what is the meaning of mantel test results to compare 2 matrices ??
Matrix 1: Data Distance Matrix
Matrix 2: Data Distance Matrix
Matrices are 355 x 355
Observed Z = 3894672599.85108
Correlation = 0.31206
t = 17.81190
Left-tailed p = 1.00000
Right-tailed p = 0.00000
Two-tailed p = 0.00000
Permutation Results (999 permutations)
# of Permutations < Observed = 999
# of Permutations > Observed = 0
# of Permutations = Observed = 1
Left-tailed p = 1.00000
Right-tailed p = 0.00100

The Mantel test measures the correlation between two distance matrices. The null hypothesis of the test is that the distances in one matrix are not linearly correlated with the distances in the other. If you don't know what a test does, you should learn about it, in particular about when it is valid and when it is not. In this case, it is important that the distances in the two matrices are computed using variables that are independent between the two matrices.
Ok, but How can i know the best matrix according to Mantel test ??
what is this values referred to ??
This is where you need to do your homework. Try to understand the question that you're asked, whether the Mantel test is the appropriate answer and if so why.

Why do you want to do a test, if you don't know what you are testing???
Is this for homework?
yes , it is homework :)
