中小比例尺航片森林蓄积量的遥感判读研究

Study on Remote Sensing Interpretation of Forest Volume in Middle and Small Scale Aviation Image

研究了中小比例尺航片在森林蓄积量判读上的应用,结果表明:可以根据航片上影像灰度的平均值来进行树种的判别;利用灰度标准偏差进行林分蓄积量的估测,其拟合误差不足5%,满足林业生产实践的精度要求。填补了中小比例尺森林蓄积量判读的空白,是建立森林蓄积量判读的不同比例尺、不同遥感来源立体判读体系的重要补充,具有十分重要的现实意义。

The application of middle and small scale aviation image in the remote sensing interpretation of forest volume are studied,the results indicate that tree species can be distinguished according to the average of the image gray;and forest volume can be estimated according to gray standard deviation,its fitting error is less than 5% and its precision satisfy the production practice needs.The study fill in the blanks of the remote sensing interpretation of forest volume in middle and small scale aviation image,is an important supplement of establishing a stereo remote sensing interpretation of forest volume system in different scale,different remote sensing source remote sensing image,and has very important practical significance.
