Pattern diagram
basic content
Firstly, the concrete image is transformed into a graphic image, and then the graphic images are compared to find out the relationship between the structures of the real objects represented by the graphic images. Finally, the researcher produced a result in his mind that the representations of anatomical structure formation in different periods were compared with each other and expressed by language symbols and charts. For example, the ovary structure and fruit structure of various plants are similar. After comparing the results of tracing and dissecting the flowers of various plants, the researchers retained the similarities and removed the differences, and the obtained fruit map of ovary development lost the characteristics representing specific plants and became a structural model map of ovary development fruit with universal characteristics.
A graph that represents geographical things and principles with block diagrams, arrows, lines and words is called a pattern diagram. Pattern diagram can make some concepts and principles more concise and clear. How to read it? It is necessary not only to find out what problems the pattern diagram explains in the relevant knowledge points, but also to transfer knowledge on this basis and lead to other knowledge.
For example, if the map of the circulation bureau in the middle and low latitudes of the northern hemisphere in the ocean current model map is simplified to the following figure, we can investigate the knowledge of atmospheric circulation, water cycle, crustal material cycle, cyclone or anticyclone, biological cycle and so on.
