Cotton Potential Productivity Evaluation System Based on Abstract: 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. |
