一、问题的提出本世纪60年代遥感技术问世以来,世界各国侧重于地球表面资源与环境的监测,对于海陆交互作用下的沿岸地带变化动态,仅作一般性的描述.作者从沿岸工程建设实际需要出发,力图从遥感图象信息中发掘新的解译标志和确立定量分析方法,以便使遥感技术应用在国民经济建设中. 近年来,我国沿海省市因改革开放的需要,纷纷兴建港口、电厂及码头,建港部门为着能在较短时间内对工程可行性问题进行宏观决策,在常规观测资料难以满足的情况下,不得不求助 First, the issue put forward Since the advent of 60 years of this century since the advent of remote sensing technology, countries around the world focus on monitoring the Earth’s surface resources and the environment, changes in coastal areas under land-sea interaction dynamics, only a general description of the author from the Coastal Engineering Construction In order to make the remote sensing technology applied in the national economy construction, in recent years, due to the need of reform and opening up, the coastal provinces and cities in our country have built the ports, Power plants and wharfs, Hong Kong Port Department to make a relatively short period of time on the project feasibility of macro-decision-making, in the conventional observation data is difficult to meet the circumstances, have to resort
