遥感技术估算草地面积的理论与实施

THE THFORY AND MPTHOD OF ESTIMATING AREA OF MEADOW BY REMOTE SFNSING TECHNIQUE

由于不同种类、不同生育阶段的牧草对电磁波具有不同的反射特性,因此我们可以在遥感影象上,进行目视判读或根据计算机兼容磁带用计算机进行解译以求得草地面积。

Different types of pastures and pastures in different developing stages have varied reflectivity to electromagnetic spectrums. So we can estimate the area of meadow on remote sensing images by naked-eye or by computers (through CCT ) .
