外文摘要：The debate on which exponent was correct, -3/2 or 4/3, was still a puzzled question in population selfthinning. To unify these two exponents, a new model linking population spatial distribution and the individual growth was provided here. Based on the fact that space was occupied by individuals, we found that the basic structure of even-aged and monospecific plant population was an equilateral hexagon, which was constituted of seven individuals. Furthermore, the individual volume, described with integration method, was proved to be proportional to power of length. In the fractal geometry opinion, the dimension of the section was fractal and varied between 1 and 2. So the exponent of self-thinning power law was a real number between -1 and -3/2. We concluded that -4/3 power law was not universal in self-thinning process, but a transient value in the range of-1 and -3/2.
