Remote Sensing of the Spatiotemporal Dynamics of Large Developed Land Areas in the Shore Areas of the Jin River of Fujian Province, SE China

Translated Abstract

In　this　paper,we　used　remote　sensing　technology　to　monitor　the　spatiotemporal　dynamics　of　large　devel-oped　land　areas　in　the　shore　areas　of　the　Jin　River　from　1987　to　2008.　The　area　is　a　fast　economic　development　re-gion,　and　therefore　has　witnessed　fast　urban　expansion　and　population　increase.　The　study　used　three　multitemporal　Landsat　images　of　1987,1996　,and　2008.　Firstly,the　newly　developed　normalized　difference　impervious　surface　in-dex　(NDISI)　was　used　to　extract　the　impervious　surface　areas　(ISAs)　from　the　used　Landsat　images,because　the　developed　area　is　dominated　by　the　ISAs.　And　then,　the　change　detection　technique　was　employed　to　reveal　the　change　of　the　large　developed　land　areas　from　1987　to　2008　in　the　studied　shore　areas.　The　result　shows　that　during　the　21　study　years　the　large　developed　land　area　has　significantly　increased,up　to　a　total　area　of　18　097　ha　of　new　developed　lands.　Most　of　them　occur　in　the　river　shore　areas　near　city　center,　especially　in　the　downstream　to　estu-ary　areas　of　the　river.　The　increased　large　developed　land　areas　were　mainly　converted　from　paddy　fields　and　fores-ted　lands.　Socio-economic　data　were　integrated　with　the　spatial　data　to　analyze　the　driving　forces　to　the　increase　of　the　large　developed　land　areas.　The　result　indicates　that　fast　economic　development,　urban　population　increase,　and　real　estate　development　were　the　three　major　deriving　forces　contributing　to　the　large　developed　land　area　increase.
