基于知识模型和GIS的棉花生产潜力评价系统

Cotton Potential Productivity Evaluation System Based on Knowledge Model and GIS

引入知识模型概念,建立以棉花生产潜力知识模型为特征的知识系统,将知识工程和数据库有机结合,以 Mapinfo 5.5 为系统开发平台,利用 MapBasic和 Visual Basic程序设计语言,建立基于知识模型的棉花生产潜力评价系统,实现棉花生产潜力评价的计算机辅助决策。应用本系统对江苏地区棉花生产潜力进行实例评价,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,确定棉花生产地域优势。

The concept of knowledge model was introduced, and cotton potential productivity knowledge model has been set up. Based on the support of MapInfo 5.5 systemic development platform and knowledge model, with MapInfo development language including MapBasic and Visual Basic 6.0, an evaluation system of cotton potential productivity was developed by integrating the knowledge engineering and database. The computer aid decision(CAD) of cotton 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, potential coefficiency, potential productivity were analsized qualitatively, the regional development advantage of cotton production was certificated.
