利用航天遥感资料进行森林资源调查的研究

本文着重阐述了研究应用陆地卫星 MSS 数据进行森林调查的技术流程,评价调查精度并比较外业工作量和生产成本。实验研究表明,利用陆地卫星多光谱扫描数据的计算机分析,可以计算林区各类土地面积和森林蓄积量,绘制森林分布图和蓄积量分布图。同时具有效率高、成本低和节省地面工作量的优点。在我国北方林区,特别是交通不便、尚未开发的林区有应用潜力。

A STUDY ON APPLICATION OF SPACE REMOTE SENSING DATA TO FOREST INVENTORY

This paper deals with the technological process of applying Landsat MSS data to forest inventory at the forest bureau, evaluates the accuracy of the Survey and Compares the field work load and production cost with traditional methods. The study done at Qiao Shan Forest Bureau reveals that by means of computer analysis of Landsat MSS data we can easily estimate the areas of varied land types and timber volumes, and draw the forest map and timber volume distribution map. Moreover, the techniques is possessed of the following advantages: high efficiency, low cost and less field workdays. In the forest zone in North China, especially in that part of forest where it is hard of access and has not yet been opened up. The techniques will be very useful.
