| 摘 要： | 目的]利用不同时序EOS/MODIS-NDVI数据计算河南省冬小麦面积。方法]对MODIS图像数据进行转换、地理较正和波段组合等处理后,从而获得不同时间序列的归一化植被指数(Normal Difference Vegetation Index,NDVI),然后在地面光谱测量基础上进行监督分类,得出河南省2005年小麦种植面积。结果]该法所测河南冬小麦像元总数92 208个,种植面积为576万hm2,与统计部门统计数据相比,误差为9.66%。结论]该研究为冬小麦种植面积监测提供了新途径。

| Abstract: | Objective] Calculation of winter wheat acreage in Henan Province using EOS/MODIS-NDVI data at different time sequences.Method] After process of EOS/MODIS images,geographical adjustment,wave band combination,normal difference vegetation index(NDVI) was obtained.Based on the wide spectrum measurement,the processed data were supervisedly classified,thus the acreage of winter wheat in Henan Province in 2005 was acquired.Result] Total 92 208 pixels were observed for the winter wheat in Henan Province,and the plantation acreage was 5 760 thousand hm2.Compared with the data from statistical department,the error of this method was about 9.66%.Conclusion] The method introduced in the present study could be applied in monitoring winter wheat acreage. |
