The results showed that there was a good static fractal relationship between them, and the resulted fractal dimension was an efficient description of the accumulation of aboveground biomass in each organ. The dynamic fractal relationship showed that during the whole growing season, the increase of aboveground biomass had a self-similarity, being a fractal growth process, and the pattern of its increase was the fractal dimension D.
