Study On Eco-island Decision-assistant System For Chongming Based On Model Base

With the rapid development in information technology, the informatization of Eco-system has been carried out and is becoming an effective way of management of ecology, which adopt certain technological means to achieve automatic gathering, the dynamic analysis and the monitor, the coupling simulation and the predict of each kind of ecology essential factor of the Eco-system that then may achieve the surveillance, the analysis and the auxiliary decision-making of the ecosystem management.This paper using the technology database, SDSS and Internet, arranging the result of the current reseach of Eco-Island for Chongming,creating database for basement information of Chongming ecology,has achieved the mining,sharing,management and visualization of essential elements of information of Chongming. This paper which contacted the developmental pattern of society with process of Eco-system, integrated the modelbase which has the function of imitation, evaluating and decision,has achieved the management of major issue of ecology and environment of Eco-Island for Chongming and made strategic decisions to Eco-Island for Chongming by the means of informationizition, intelligentizition and visualization. SDSS is gradually becoming a important method of research of Eco-system.Firstly, this paper designed the system based on the theory of software engineering, including the function framework, UI, infrastructure of system and design of model base. This paper designed the function framework and system module based on requirements analysis. Then this paper designed the model base according the requirements of decision and fixed the Three tier architecture as the structure of the system.Secondly, this paper built and implemented a unique model base according the ecological ragime of Chongming. Model base is the key component of DSS. In the domain of ecology, models has become the most important method to describe ecological problems, and ecologists have built many classic model system. However, these model systems may not be suitable with the ecological condition of Chongming.Finally, The paper made a study on the implement of the key technology of the system, including the implement of decision process, client and system architecture, and provided a lot of code snippet. On the base of the implement,the paper took the water model as example to introduce the application of the system.
