Abstract：

This　paper　investigates　the　potential　of　ENVISAT　ASAR　data　for　rice　crop　mapping　in　Fujian　Province,　where　the　agricultural　fields　are　cracked.　The　ASAR　data　with　VV　and　HH　polarization　acquired　between　two　acquisition　dates　over　the　whole　rice　growth　season　were　used.　The　study　area　is　located　in　Fuzhou,　Fujian　province,　China.　After　analysis　the　backscatters　of　VV　and　HH　polarization　in　the　two　dates　during　each　rice　growth　season,　a　backscatter　change　index　(BSCI)　combining　the　VV　and　HH　backscatters　of　the　two　dates　was　calculated.　The　BSCI　value　of　rice　field　is　much　higher　than　those　of　other　land　covers.　A　method　using　the　BSCI　was　proposed,　which　was　a　fast　rice　crop　mapping　method.　The　accuracy　of　rice　field　mapping　in　three　rice　seasons　was　all　promising　high.
