Form of Good Models

Growing Stock Illustration

Abstract

To ward off defined algebraic expression I illustrated growing stock with three figures o􀁖o. 0 was to exist, 􀀽 was to turn to something, and 0 was mortal. A growing stock was illustrated with a crown and a growing stem. Growing stems were illustrated with individual stands and a fully stocked stand. Extinguished stems and the upper limit of stand volume could be observed in the space of the illustration. And a yield table was illustrated with main crop and some growing stock. The illustration was a clear sketch with many temporary factors around the subject, growing stock. Therefore it was easy to show increase instead of decrease. The result said that the form of increasing figures was valuable and good as a growing stock model. And the acute decrease risk which followed a defined expression was shown, and it might not be said that the illustration with many temporary factors was proper to be sensible of the risk or to ward off it.
