摘要： 为了实现黑龙江省东部地区水稻种植信息遥感监测的业务化，通过采用实地调查、ISODATA非监督分类、遥感数据融合和光谱耦合等方法，研究提取研究区水稻种植分布的方法，并进行面积推算。结果表明，2012年黑龙江省东部地区水稻种植面积为15389.01 km2，主要集中在佳木斯、双鸭山和鸡西地区，分类精度达89.19%。该方法可为区域水田空间分布信息提取提供借鉴。

Abstract: The objective of this research was to evaluate the applicability of remote sensing data in 2012 for large-area crop mapping over the northern Heilongjiang Province. Rice area and its spatial distribution was obtained based on ground truth data, ISODATA unsupervised classification, data fusion technique and spectral matching technique. We found that rice area in 2012 was 15389.01 km2, and it mainly distributed in Jiamusi, Shuangyashan and Jixi County. The classification accuracy was 89.19%. This method could provide some reference for extracting spatial information of regional paddy fields.
