【Abstract】 This article discusses the main structure of the information service system for agricultural ecological environment,which is based on WebGIS,the main design points of this system,and the functions of this system.It also makes an analysis of the key technology applied in it.With the agricultural ecological environment as the core,this system applies database technology,combines the geographic information system and applies the model to realize the edition,inquiry,statistics and the spatial analysis of graphical information. In this way,this system can provide practical information service for the government decision-making sections and realize the ADM(Aid in Decision Making) policies for regional development and environmental protection based on the WebGIS technology.All these lead to the realization of the integrated platform of collecting, transmitting,managing,analyzing,and decision-making of the resources environmental information.更多还原
