Abstract: Anew method measuring similarity among community food webs is developed based on adjacency matrices of community food webs. The similarity coefficient S = a/(a+b+c) is obtained by comparing two adjacency matrices, where a,b and c represent respectively the match numbers in 2?2 frequency table.
