| 中文摘要: |
| 地质填图历史悠久,且一直被世界各国地质调查机构视为一项十分重要的工作。通过梳理世界主要国家地质填图的工作程度、填图重点和时间的演变等,总结世界主要国家地质填图的特点和趋势。绝大多数国家实现小比例尺地质编图工作的全境覆盖；大多数发达国家中比例尺填图覆盖程度较高,美国、澳大利亚以及英国、法国、西班牙等国家全覆盖,加拿大和俄罗斯覆盖2/3以上国土面积；世界各国大比例尺填图差别较大,欧洲国家地质填图覆盖率参差不齐,从不到10%(荷兰)到全部覆盖(英国、法国、西班牙等),美国覆盖2/3以上国土面积,加拿大和澳大利亚覆盖率相对较低。未来地质填图工作将以问题为导向,以综合地质填图为手段进行,三维地质填图越来越受到世界各国的广泛重视。 |
| 英文摘要: |
| Geological mapping has a long history and has been regarded as a very important task by the geological investigation agencies all over the world. By combing the work of geological mapping of major countries in the world,the focus of mapping and the evolution of time,the characteristics and trends of geological mapping in major countries in the world are summarized. Most countries implement the coverage of small-scale geological mapping; the coverage of scale mapping in most developed countries is quite high. The coverage in the United States,Australia,Britain,France,Spain and other countries is totally covered. Canada and Russia cover 2/3 Above the size of the land area; large scale mapping around the world vary greatly,the coverage of geological mapping in European countries is uneven,from less than 10% (Netherlands) to full coverage (Britain,France,Spain,etc.) The above land area,Canada and Australia,the coverage rate is relatively low. Geological mapping work in the future will be problem-oriented,with integrated geological mapping as a means of three-dimensional geological mapping more and more attention by countries in the world. |
