Owing　to　the　development　of　the　social　economy,　the　geographical　environment　and　ocean　utilization　patterns　of　urban　coastal　zones　have　changed.　This　change,　in　turn,　has　influenced　the　socio-economic　development　of　urban　coastal　zones.　Based　on　the　Geographic　Information　System　technology,　the　area,　coastline　length,　and　shoreland　use　function　of　reclamation　areas　were　obtained　from　the　geographic　charts　(1954-2020)　and　remote　sensing　data　(1988-2017)　of　Quanzhou　Bay.　In　this　study,　we　analyzed　the　geomorphologic　change　process　and　the　relationship　between　land　use　patterns　and　economic　development　in　Quanzhou　Bay　from　the　perspectives　of　hydrodynamics,　sediments,　and　human　activity.　Our　results　indicated　that　over　the　past　70　years,　the　bay　area　has　reduced　by　21.5%.　The　length　of　the　coastline　decreased　from　208.36　km　in　1959　to　149.11　km　in　1988,　whereas　the　shape　index　of　the　bay　(SIB)　decreased　from　3.09　to　2.41　during　the　same　period.　Between　1988　and　2017,　the　coastline　increased　to　162.91　km,　causing　the　SIB　to　increase　to　2.72.　The　artificial　index　of　the　bay　increased　from　0.28　in　1959　to　0.90　in　2017.　The　intensity　of　bay　the　development　(IBD)　first　increased　from　0.27　in　1959　to　0.77　in　2006.　During　the　transition　to　a　more　modern　society　(2006　to　present),　the　IBD　slightly　decreased　to　0.73　in　2017.　Affected　by　human　activity,　the　transformation　of　the　reclaimed　land　in　Quanzhou　Bay　can　be　divided　into　four　stages　that　are　closely　linked　to　the　economic　development　in　the　region.　In　the　early　industrialization　period,　reclaimed　land　in　the　region　was　used　for　agricultural　production,　whereas　in　the　mid-industrialization　period,　it　was　gradually　transformed　into　a　combination　of　industrial　(29.8%)　and　agricultural　(56.1%)　lands.　In　the　later　period　of　industrialization,　the　reclaimed　land　was　gradually　converted　into　urban　industrial　and　port　lands.　Finally,　with　further　refinement　and　upgrading　of　economic　and　industrial　structures,　the　socio-economic　and　environmental　benefits　from　coastal　reclamation　projects　have　been　increasing,　whereas　the　proportion　of　economic　benefits　(in　the　total　benefits)　has　been　decreasing.　The　results　of　this　study　can　provide　decision-making　references　for　the　optimization　of　utilization　patterns　and　the　economic　development　of　reclamation　lands　in　coastal　areas.
