Abstract: Since Levins(1969)proposed the term of Metapopulation,in sense of multiple,separate,local population linked by some level of genetic interchange,or a population of populations,it has become very popular in contemporary population biology.But in 1979,J.White also used the word“ metapopulation”for the sum of various component parts,with reference to morphological construction of a modular organism,And this usage of White's Metapopulation has been accepted and applied by some plant demographers,So that,there are two different intensions of the term“Metapopulation”,which cause confusions in population biology.This paper discussed and analyzed these intensions and discriminations, and suggested that the term of Levins can be used forever;the definition of white's can also be used,but the word“Metapopulationl”,he used must be given up,and it would be better to use“Metameric population”instead of it.According to the comprehension of the two terms,we can easily distinguish them.

Key words: fire behavior, flame length, residence time, moisture content, load, fuel bed depth.
