The study is made of the spatial structure of the systems of cities and towns in Central Plains,mainly including North Henan,China,using the theory of multifractals.By means of the box counting method and μ-weight formulae,we calculate the values of the Lipschitz-Hlder exponent α(q),the fractal dimension of the support of singularities f(α),the sequence of mass exponent τ(q),and the dimensions of fractal measures D q of the urban systems in the studied area.The resultant values show that there is a scaling...
