摘要
为了快速录入和分析渔获信息,了解最新的渔业资源动态,以智利竹筴鱼Trachurus murphyi渔业为例设计了一种渔获量数据录入和分析的模块。该模块利用OLE控件读取Excel数据,通过数据库管理与分析数据,选用MapObjects功能组件进行二次开发,把数据转换为矢量点数据,制成专题图,最后打包成DLL(动态链接库)发布。录入与分析模块的使用,提高了数据录入速度,降低了出错概率,提供了多种方法分析渔获量数据,该模块已成为大洋渔业信息服务系统的重要组成部分。
A fishing data entry and analysis module for Chilean jack mackerel was designed and implemented in order to quick entry and analysis of fishing production information on the latest dynamic fishery resources by OLE technology for read Excel data.Data management and analysis was based on database,Data was converted into vector data and made thematic maps by MapObjects as secondary development components,and finally Module was packaged into DLL dynamic link library.The data entry speed was improved and the probability of error reduced in the use of the input and analysis module as an important part of ocean fisheries information service system which provided a variety of methods to analyze fishing yield data.
