With the rapid development of Internet and geographic information technologies, people's demands to geographic information systems (GIS) become increasingly.Network Geographic Information System (WebGIS) as the a combination of points of network technology and GIS technology, since its inception, its development with the progress of computer technology are closely related.Alien species invasion has become one of the world's top four for today's environmental problems.Our country is one of the countries which is suffering the worst invasive alien species.As China is increasingly becoming a large trading nation,our country suffer the risk of invasive alien species will continue to grow, our country be on guard the invasion of alien species will be a long-term and arduous task.Established a database of invasive alien species, can provide basic information for scientific research and can Provide a scientific basis for the legislative for alien invasive species.Helps to strengthen international exchanges and cooperation in security certification and important security data sharing with the isolated information case.And helps to strengthen exchange information with the global invasive species database.Therefore, by using modern information technology, the development of high degree sharing information network of invasive alien species database system is the important urgent need to resolve issues.In this study, Chinese Academy of Agricultural Sciences of alien invasive survey information for the base data, collecting all relevant maps, property information, to form the basis of spatial database;full investigation and practical needs, alien invasive species database, security requirements, combined with issues related to research and development based on the alien invasive species database system, basically meet the needs of agricultural science and technology workers or experts, government policy makers need to guide production practices, to prevent invasive alien species cause more damage on our economy and a series of production safety issue. Firstly, the study background and significance were discussed and Combination with the current mainstream technology, as well as specific needs analysis,targeted research projects put forward the purpose and contentSecondly, Key technology in system develop process has been carried out a summary.It introduces the concept and main characteristic of WebGIS technology and Web Services idea.The spatil database engine(ArcSDE) technology is also present briefly.Thirdly, according to the requirement analyst,it carries out the overall design of this system,expounds the design thought and technology route, and also describes in detail the research method,design principle, exploitation environment,function structure and database design.Then the main function and implement method of the five modules are set forth detailly.At last,after, summarizing the main characteristic of the system,the key technology, innovation idea and shortage of this system are brought forward,and the application foreground is prospected.
