摘    要: 引入知识模型概念,通过光、温、水、土、施肥、灌溉、社会等因子的逐步衰减,建立作物生产潜力估算的知识模型。将知识模型与数据库有机结合,以Mapinfo5.5为系统开发平台,利用MapBasic和VB程序设计语言,建立基于知识模型的作物生产潜力分析系统,实现作物生产潜力评价的计算机辅助决策。以江苏省作物生产系统为案例,应用本系统对江苏地区作物生产潜力区域优势进行实例评价,并与实际单产相比较,进行单产潜力、潜力系数和总产潜力的对比分析,确定作物生产地域优势。

关 键 词:知识模型  GIS  作物  生产潜力  评价

Abstract:The concept of knowledge model was introduced, and the knowledge model of crop potential productivity estimation has been set up by the factor attenuation of solar radiation, temperature, water, soil, fertilization, irrigation and the social factor. Based on the support of MapInfo 5.5 systemic development platform and knowledge model, with MapInfo development language including MapBasic and VB6.0, an analysis system on crop potential productivity was developed by integrating the knowledge engineering and database. The computer aid decision of crop potential productivity has been realized. An application example in Jiangsu province was provided, by comparing to the practical yield per unit area, the potential yield per unit area, potential coefficiency, potential productivity were analysized qualitatively, the regional superiority of crop production was decided.
Keywords:Knowledge model  GIS  Crop  Potential productivity  Evaluation
