遵照毛主席“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上”的伟大教导,1973年我队进行了航空象片判读和实测蓄积的回归试验。结果表明,用该方法所得分区的资源精度都在90%以上,与通常的分层抽样相比,效率约提高8倍,成本降低70%左右。 In accordance with Chairman Mao’s great teaching that “mankind always develops continuously within the scope of the struggle for production and science and experiments, and nature will always develop ceaselessly and will never stop at the same level.” In 1973, our team carried out aerial photography Interpretation and testing of the cumulative regression test. The results show that the accuracy of the resource obtained by this method is above 90%. Compared with the usual stratified sampling, the efficiency is improved about 8 times and the cost is reduced by about 70%.
