摘　　要：农作物疫情地理信息系统是基于2001、2002年全国农作物有害生物疫情普查开发的。该系统包括空间数据库和属性数据库两部分。空间数据库包括全国1:250 000地图数据和全国范围720个气象站点位置数据。属性数据包括2001、2002年在全国1 300个县约1 000种有害生物调查数据,194个气象站点从1950年到2001年的气象数据。利用地理信息系统软件平台MapInfo及其开发语言MapBasic开发了菜单、对话框等用户界面,可简单方便地完成查询有害生物信息,绘制有害生物发生范围专题图、插值图、每日温度、月均温、害虫年发生世代数估计及有害生物可能分布范围的估计等操作。The geographic information system (GIS) of crop pest distribution in China was developed on the basis of the crop pest data collected in 2001 and 2002. The system includes a spatial database and an attribute database. The spatial database is composed of 1:250 000 map data of China and 720 weather stations located nationwide in China. The attribute database includes the pest data investigated, which contain about 1 000 crop pest species collected from about (1 300) counties in China in 2001 and 2002 and the weather data at 194 weather stations from 1950's to 2001. Using the GIS software of MapInfo and its programming language Map Basic, a user-friendly interface such as customized toolbars, menus and dialog boxes was developed. This system could be used to query the pest species information, create ranged thematic map of pest occurrence and grid surface thematic map of pest occurrence, calculate daily temperature and monthly average temperature, estimate the generation number that a pest might complete during one year and the likelihood of insect distribution region, etc.
