据报导,截止1977年,苏联1:20万区测已完成全国面积的85％,1:5万完成了全国面积的21％。预计,1:20万到1990年将全部完成;1:5万到1985年将完成30.5％。近年来,苏联广泛采用了高效率的组合地质测量方法,其成本与逐幅地质测量相比,1:20万每平方公里低1/3,1:5万每平方公里低20％。航空摄影地质测量也得到了广泛的 According to the report, as of 1977, the 1: 200,000 area in the Soviet Union had completed 85% of the country’s area and 1: 50,000 completed 21% of the country’s area. It is estimated that 1: 200,000 to 1990 will be fully completed; 1: 50,000 to 30.5% by 1985. In recent years, the Soviet Union has adopted a wide range of highly efficient combined geologic surveying methods at a cost that is 1/3 down 1: 200,000 per square kilometer and 20% lower than 1: 50,000 per square kilometer compared to the geological survey by field. Aerial photographic geological surveys have also been extensive
