摘要
基于农地适宜性评价的一般流程,设计和实现了一个农地适宜性评价空间决策支持系统。探讨了其组成结构及各部分具体内容,并综合运用Geodatabase数据模型、ArcObjects组件技术、ADO接口技术等开发和实现了该系统。系统应用于封丘县农地适宜性评价,实践结果表明,系统能有效的管理空间与属性数据,并且起到了辅助决策的作用,还具有较好的通用性、可移植性和可扩充性。
A spatial support system on farmland suitability evaluation was designed and implemented based on the commonly procedure of farmland suitability evaluation in the paper. The components and their content of the system were discussed,and techniques such as Geodatabase model, ArcObjects components, and ADO interface were used to realize the system. The application in farmland suitability evaluation in Fengqiu county indicated that the system can manage spatial and characteristic data efficiently, and fulfill decision support correctly. Besides, the currency, transplantability and extensibility of the system was mentioned.
