摘要
介绍了基于ArcGIS Engine开发区域性粮食生产安全预警系统的结构和功能,提出了粮食生产安全预警采用的模型,并以东北三省为例,采用粮食生产安全预警系统进行了粮食生产安全的分析和评价研究。结果表明,基于ArcGIS Engine的区域性粮食生产安全预警系统,能够实现区域粮食生产的有效监测,达到粮食生产安全预警的目的,对保证区域粮食生产安全具有一定的实际意义。
The structure and function of the early warning system for regional grain production safety on the basis of ArcGIS Engine are described in this paper, and a model for grain production safety pre - warning is proposed. With Northeast China as an example, the authors carried out an analysis and appraisal of grain production safety based on the system. The result shows that the regional early warning system for grain production safety on the basis of GIS can realize the effective monitoring of regional grain - production and achieve the aim of pre - warning of grain production safety. Hence it has certain theoretical value and practical meaning in guaranteeing the regional grain production safety.
