Extraction of single cropping rice area in Northeast China based on multi-temporal MODIS data

By using the 2007-2008 MODIS/Terra dataset of normalized difference vegetation index(NDVI),enhanced vegetation index(EVI),and land surface water index(LSWI),this paper analyzed the dynamic variations of five underlying surfaces(rice field,upland field,forestland,wetland,and water body) in Northeast China during growth season.In combination with the observed data during rice growth perod,a model for the extraction of rice planting area in the region was established,and the distribution of the rice planting area was given.The model was validated with the ALOS data of Panjin City,Liaoning Province,and the precision reached to 89.5%,suggesting that the model could be used for the extraction of rice planting area in large scale.
