海洋渔业资源地理信息系统应用的时空问题

Spatio temporal problems of geographic information system in marine fishery

利用GIS描述海洋渔业资源时空动态变化,建立渔业资源评估模型和预测模型,是当前渔业现代化的重要趋势之一。在回顾海洋渔业地理信息系统(MFGIS)发展的基础上,分析了其应用实例及不足,重点探讨了MFGIS所面临的时空数据获取与标准、时空数据表达、时空动态尺度和时空统计与分析模型四方面的技术内涵,并讨论了解决途径。

In marine fisheries, it is very important to understand and grasp the spatio-temporal nature. Geographical Information System (GIS) has been applied to describe or forecast the dynamic trend of resources or to set up evaluation model, which is one of high technologies in modern marine fisheries. Based on the review of the development of marine fishery GIS (MFGIS), four spatio-temporal problems it occurred were discussed, and the possible resolutions were prospected.
