| AbstractAs an important component of modern agriculture,urban agriculture is a kind of agriculture which distributes in the city and its surrounding areas and usually relies on and gives services to them. It is a necessary requirement that applying computer technology and network technology to urban agriculture. Accordding to the current developing requirements of Beijing urban agriculture,the key construction region of Beijing suburb should realize agriculture information, enhance the publicity and play a good demonstration role. This paper used information method to propagandize the construction achievements of the corridor on the Beijing-Chengde Road(in Beijing). Then it designed and implemented Beijing-Chengde Road Urban agriculture information system based on J2EE, ArcIMS and spatial database technology, which formed a information technology product to help, enrich and convenient people. The main contents of this paper inculde following five aspects:(1) The status and trends of the Beijing Municipal Urban Agriculture; (2) researching on related technologies and building methods of WebGIS; (3) researched on some key technologies of system building, such as spatial databases, Ajax, MVC structural model,etc. (4) the design of Beijing-Chengde Road Urban agriculture information system, including system design and functional design; (5) Using the agro-ecological mathematical model to compute and evaluate the land use before and after constuction of Beijing-Chengde Road's urban agriculture and the value changes of eco-system services in the corridor. This subject completed the research and design of Beijing-Chengde Road Urban agriculture information system, with some degree of innovation,which provided a good scientific and technological support for the construction of Beijing urban agriculture. |
