论文:Dynamic  analysis  of  urban  spatial  expansion  and its determinants in Xiamen Island
    Most  of  the  world’s  cities  are  concentrated  in  coastal  areas.  As  a  special  geo-graphical component of the coastal system, island urban spatial expansion is the outcome of interactions  between  city  development  and  the  physical  environment.  This  paper  takes  Xia-men  Island,  located  in  Southeastern  China,  as  an  example  to  analyze  island  urban  spatial expansion  and  its  determinants  by  combining  an  analysis  of  the  literature  on  urban  devel-opment  policies,  urban  overall  plans,  population  growth  and  industrial  development,  with geographical  information  analysis  using  historical  maps  and  remote  sensing  photographs. Firstly,  we  reviewed  the  history  of  the  Xiamen  City  development  during  the  last  100  years, which  can  be  divided  into  four  periods:  the  embryonic  modern  city  and  early  development from 1908 to  1949; administrative boundary expansion and infrastructure development from 1950 to 1979; special economic zone construction and rapid urbanization from 1980 to 2003; and Bay City  construction since 2003. The dynamic changes to the coastline, island shape, built-up  area,  transportation,  administrative  division,  and  major  land  use  type  conversion which occurred during approximately the past 100 years were analyzed and the characteris-tics  of  the  island  urban  spatial  expansion  were  concluded:  early  expansion  from  a  central point,  followed  by  expansion  along  a  section  of  coastline,  and  expansion  from  the  coastline inland. Secondly, we discussed the potential determinants of island urban spatial expansion including  administrative  division  adjustment,  urban  master  planning  revision,  industrial  de-velopment,  topographical  factors,  coastal  area  reclamation,  transportation  expansion,  and population  growth.  Finally,  the  effects  of  each  potential  determinant  on  island  urban  spatial expansion  were  concluded.  Island  urban  spatial  expansion  is  the  result  of  a  synthesis  of natural and  socio-economic factors  which are not independent but  interacting.  Built-up area expansion  is  the  major  driver  of  island  land  cover  and  land  use  changes.  By  this  paper,  we hope to provide a scientific reference contributing to the rational understanding of island and coastal sustainable urbanization in China, and the world beyond.
