| 摘 要： | 根据GIS原理和功能,探讨捕捞作业海域内生产渔船动态变化,可直接服务于捕捞生产和安全管理。本文应用舟山市海洋与渔业局AIS系统,在一定时间内采集与分析研究海域内虾拖网渔船坐标位置和数量资料。结合研究海域形状和我国捕捞渔区划分标准,对研究海域进行分区处理。利用Arc GIS软件,处理各分区内虾拖网渔船变化数据,制作浙江省虾拖网渔船作业分布图,参考人口重心模型计算虾拖网渔船作业分布重心,分析目标海域虾拖网渔船作业短期分布变化,为虾类资源调查、渔业生产安全保障以及渔船管理提供理论依据。

| Abstract: | Based on the principles and functions of GIS, the dynamic changes of production shrimp trawlers in the research waters were explored and its can serve the fishing production and security management directly. In this paper, the coordinate location and quantity of shrimp trawlers in the waters within a certain time were collected and analyzed according the AIS system. The waters have been divided into some parts based on the shape of the waters and division standard of fishing areas. Application the software analysis of ArcGIS, the partition number of shrimp trawlers in Zhejiang province were obtained, meanwhile based on the number of boats within the partition for classification and grading, the shrimp trawlers pointer centre in the sea area were calculated, and the changes in distribution of shrimp trawlers in the short term were discussed. |
