摘要: Summary. Detailed studies of ecological distribution and habitat specificity require objective, quantitative data which are rarely available in the reference system customarily used for designating relations. A scheme description was developed tested a variety situations Africa North America based on selection set measurable features or dimensions, each graduated qualitative evaluation. A procedure recording measurements field is described. Examples presented showing how may be applied erecting vegetation formulae various degrees refinement, making semi-pictorial diagrams, analyzing subtle differences by different species populations.
