There is agreat dealofliterature onurban construction land use focuses on expansionpattern,mechanism,growth management,reasonable land scale, and application of RS and GIS the basis ofexistingstudies,this dissertation uses Fuzhou city as acase study tOunderstand analysis on urbanconstructionlandexpansion lays thefoundation for theresearch on urbanspatial structure andformation evolution inthe on thedataofurban constructionland extractedfromTM remote sensing images in 988,2000 and ALOS remote sensing image in2008,晰m other datasuch asmaps,statistical datainFuzhou, thisarticleconducts ananalysis on thetemporaland spatialcharacteristicsofurban construction landexpansion in thepast 20years,through studying theurban construction land expansion quantity,morphologypattem,driving forces,existing problems and resultshows that:mosturban constructionland locatein也e 0km buffer area tothecitycenter,expansion gradient indexofurban constructionland is biggest inthe3km bufferarea tothecity centerand decreaseprogressively toedge, expansion intensity indexofurban constructionland isbiggest inthe4—5l(111and6~7 buffer area tothecity center and decrease progressively to edge construction landmainly locates innorth,east andsouth,expansion intensity indexand expansion inte
