| 摘 要： | 基于Arcgis内置的VBA语言平台，实现一种渔业资源分布图批处理算法。该方法的主要特点是实现了对海量渔获数据自动批处理制图，平均绘图速度达到2s／幅，与手工绘图相比大大提高了工作效率。绘图结果清晰易读，可用于分析渔获物的数量分布和季节变化特征，如有多年统计资料，还可用于中心渔场预报研究，并可为渔业资源开发、利用和保护提供决策支持。

| Abstract: | A fishery resources distribution mapping batch processing algorithm was realized based on Arcgis VBA language.The mapping method can achieve the automatic batch processing mapping of massive fish catch data with an average mapping speed of sheet per 2 seconds,so greatly raises the working efficiency compared with the manual drawing.The plotted distribution maps are clear and readable,can be used for analyzing the number distribution and seasonal variation characteristics of fish catch,and if the multi-year statistic data are available,the distribution maps can be used for predicting the central fishing grounds,which can provide the decision-making support for the development,utilization and protection of fishery resources. |
