航空象片材积表的特点,是把象片判读的因子和地面实测材积联系起来了。根据这一特点,在森林调查中应用象片材积法估计林分的蓄积量,可以大幅度地减少外业工作量和提高森林调查的速度。本文根据1983年东北林学院帽儿山实验林场森林经理复查的地面实测资料和1982年6月摄影的1∶10,000比例尺全色航空象片,来编制帽儿山地区航空象片林分材积表。
The features of the aerial photogrammetry table are to relate the factors of the photographic interpretation to the actual measured volume of the ground. According to this feature, estimating the stock volume of the forest in the forest survey using the slice volume method can greatly reduce the workload of the field and speed up the forest investigation. In this paper, according to the ground survey data of forest managers in Maoershan Experimental Forest Farm of Northeast Forestry University in 1983 and 1: 10,000 scale panchromatic aerial photographs taken in June 1982, we compiled the stand volume table of forest photos in Maoershan area.
