摘要: 利用2007—2008年MODIS/Terra陆表反射率数据提取的归一化植被指数(NDVI)、增强植被指数(EVI)及陆表水分指数(LSWI),分析了东北地区水稻、旱田、林地、湿地和水体5种不同下垫面在作物生长季的动态变化,同时结合水稻发育期观测数据,建立了东北地区一季稻面积提取模型,并制作了东北地区水稻种植面积分布图。以辽宁盘锦为试验区,利用ALOS数据提取结果对该模型进行了试验,提取精度达到89.5%,结果表明该方法可以较高精度进行大范围的一季稻种植面积提取。

Abstract: 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.
