| 摘 要： | 滩涂面积量算是滩涂资源调查中的一项重要工作内容，其结果数据是调查成果的总体表现与直观反映，为滩涂围垦规划调整、围垦工程合理建设提供了数据支持。通过对标准图幅内的滩涂分布类型进行归纳整理，提出了一种自下而上基于标准图幅的滩涂面积量算方法：首先利用标准图幅内的等深线、岸线实现滩涂面的快速生成，其次计算滩涂面包含的水深点平均高程值判断滩涂类型，最后根据不同条件对滩涂面积分类量算统计。在2011年浙江省滩涂资源调查中的实践证明，该方法简单易用，具有一定应用价值。

| Abstract: | Tidal flat area calculation is very important in the tidal flat resource investigation .The result data directly reflects the distri-bution of tidal flat resource in Zhejiang , and provides support for reclamation plan adjustment and projects construction .Through sum-marizing the tidal flat distribution types , a method of tidal flat area calculation based on bottom -up standard maps was presented . Firstly , fast generated tidal flat polygons with isobaths and shorelines in standard map .Secondly , judged the tidal flat type by calculat-ing average elevation values of underwater points .Finally, classified and counted statistics under different conditions .It was used and verified in Zhejiang tidal flat resource investigation . |
