基于MapObjects的稻水象甲疫情呈报地理信息系统

【背景】稻水象甲是我国最具危害性的外来入侵物种之一，自1996年传人福建省以来，对当地农民增产、增收及粮食安全生产构成了极大威胁。【方法】依据1996～2008年福建省稻水象甲发生面积数据，结合GIS技术和数据库管理技术，以VisualBasic6．0为开发语言，Access2003为Geodatabase空间数据库、MapObjects2．0为地图开发组件，开发了福建省稻水象甲疫情呈报系统。【结果】本系统实现了稻水象甲疫情实时呈报、基于GIS地理分布查询、专题地图制作等功能。专题地图制作和可扩展性是本系统的两大特点，用户不需要专业的GIS和计算机知识，就可以生成一套适合自己的植物疫情呈报系统，为农业病虫害防治工作提供疫情呈报与GIS查询服务。【结论与意义】本系统为稻水象甲的实时监测、防控工作提供了管理工具；界面友好、操作简单且可扩展性良好，便于基层普及应用。

Distribution of rice water weevil Management Information System base on MapObjects

Background ] Lissorhoptrus oryzophilus Kuschel （rice water weevil）, an invasive exotic species to China, causes serious economic losses to the local agriculture. Method] Data on rice water weevil distribution were collected between 1996 and 2008 in Fujian, using GIS, Geodatabase, and ActiveX as MapObjects 2.0 and used to develop an information system with, which was based on Visual Basic 6.0 language. Result ] The system included the functions of data of damaging uploading, management, searching ahd drawing of theme. The drawing of theme and scalability were the two main characteristics of the system. A suitable plant epi- demic reporting system could be generated so as to provide epidemic reporting and GIS inquiry service for the prevention and control of agricultural pests and diseases without professional GIS and computer knowledge. Conclusion and significance ] The system pro- vides software management tools for real-time monitoring, prevention and control of rice water weevil. This system has a friendly in- terface, which will improve rice water weevil pest control.
