Regular Method of Estimating Cultivated Rice Area by Using EOS/MODIS Data

以江西省2005年早稻种植面积卫星遥感监测为例，提出了应用EOS／MODIS的1～7通道和NDVI值作为资料源，以实地考察采样点为参考点，目视解译出均匀分布的样点资料，然后根据样点资料的7通道和NDVI值特性，判定整幅图的所有格点是否属于早稻种植区的业务化运行方法。还对监测效果进行了初步分析，提出了可提高监测精度的可业务化技术方法。

Taking artificial satellite remote - sensing monitoring of cultivated early rice area in 2005 in Jiangxi province as an example, the author proposed the regular method of estimating the cultivated early rice area, including taking actual sampling spots as reference spots, interpreting out the sampling spots in uniform distribution by sight, then determining the all grid spots of entire chart whether belonged to early rice cultivation region according to the sampling spot information in the channel 7 of EOS/MODIS data and the property of NDVI value. In addition, the monitoring effect of the method was preliminarily analyzed, and the improved regular method with higher monitoring accuracy was put forward.
