基于ArcGIS Engine的水稻生产潜力预测系统的设计与实现

Design and Realization of Rice Productivity Potential Forecast System Based on ArcGIS Engine

针对以往作物模型都是基于单点进行研究而导致空间外推不理想、尺度上升困难等问题,根据水稻生产潜力模型和栅格计算的特点,将模型与地理信息系统集成,综合利用空间数据和属性数据,在Visual Studio.NET 2005开发环境中嵌入ArcGIS Engine组件.利用COM技术,遵照软件系统设计思想,设计并实现了水稻生产潜力动态预测系统.该系统使模型参数得到系统化处理,模型计算更加高效,分析更加精确,能较好地实现水稻生产潜力动态预测功能,同时对农业资源管理也具有非常重要的作用.

Previous research on rice productivity potential models,based on a single point in space and then extrapolated,is not ideal and is difficult to scale up.This study designed a rice productivity potential forecast system,which makes comprehensive use of spatial data and attribute data by integrating the model with geographic information systems according to the characteristics of rice productivity potential model and raster computing function.Following the idea of the software engineering and using COM technology,ArcGIS Engine components were embedded in Visual Studio.NET 2005 development environment.This system can achieve the goals of more systematic model parameters,more efficient calculation and more accurate analysis.This system can be used to predict potential and dynamic rice production.It is also important for the management of agricultural resources.
