摘要
在研究可视化与空间数据挖掘关系的基础上,探讨了可视化在时空数据挖掘过程中的应用。利用可视化表现形式使历年来测量到的玉米产量数据和精准施肥数据充分地结合在一起,同时使人们更加直观、清晰地比较和分析玉米产量和精准施肥二者之间的关系。系统地分析精准施肥对玉米产量的影响,展现了多年来精准施肥的成果,作到修正现有的精准施肥策略、指导来年的精准施肥策略,从而使得玉米增产并且更加精准地预测玉米产量。
Based on the relationships between visualization and spatio-temporal data mining,the applic, ation of visualization in the spatio-temporal data mining proc.ess was discussed. The visualized expression of maize yieht data mid precision fertilization data enable people to directly and clearly compare and analyze their relationships. The effects of precision fertilization on maize yield were analyzed, the achievements of years of precision fertilization were presented,the present precision fertilization strategies were revised to guide the fertilization of next year,so as to im- prove the maize yieht and precisely predict the maize production.
