【Abstract】 The mathematical law of random aggregation and the physical mechanim of spatial extension of systems of towns were presented with fractal theory,and evidence was given by providing the calculated results which were based on measuring the distribution of towns in China.This discovery would contribute to the theory and application research of urban science.更多还原
