本文介绍在航空象片上进行树高和冠幅的量测,通过其比值以判读森林立地指数。这种方法不仅可以提高立地指数测定的工作效率,而且还可以与立地制图相结合,充分地发挥了航空遥感信息的潜力。
This article describes the measurement of tree height and crown width on aerial photographs, by which the ratio of forest height indices can be interpreted. This approach not only enhances the productivity of the site index determination, but also combines with site mapping to fully exploit the potential of aeronautical remote sensing information.
