世界人口生活在沿海地区的约占60％,人口对沿海资源所造成的压力与日俱增。在热带发展中国家,海岸带管理作为资源持续开发利用的一种手段,人们越来越迫切地感觉到综合管理手段的必要性。人们普遍认为,资源评价是沿海地区信息通畅管理的基本先决条件。遥感技术由于其对地球大范围观测的能力,因而是资源评价的重要工具,但遥感技术的观测能 About 60% of the world’s population lives in coastal areas and the population is under increasing pressure to coastal resources. In tropical developing countries, as a means of continuous development and utilization of resources, coastal zone management is more and more urgently felt the need of integrated management tools. It is generally accepted that resource assessment is a basic prerequisite for the smooth management of information in coastal areas. Remote sensing technology is an important tool for resource assessment because of its ability to observe a large area of ​​the Earth, but remote sensing technology can
