| 摘 要： | 光谱曲线的差异是由多种因素所致的,不同地物光谱反射曲线是地物对电磁波反射或发射差异的集中体现。由此可根据不同地物对入射电磁波反射形成的不同光谱曲线来区分不同的地物类型。据此,我们将地物光谱的时空特性变化作为研究的重点,运用地学图谱理论,结合超图时空概念模型,对地学现象时空特征及其规律的概念性表达,并使用面向对象技术结合影响烟草长势的时空因子,构建了一个实用的时空推理模型,并应用于烟草的长势监测。

| Abstract: | The spectrum curves of different objects are the centralized embodiment of the objects reflecting to electromagnetic wave. The difference of spectrum curves are caused by many factors, we can differentiate the different object types according to the different spectrum curves. It is obvious that the spectrum reflects not only the status of the objects, but also the environment surrounding them. According to this, we took the changes of spatial and temporal features as the foci of our study, and made the best use of geographic Tupu theory which primarily expresses the spatio-temporal features of geographical phenomena, and of the conceptual expression to the rules in combination with the hyper-graph spatio-temporal conceptual model, as well as used the object-oriented technology to combine several factors affecting the growth of tobacco, constructed a model which satisfied the practical application requirement, and finally had the model used in monitoring the growth of the tobacco. Through practice, the model proved to be feasible in theoretical aspect and actual use. |
