Test them for what? If you can formulate your hypotheses more clearly, you might try the model matrix approach outlined in
Legendre, P. and M.-J. Fortin. 1989. Spatial pattern and ecological analysis. Vegetatio, 80: 107-138. and subsequent references. But there might be better ways, depending on what you are trying to achieve.
