved sea surface temperature（SST） and chlorophyll concentration from moderate-resolution imaging spectroradiometer（MODIS） ocean color remote sensing images in the same season and area,to discuss the reclamation’s potential effects on marine environment.
