基于改进原型法的太湖流域区域环境信息系统的进化式开发——以无锡市为例

Development of Environment GIS in Taihu Catchment Based on Improved Prototyping: Taking Wuxi as Example

针对传统应用型地理信息系统开发方式的缺点,结合了结构化生命周期法的有效管理模式和原型法快速开发的优点,提出了一种基于改进原型法的进化式开发方法,并在位于太湖流域的无锡市进行了开发实践.

Because of the shortcomings of traditional methods of developing GIS, the author brought forward an evolving method: the improved prototyping to develop GIS that included the efficient management of structure based life cycle method and the fast development of prototyping. In the development, the risk evaluation is imported to control the prototype evolving times and each time of evolving would include all steps of structure based life cycle method. At last, we have used this method to develop the environment GIS of Wuxi, located in Taihu Lake catchment. After getting the primary requirements of users, we started to design the first prototype. Then interacting with the users, the evolving of prototype would be controlled by risk evaluation. After 3 times, we got the final product. Groping for the efficient way to develop EGIS would urge the environment management into a new information era.
