| 摘 要： | 海岸带是重要海陆过渡带地貌单元与区域,兼受海陆动力双重作用与影响,包括不同类型的沉积相,经历复杂的动力沉积、地貌演变及灾变过程。海岸带调查涉及学科交叉融合,调查要素相对独立与内容多学科交叉并存。我国曾分别于1960年、1981年和2003年组织开展过全国海岸带综合调查工作,调查获取了大量丰硕成果。当前海岸带调查与研究过程中亦暴露出一些亟需突破问题,包括:1)海岸带存在大范围"盲区",浅水易陷、礁石养殖等区域难以到达,成为海岸带数据"空白区"、调查"禁区";2)我国海岸带观测平台数量少、分布零散,未形成综合有效观测网,导致长时间序列、多源准同步调查数据缺乏,难以准确把握海岸带变化规律,破解资源环境有关问题;3)海岸带数据获取智能化程度低,严重阻碍制约有关对策及时有效性;4)海岸带不同学科协同调查、交叉融合研究模式尚未建立,不能及时发现海岸带科学问题。今后海岸带调查将在海岸带高分辨率过程数据、全覆盖无死角实时动态数据获取技术,长时间序列综合数据采集平台建设,陆海空全天候立体化数据采集传输及快速智能决策,以及海岸带多学科交叉攻关研究等方面取得突破。

| Abstract: | The coastal zone is an important region and geomorphic unit in the sea-land transition zone and has been subjected to the dual action and influence of land and sea dynamics. It contains different types of sedimentary facies and has experienced complex processes of dynamic deposition, geomorphological evolution and catastrophe. The coastal survey involves multi-disciplinary cross amalgamation, relatively independent surveying elements and multi-disciplinary content coexistence. Nationwide comprehensive surveys coastal zone were carried out in China respectively in 1960, 1983 and 2003 and a large number of fruitful results have been obtained. However, problems which are badly need of breaking through in the coastal survey and research have also been revealed. They are 1) In the coastal zone a large range of “blind areas” where no survey has been carried out are present and some inaccessible areas such as shallow and easily sinking areas, reef and mariculture areas, and so on, have become a data “blank area” and/or a surveying “forbidden area”;2) In China, the coastal-zone observation platforms are few and in a scattered distribution and a comprehensive and effective observation network has not yet been formed, leading to the lack of long-time series and multi-source quasi-synchronous survey data and making it difficult to grasp the change law of coastal zone accurately and solve the problems related to resources and environment;3) The intelligence level of the acquisition of coastal zone data is so low that the timeliness and effectiveness of the relevant countermeasures are seriously restricted;4)The model for collaborative survey and cross-fusion research of different disciplines in the coastal zone field has not yet been established so that the scientific problems on coastal zones could not be found timely. It is therefore suggested that the future investigations of coastal zone should make breakthroughs in the acquisition technology of high-resolution process data and full-coverage and real-time dynamic data, the construction of long time series and comprehensive data acquisition platform, the acquisition and transmission of all-weather data of land, sea and air and the fast intelligent decision, and the interdisciplinary and collaborative study of coastal zone. |
