Supervised and unsupervised image classification were applied to the study area TM image and t o the paddy field TM image. And the early rice areas were calculated by each met hod. Using the proposed methodology improved the quantitative accuracy of ear ly rice area estimated up to 93.98%, whereas it was 82.83%when image classific ation was used only. The extracted information from the c lassification is belonging to the early rice and not to any other vegetation. Si nce the GIS database is available, the method is easily applicable to any new RS images.

不同方法比较结果表明：非监督分类法不能用于提取丘陵山区的水稻种植面积；只用TM资料估算龙游县早稻面积，与统计数据相比，平行六面体分类法、最大似然分类法精度分别达到82.83%和59.95%；而用GIS 与TM资料集成技术对水田分布图进行分类估算早稻面积，平行六面体分类法、最大似然分类法的估算精度分别达到93.98%和60.65%，所以利用平行六面体分类法对南方丘陵山地早稻种植面积估算是可行的。
