Ordination of plant communities at Nazlochai Basin in West Azarbaijan rangelands of Iran
One of the problems associated with community structure is how the spatial pattern of organisms in the community relates to the interaction of organism with the environment.Ordination is the technique of arranging unites (for example,forest stands) in a uni‐or multidimensional order in such a manner that the position of each unit along the axis or axes conveys the maximum information about its composition or relationship with the other units.Ordination is based on the assumption that community composition varies gradually over a continuum of environmental conditions.For this reason community can not be classified in discrete units ; rather the form a continuum changing in composition and structure over environmental gradients ( temperature, elevation, soil, and so on) (Grieg‐Smith, 1983 and Dyksterhuis, 1985).
