Based on sufficient system requirement analysis,this paper identified three-layer distributed architecture which based on B/S mode,Dreamweaver8.0used as development platform, HTML, CSS, JavaScript were adoptedas development languages, database management function of Microsoft Excel as well asIE browser ActiveX controls were used to complete development and implementation ofthe system. The main results showed as follows:1. Database of diseases and insect pests of common garden plants of Hebei provincehave been arranged, which included62plants species,83diseases information,129insect pests information,84diseases picture and152pictures of insect pests.2.
