摘　　要：海岸线是沿海地区海洋经济发展的空间载体,具有重要的生态功能和资源价值。本文通过对海岸线的内涵与定义进行系统分析,结合管理实践要求,建立了基于陆海统筹的海岸线分类体系。梳理了海岸线划定的原则,通过分析不同岸段的属性特征、管理需求等因素,提出了以下几种划定方法:自然岸线采用痕迹线法、多年平均大潮潮位法以及综合研判法;人工岸线采用综合研判法;河口岸线采用特征排序法;生态恢复岸线采用指标量化打分法。该研究可为我国海岸线保护与利用管理提供参考。As a significant spatial carrier for marine economy developments on coastal areas, the coastline possesses extremely important ecological functions and resource values. Based on the comprehensive analyses of coastline implications and definitions, this paper establishes a sea-land coordinated coastline classification system with respect to the requirements of corresponding managements and practical applications. In addition,by taking into account various coastline delimitation principles, and considering diverse factors(namely,attribute characteristics, administrative specifications and so on) of coastline segments, this paper proposes a series of efficient delimitation methods for different types of coastlines, for example, mark line-based algorithm for natural coastlines, mean water spring-based method as well as comprehensive assessment-based approach,comprehensive assessment-based technique for artificial coastlines, feature sorting-based algorithm for estuarine coastlines, index quantification scoring-based way for restored ecological coastlines and so forth,which are beneficial to the national coastlines in terms of protections, utilizations and managements.
