我国是一个海洋大国,拥有一万八千多公里海岸线,六千五百多个岛屿,管辖海域广阔,海洋资源极为丰富,蕴藏着巨大的开发潜力,在国民经济的总体发展中,海洋的开发和利用具有重要的现实意义和深远的战略意义,向海洋索取财富,变海洋资源优势为经济优势已是人类的共识。因此,把海洋开发提到重要议事日程上来,已刻不容缓。为此,山东省于1990年10月至1992年3月,组织1800多人,其中科技人员1406人的海洋现状调查组,对本省海洋资源进行了一次大规模的调查摸底。为了得到准确的海岛数量、位置、面积、岸线长度等基础数据,调查中采用了地面登岛调查和飞机航空遥感慨查相结合的方式,保证了调查数据的精度,调查 China is a large marine country with more than 18,000 kilometers of coastline and 6,500 islands. It has a vast sea area under control and an extremely rich marine resources. It has great potential for development. In the overall development of the national economy, the development of the oceans It is a consensus of humankind to make economic advantages by resorting to the means of obtaining wealth from the oceans and turning the advantage of the marine resources into reality with far-reaching strategic significance and significance. Therefore, it is imperative to refer to the important agenda of ocean development. To this end, Shandong Province from October 1990 to March 1992, more than 1,800 organizations, including scientific and technological personnel of the 1406 marine state investigation team conducted a large-scale survey of marine resources in the province thoroughly. In order to get the accurate data such as the number of islands, the location, the area and the length of coastlines, the method of combination of ground-based island investigation and aviation aviation remote sensing was adopted in the survey to ensure the accuracy of the survey data and investigate
