Abstract:
It has been more and more noticed by people that the urban expansion and change impact urban environments.Take Fuzhou City as a demonstration case,the RVI,DVI,NDVI and VCI,which indicate urban vegetation coverage change,are calculated every year by using MODIS data of EOS satellite during 2001—2005.With the help of GIS and GPS,the interannual dynamic changes of different vegetation index in Fuzhou are researched,and urban expansion and change in Fuzhou are monitored based on MODIS data.At the same time,the research results are analyzed with socio-economic data.The results show that the urban expansion areas in Fuzhou have increased by about 29km2 between 2001 and 2005,about 7.3km2 each year.The above results are credible in comparison with the real situation.The urban expansion areas can be monitored correctly by using MODIS data.
