  With the establishment of global biological monitor network and development
of remote sensing technology, data won't be a limitation, but the variance
brought by spatial heterogeneous and fractal will influence correlation
coefficient significantly with the enlarged sample scale. Those impede us to
find more intrinsic principle in ecology. Ecology is based on experiment, and
the experiment methods won't change with spatial. In that condition, if we
construct a system to evaluate the experimental difference, that may benefit
the study in spatial ecology. In that condition, we give a synthesis discussion
from the concept of data, experiment to analysis methods,and revise as well as
develop correlation and regression method to make it suit the demand of spatial
analysis. An experimental correlation system is established in this report.
