| 摘 要： | 利用2004-2005年MODIS 16 d合成的NDVI最大值植被指数数据，基于NDVI光谱突变方法对山西省运城地区冬小麦种植面积进行提取。通过分析得出：2005年5-6月（2005161～2005129）提取的冬小麦面积与实测面积相关性最高，估测的冬小麦面积与实测面积的误差最小，准确性最高。

| Abstract: | Using the maximum NDVI from 16 days of MODIS data from 2004 to 2005,on the basis of NDVI spectral region mutation methods,the winter wheat planting area in Yuncheng in Shanxi Province were extracted.The analysis results showed that there was the highest relevance between the extracted area and measured area of winter wheat from May of 2005 to June of 2006.There was the least error between estimated area and measured area of winter wheat.The accuracy was the highest during this period. |
